The entire taillight unit can be removed by removing the black plastic headed nuts that hold the unit in place. Use a 6 point socket to prevent rounding the plastic nut off. If the nut does not come off easily, spray under it with a good penetrant like Kano "Kroil," let it soak for a while, then try… again. The bulb sockets come out by pressing the lock tab and turning the socket counterclockwise about 1/8 turn and pulling them gently out. (MORE)
First and fore most try your local dealership/manufacturer's parts department or repair department.. If you don't have any luck there try a local car stereo/alarm shops.Believe it or not that is where I found my wiring diagram for my 1959 cadillac.(Example: personally owned shops will probably be m…ore curtious and friendly, but you can also try Best Buy installation shop/ Circuit City/Ultimate Electronics,. . . . . . .get the picture????. Hopefully this will help you it did me.. Sept. 2007 I went to my local library (Gwinnett County, GA) and user their online subscription to the Chilton data base. It cost me $0.15 to copy the page. The brake lights on my van were not working. The third light worked fine. If the van lights were off and the brake pedal pressed, the dim (marker filament) would turn on. If the lights were on and the brake pedal pressed, the dim (marker filament) would turn off.. This problem was caused by a faulty ground connection (black wire) at both brake light bulb sockets. The fix was simple and only requires a little electrical tape. I simply removed the wire retainer clip from each brake light socket. Then I pulled on the black wire. It pulled out about 1/8 inch and stopped. That fixed the problem. Do not replace the wire retainer as it will push the ground wire back into the socket breaking the ground connection. Use electrical tape to insure that the wires are held in place in the socket. Both brake lights were fixed in this way. (MORE)
What does it mean when you put your foot on the brake the brake pedal pulsates and the steering wheel shakes?
This is the first sign that the brakes are going, they may need to be replaced, but they may be able to just turn the rotors and you can still get alot of good use out of them
you need to have your brake rotors turned or even replaced, this is a 200.00 fix or so
Answer . \nBrakes are a very important, so proceed with great care. There is too much to list here, I would recommend buying a Chiltons or Haynes manual for reference. These can be purchased at most parts stores for less than $20.00 new, or for even less on Ebay. I also advise to ask around, one …of your friends, relatives, or co-workers may have some working knowledge, but I'd still get a manual. (MORE)
What would cause the wheel cylinders not to move when brakes are applied in bleeding the brakes on a 1980 chevy van; and when bleeding the pedal does not go to the floor?
Answer . \nWithout seeing it, I would say that the wheel cylinders may have rust/corrision in them preventing them from moving in their bores.That would explain why the pedal does not go to the floor when trying to bleed them.. Answer . \nCrack the bleeders open and see of fluid comes out eit…her one. IF it does, replace the wheel cylinders. IF not, there may be a restriction further up the line, collapsed brake hoses, master cylinder or a (proportioning?) valve problem. (MORE)
Why would the rear brakes of a 1996 Chevy Corsica engage very hard with the slightest touch of the brake pedal?
Answer . The rear brakes are called a dual servo brake system... it uses one shoe to activate the other in a braking situation. When the rear brakes are over adjusted the slightest touch of the brake pedal will cause them to engage. what is actually happening is your rear brakes are engaging …before the fronts even get close. You need to either back off the adjusters yourself if you know how or take it to a garage and have them back them off. (MORE)
1994 Chevy astro allwheel drive van and the brake pedal occassionally locks and you have no brakes but can pump 3 or 4 times to get brakes back sometimes humming associated with brakes coming back?
Answer . If you're saying that the brakes lock with the brake pedal UP, it's an ABS problem and it will probably be very expensive. You could check the wheel speed sensors and hope that's the problem. Otherwise, you'll need to have the code read and unfortunately you can't yet buy an ABS code re…ader.\n. \nOn the other hand, if the brake pedal is going to the floor, check for fluid or an internal master cylinder leak (MORE)
A Chevy van may be hard to start because the engine may bemalfunctioning. Bring your Chevy to an auto body shop and get atune up performed.
