1994 GMC Sierra 1500 2wd LTE
I have no clue whats causing it, but the rear of my truck bounces when im braking from 45 or over. The peddle also pulsates when this happens. Any ideas?
1994 gmc sierra 1500 2wd. That brings up another point. my abs light has been on since the day i bought it. Never figured out whats caused it.... Well... Untill I made this thread atleast.Welcome to the Forum. Let’s start with your truck info. Pedal pulsing is usually indicative of an operating anti-lock braking mechanism.
Since you have a ABS light, one or both of the wheel sensors are bad. When applying the brakes, the ABS doesn't see any pulses from the sensor so it is assumed it is locked up, thus the ABS engages. It sits somewhere near the rear wheel bearings and they are threaded into the axle housing. It uses the bearing or the axle splines as a reluctor. It is a relatively inexpensive part and an easy job to do. Before going nuts into other fixes, replace both of them. At the auto parts store. have them scan for codes. It will show which wheel is the problem.I have no clue whats causing it, but the rear of my truck bounces when im braking from 45 or over. The peddle also pulsates when this happens. Any ideas?
