Question about 2002 GMC Sierra

2 Answers

I have a 2002 sierra gmc 4 x 4, when I come to a rolling stop the break peddle gets hard and you hear the abs working but it not stop you feel the pulse without the break or abs light coming on. I can unhook the abs and my breaks work ok. I have changed the rear calibers and the front abs switches and don't know where to go from here.

This is a common problem with these trucks. You will need to set-up an appointment with the service Dept. at the dealership. There is an update for the ABS system. The function of this update is to reduce the sensitivity. When you get down to five MPH (with the brake applied) the ABS turns on (no light on dash) and you get the sensation of Sliding (braking is reduced).
This is assuming that the tires are the same size and pressure, And that there are no defects in the wheel speed sensors. Good-luck and please let me know what you decided to do and how it went.

SOURCE: ABS problem with GMC 2002 Sierra

its a low speed abs activation the problem is in the front sensors they need to be cleaned or replaced they [or one] probably has some corrosion on the sensor --[the 99 chevy tahoes had a limited recall over this issue and the fix was to remove and clean the abs sensor or if to corroded replace ] this problem doesnt set off an abs code or trouble light also sometimes the abs will activate by itself at under 4 mph without even touching brake

id check your caliper to see if the piston is compressing all the way if not check your fluid it should be clean not brown or if you have been through large amounts of water if it has gotten into the brake system and check your bleeder valve to check if it has rotted or come lose or if you have a break in the lines or air, most likely your caliper is failing to compress.

There was a TSB on this issue with your Sierra, a faulty or dirty ABS sensor is the cause of this problem. The fix is simple, just clean the ABS sensor at the front hub with brake parts cleaner and inspect the wire leads. At worst you may have to replace the sensor it self. Good luck

Brake pedal vibrates while braking and doesent stop right away


There's speed sensors at each wheel. You may have got some contamination in front of one of them... sounds like the abs is trying to compensate for un equal speed at each wheel... and something may be blocking a proper read at one of the wheels...

02 gmc sierra 2500, hard to stop


The pulsating is the ABS system. It's actually pumping the brakes incredibly fast to even the braking to all wheels.
There's sensors at each wheel and anytime it senses uneven braking, it's going to do this. You may want to pull the wheels and check the sensors and all of the connections and make sure there is no debris in any of the wheel sensor areas..

2002 camry breaks


take off brake caliper, take off your brake pads. check the sliders. sliders are on the side of the bracket. see if they are moving freely in and out. im pretty sure they are seized. that's why your pedal is soft and sinks down really fast when applied.