ABS (anti-blocking system) starts... to avoid locking brakes.. Answer . It may also be a warped rotor and brake pads worn out, depending on what you mean by hard braking.
Usually when a brake pedal feels more stiff than usual, there is avacuum leak. The brake lines probably should be bled.
Why would a 1995 Ford Explorer XLT have a hard shift and steering wheel and brake pedal vibration at the same time?
With your foot on the brake, put the transmission in drive, then reverse, drive, then reverse. If you hear a clunking noise, think about replacing the U-joint in the drive shaft with a heavy duty unit from NAPA auto parts. Get one that has a grease fitting so you can service it.

Whats wrong when your brake pedal goes all the way to the floor and its real hard to stop in a 1990 Chevy caprice classic?
LOW BRAKE FLUID!!! (very dangerous!). Fill reservoir, bleed the brakes, fill again to the correct level.. After a few times braking, check fluid level.. if fluid is lost, check brakes for leaks and have it fixed asap!!
Most likely the vacuum has been disconnected from the power booster. ie. a line is off (engine should run rough) or the plastic check valve is defective. You should hear a sucking sound from the hose connecting manifold vacuum to the brake booster. repair the leak and you should be OK. Its always po…ssible the booster has failed. that is uncommon but expensive. Good luck (MORE)
Hardness in the brake pedal can because by low brake fluid. Air inthe brake lines can also cause the pedal to push hard.
Sometimes a piece of carbon will get caught in the EGR Valve. If is is hard starting, idles rough, and the brakes are hard, check the EGR Valve, it probably has a piece of carbon stuck, keeping it open.
What is the problem when you can not steer nor brake the car 96 GMC safari its very hard t o steer the steering wheel and hard to brake its very hard when pressing the brake pedal?
There is a vacuum attachment on the power brake booster. If there is a vacuum leak this part could be causing the brakes to be hard, or this part could be the vacuum leak. The steering could also be vacuum assisted occurring from the same source. Are there any other symptoms (i.e. vent/floor/defrost… not blowing air or changing properly)? (MORE)
I have a chev g1500 2000. Does anyone no how to ajust the rear brakes?
Remove the serpentine belt by going clockwise with a 3/8 breaker bar on the belt tentioner UNDER the truck (I had to use my 1/2" breaker bar with a 3/8" adapter). Have someone remove the belt off the alternator as you remove tension under the truck (jack the truck up just a bit to fit) there is a sq…uare 3/8" for a socket ratchet to fit into on the tentioner underneath. Then remove the 2 - 13mm bolts on the alternator on top of the truck (under the hood). They are long bolts and rather tight, I loosened them with a breaker bar and then air ratcheted them out the rest of the way. Even with my cheap $20 air ratchet and $40 compressor, it does the job because there is not much room in there. Now pry the alternator loose with a BIG screwdriver, side by side until it's flopping around a bit. Then remove the 1/2" nut off the alternator wire and remove the wire. Now the fun part, getting it out of the engine compartment. It comes out BACK first, take the bolt to the wire out first and the entire black rear towards you (barely enough room). The pulley will be facing towards the engine and wiggle back and forth until it slides out. Good luck on the arm cuts! I didn't put my new one back in yet but I am sure it will be fun. Tom. (MORE)
The most common is that you either have a vacumm leak or the brake power booster is failing internally. The way to check is:. Run the truck and check for hissing noises under the dash (brake pedal area) and under the hood. If no leaks are heard then shut it off & don't touch the brake pedal. Beside… the master cylinder there is a fat rubber hose going to the big round thing the master bolts to (power booster). The hose goes to a one way valve in the booster. With the vehicle off you should pull the valve out of the booster. It should be hard to pull out but it will come out with a hissing noise as the vacumm in the booster escapes. If it doesn't hiss then you may have a vacumm supply problem, check valve problem or the booster itself is leaking and the booster can't work without vacumm. With the hose disconnected start the truck & put your thumb over the end of the hose & see if there is vacumm coming from the engine to the booster. If no vacumm present loof for a supply issue. If it does hiss when you pull the valve then you need to undo the 2 bolts holding the master to the booster & pull it away from the booster CAREFULLY as not to damage the lines. Look at the rear seal of the master where it bolts to the booster to see if it's wet. If it's wet the brake fluid is leaking into the booster and has damaged the rubber inside. If no leaks are found it's also possible that the booster has failed due to age. At that point you will need to replace the booster and/or master. (MORE)
Im not 100 percent shore but I belvie the ecm is located directly beneath the fuse box under the hood of the vehicle. It seems to be completely enclosed. I also read somewhere that they are not interchangable. please double check this.
