Gm has tech service bulitens on this issue.First the abs sensors can and should be removed,inspect the sensor mounting surface for rust (clean w/ sandpaper) insp the sensor (note the sensor may break w/ trying to remove so be gentlel) if all looks ok reassemble and test drive. if unwanted abs still persists both hub bearings should be replaced (call your dealer and ask if a special policy exsits for this condition) usually no abs code w/ be present Good luck Ray..

I'm no guru on ABS, but I don't know that a code will be displayed for a wheel bearing. Usually those sensors are related to the ABS system. I'd get a second opinion on the wheel bearing before paying to have that repair done. I'm not familliar with carx, but I'd be careful they aren't simply resetting a control and charging you for a wheel bearing.

Reset abs light pajero


When the ABS comes into play from heavy braking you will feel a pulsating of the brake pedal under your foot. This is the brake pressure, on off on off as the wheels stop start stop etc. The ABS will not control the vehicle direction but by allowing the wheels to turn under brakes and not lock up you have control of the steering and the direction the vehicle goes.The ABS will not stop you quicker and in fact on ice or loose surface the distance to stop will be increased. As I said all the ABS does is give you steering ability under brakes.. Take the vehicle to an accredited brake shop and have the ABS tested if you feel that it is no operating properly

When braking on my '04 Suburban, it pulsates like it has a warped brake rotor, but rotors are true (all four), and there is no correlating pulsation in the brake pedal, nor in the steering. Also, this...


Try pulling the fuse for the anti-lock braking system. If the problem goes away with the ABS disabled, check the wheel rotation sensors for problems, especially cracked or broken mounts or wiring issues. I'm thinking a sensor is dropping out when it gets heated by the brake and feeding bad data to the controller. The controller than treats it as a low traction situation and starts pulsing the brakes. If this is the case, you would see an ABS or Low Traction warning light on your dash.

Another possibility is a worn or loose suspension component oscillating under braking stress. In particular, check the shock absorber mounts. You could also have a pad that chatters instead of gripping the rotor cleanly - this may leave marks on the rotor, and would probably produce an audible noise.

I have 2002 silverado, the brake pedal pulsates and pushes back as the vehicle is slowing to a stop.I replaced the pads and rotors and the p loblem still exists. I now believe this isABS related.


Hello. What you are experiencing with the pulsating brakes and the brake pedal pushing back is the antilock brake system [ABS] working correctly. Joe

Thanks for choosing Fixya!

ABS brakes not working


If you can feel the pedal pulsating and the light turns on the Abs is doin its job. if you want a better stop you could try a brake pad upgrade to ceramic pads and for even more stoping power add an after market drilled and sloted rotors.

Abs light coming on , turn key off and it goes back out ?


depends if it just a rear abs or all four abs system. check the rear end on top of the diff there will be a wires coming off it. then the fronts you have to remove the wheels and follow the wire that goes to back of the rotors, and speeking of rotors, get your rotors machined if there is room or just replace them. there warped if your feeling the brake pedal pulsate or the car

Brakes pulsate real hard


That is just the ABS system at work. It is supposed to prevent your wheels from locking which often makes the brake pulsate, especially in wet weather or or snow or ice. The only way to really stop this is to disable to ABS by unplugging it and removing the fuse. This will make the ABS light appear in your dash, but your brakes will stop pulsating.
