Question about 2003 Chevrolet Express

1 Answer

I purchased a 2004 chevy van yesterday, the brake light and ABS light both stay on. Not much brake pedal, goes almost to floor but seems to stop van good. Is it possible its just air in the syatem? If so how do you bleed an ABS system?

I have had the ABS light come on and stay on on a 2000 Suburban and a 2003 suburban. In both instances the brake system was fine. If you have not done so I would recommend you have the system checked for codes. If there are no error codes and the system is functioning properly the problem with the light staying on can be solved simply. Or at least I hope this solves your problem.

There is a small ground wire that is secured to the top rear of the engine block. It is on the passenger side of the engine. To find it remove the engine cover and reach back to locate the connection. Over time the ground connection gets compromised by dirt, grease, or corrosion. You need to unbolt this connection, clean the surfaces and re-install. On a friend's truck I just reached back and twisted the connection to seat it better and the lights have not come back on.

It sounds too simple but if it works it is much better that giving money to the dealer or a mech to solve the problem.

If you have brake fade that is if you hold the brake pedal down and it slowly goes down to the floor you probably need a master cylinder

2005 chevy duramax 4x4 brake pedal goes all the way to the floor, ABS light on


You need to add BRAKE fluid. After that, blead your brakes. You need to find out where the brake fluid went. If there are no leaks, you need to check the remaining life on all four brake sets. If you have no leaks, chances are pretty good that you need new brakes.

1999 corolla, brake pedal goes to the floor. how can we fix the brakes?


is the abs light on?the abs system only effects the pedal when you are stopping quickly to activate the system. you still have a hydrualic brake pressure problem. are the rear brakes shoes or pads? rear shoes out of adjustment can cause a low brake pedal.even though the master cylinder has been replaced doesn't mean you got a good part.if the part was a remanufactered part very likely it is bad. to determine if it is the master cylinder, plug off the lines from the side off the master cylinder and hit the brake pedal. if the pedal stays up look for a problem elsewhere in the system. if the pedal drops the the master cylinder is defective.

I have 2004 dodge diesel 2500 and when i turn my wheel left my abs light comes on and brake light comes on my brake pedal goes to the floor and i have no brakes and when i turn the wheel back the abs and...


Its the wheel speed sensor, or the wires are damaged. Turn the wheels to the left and then go look at the harness. is it streched out? (as in not enough slack) Is it touching or rubbing something. Has it come loose from its clips? Look at the face of the sensor. A few scratches are okay but, if it looks hammered, its probably damaged and should be replaced. If the hub bearing was bad enough to allow contact damage to the WSS you would have much bigger problems.

What causes the brake pedal to go almost to the floor and there seems to be no anti lock system


First test the master cylinder.with the engine off. Is the pedal firm. Is it holding pressure.If you say yes the master cyclinder is good. Now turn the vehicle on. does the pedal go to the floor.?.Now the ABS light doesnt have to be on to detect a problem ABS modules do fail. If it goes to the floor with the engine on and doesnt go to the floor with engine off. ABS motor module is no good. Why because the ABS motor pistons are not at it proper postion. Remember engine off we tested brakes without the ABS. Key on engine running we now test ABS. if it sink at this point the fix is a new abs module.Here the thing if you replace the module it will have to be flashed , the engine management will not communicate with it or recognize it

94 s10 chevy 2wd brake pedal fades to floor before stoping


Might check around the big black round muffin shaped chamber adjacent to the master cylinder for a loose vacuum hose or crack therin; the hissing sound seems likely to be the air rushing in as you loose the vacuum that supplies the power to assist your braking effort (power brakes)---as this goes, so goes your peddle until it reaches the actual piston pushing the brake fluid (which should be firm like with non-power brakes).
...maybe have an assistant push on the peddle while you listen with a piece of hose or a stethescope to find the leak (or I suppose the power unit diaphragm could be shot/leaking--hence replacement), but since you said after bumpy road etc, one could hope for a simple dislodged vacuum hose or fixable crack.

ABS and Brake light stay on plus pedal is soft after tight turn


sounds like you have low brake fluid pressure and the pressure sensor is turning on warning lights saying there is low pressure and also pedal going to floor indicate this, sounds like master brake cylinder is worn out/broke and needs replace ment