Where is the left rear brake and turn signal relay located on a 2010 Chevy express van. V-6
there are three things that make a vehicle run: spark.gas and air. Without one of the three, the vehicle will not run. A simple test is spay starting fluid straight into the carborator or throttle body. If the engine tries to start, then it is a fuel problem. the second test is to take the spark plu…g wire and hold it next to a grounded surface. if you see a spark while the engine is starting, then the spark is okay. The last thing to consider is if the timing is off (MORE)

"Brake Fade". If you hold your foot on the pedal for a long time, the brake pads and rotors will heat up to the point where they cannot dissipate any more heat energy.

Why would a 2002 Chevy Express brake lights work when the headlights are off but when you the headlights are turned on the brake lights are on and go off when you press the pedal?
i found it to be the tail light harnesses go bad . a common problem with them because the bulb sockets short out.
you might want to check to see if the recall was preformed on it the was a problem with no power assist if it has not been down it will be free
Verify that the vacuum source for the brake booster is working. Might need a new booster.
The cause of hard brake pedal is malfunctioning brake booster. Check the hose from the intake manifold going to the brake booster for cracks or leakage, replace if necessary. Check the one way valve located in the middle of that hose, make sure the valve opens when you put pressure on one port.. If …all those mentioned are ok, the booster itself needs to be replaced....

Sounds like the power brake booster is bad, that is what the master cylinder is bolted too. There is a rubber hose that has a plastic valve in it were it snaps into the booster, Pull that rubber hose out of the booster and off of the engine, Now the end that you took off the engine. You should be ab…le to suck through the line, but not be able to blow through it. If you can then replace the valve, It is a one way valve. If that is all right then hook hose back up to the engine and start engine, You should hear a major vacuum leak at the valve end, put you finger over the valve and it should stop making noise and engine should smooth out. If it don't the rubber hose must be leaking or the tube on the engine were the hose hooks to is stoped up. (MORE)
Most likely you do not have anti-lock brakes in your vehicle. Other possible answer is that your anti-lock brakes are malfunctioning. If you have anti-lock brakes you should see a mechanic as soon as possible.
Probably warped brake rotors. They can be removed and resurfaced or replaced with new ones.
Why won't our 05 Chevy Express van start after we changed the fuel pump when it will run on starter fluid?
make sure you prime the new pump with fuel so it is not dry, pour or squirt fuel into pump. From original poster:. We took the van to a mechanic. He tested both the old and the new fuel pump. They both worked. We checked all of the fuses and relays and they were all good. So he changed out the fus…e/relay panel under the hood of the van and then it worked. The van has been running fine ever since. (MORE)

Why does the brake light come on when you touch the pedal and go out when you release the pedal on a 1990 jaguar XJ6 The brake pedal is hard it has brakes but you have to press the pedal down hard?
if the brake pedal is hard you might first want to check if the mineral oil is full, get the castrol mineral oil for jaguars with the attached pump. Make sure the oil level is green with a black dot, if is clear with a black dot then the container is empty and it needs oil.,, Good luck bud..!!
