I have a 1996 GMC Jimmy, and I believe I am having problems with the
brakes now. It seems that when I have to press them hard (to stop
suddenly) they grab, let-go, grab, let-go, and all while it is
grabbing the tires are screeching, but it's not stopping like it
should. It takes forever to stop when I NEED to stop. Please help!
ABS light doesn't come on and isn't on. The light turns on with the
rest of the "idiots lights" when I start the truck like normal.
During a hard stop the entire truck rocks while, and pulls to the
If you mean that you try to do a panic stop - stand right on the brake
pedal, and the truck exhibits this type of pulsed braking, then that's how
it should work. ABS does exactly that - it applies the brakes and releases
them based on it sensing the wheel locking up. As for the screeching -
please explain more. Is it little chirps? What is the air pressure in each
tire? What is the condition of the tires? Little chirps would be expected,
especially coming from the rear since the box of the truck is very light and
allows the rears to lock up very easily. If the tire pressure is incorrect
I would also expect some screeching, but not a lot - again, more like
chirps. Finally - if the tread is worn badly I would certainly expect
If the ABS light is not on that's a good thing. I'm guessing that you're
aware that when it comes on it is signifying a fault condition.
Your truck pulling to the right is an indication of uneven brake pressure at
one of the wheels. Either your left side is not actuating enough or your
right side is actuating too much. What is the condition of each rotor and
pad set? Are the rears properly adjusted? If you are getting any sort of
motion (what you refer to as rocking - please explain that better), then
you've got worn brake parts. Warped rotors, worn pads, out of round drums,
something of that sort. Sounds to me like you've got to start with the
basics and take a close look at the condition of those brakes.