The Astro Van power steering and brakes work off the same pupm. Check the pump for fluid. If it's full and the brakes and steering still hard you must replace the pump
What is the problem when you can not steer nor brake the car 97 GMC astro its very hard t o steer the steering wheel and hard to brake its very hard when pressing the brake pedal?
For several years of the Chevy astro van had a power brake and power steering system that was linked together. Instead of a brake booster, the power steering pump provides power to the power brake system. Often, if the brake pedal would become hard to push, it is a power steering pump problem. Chang…e the power steering pump and the power steering fluid and your problem may disappear. (MORE)
first remove the tire and then you can remove the two larger bolts on the bracket that holds the cylinder and brake pads. The bolt size is either a 13/16 or 3/4 inch. Tap the rotor with a rubber mallet or hammer, if their are clips on the studs you need to remove them first and the rotor should come… off and then slide the new one on over the studs and replace the clips if possible but not necessary. Next put the caliper back on and then replace the two larger bolts. You may have to open caliper cylinder by prying a flat head screw driver in between the pads and rotor then remove two smaller bolts which are 7/16 to 5/8 inch take out pads and replace with the new ones and shims if possible . make sure all bolts are tight as possible when putting back together also do not touch the rotors or brakes with dirty hands or gloves don't allow grease to get on these parts where the pads touch the rotors. will cause noise latter on.

On modern vehicles the brake system is enhanced by a vacuum operated "booster". This makes the brake pedal softer and more responsive. When the engine is turned off the engine no longer produces vacuum to supply the booster so the pedal gets hard.
2001 Chevy Silverado 2500HD and the power steering pump is vibrating really bad when you press the brake pedal and when you turn the steering wheel what could cause this?
The front brake rotors are warped. It's not the power steering pump if it only happens when braking. One or both of the rotors need to be replaced. Overheating causes this, especially if the rotors are old or have been turned as part of a previous brake job on the truck.
The first thing to fail in the steering system are the idler arms - they do not have lube fittings from the factory. Change these and the steering will feel like new.
Low fluid or something is wrong with your power assist (booster). Having it vacum tested could be a good idea. The Booster only works when the engine is running and a few seconds up to half a minute after it has been turned off.
I get about 12 MPG towing a boat - I get about 16.5 MPG on highway - fully loaded down (6 people, luggage etc.). I have a 5.7 Litre, 2000 Chev Express.
When the car is off the brake pedal is hard to push but with the car on the pedal goes to the floor?
sounds like you have a leak in your Brake Boost Controler, you should also check to see if there is any leaks in the vacuum lines that connect the engine to the brake booster.
2005 town and county van brakes dont work when you push down on the pedal I have to use both feet very hard All I did was change the spark plugs?
Check to make sure the vacuum line is hooked up between the intakemanifold and the brake booster.
Your power brake booster may be defective. You may have a vacuum leak or the booster itself could need replacing.
Because it has a hydraulic booster that supplies both systems and something is wrong with it.
A hard brake pedal can be caused by several different factors. It can be as simple as the brake pedal getting caught on something to the power brake booster being bad. You could also have a brake pad or shoe that is sticking, causing the brake fluid to boil. When brake fluid boils, it expands and ca…n cause the hard brake pedal that you feel. A brake pedal that is hard to press can also be caused by a build-up of water in the brake line. The water in the brake line lowers the boiling point of the brake fluid. A hard brake pedal can also be the result of a restriction in the brake line, such as a bent brake line or foreign material in the brake fluid. The most common cause of a hard brake pedal is the sticking brake pad or shoe, causing the brake fluid to boil. Tracking down what is causing the hard brake pedal can be frustrating, to say the least. Take the vehicle for a drive and when you come back, feel your brake lines near the wheels. Caution: The line may be very hot! If one is extremely hot, you may have just found the culprit causing the hard brake pedal. (MORE)
