GMC 2500 2×4
Engine Size: 6.0L
Issue / Question:
Sometimes my brakes feel like they are engaging even while under power. Also, sometimes I feel the surge of ABS. Tapping on the brake peddle seems to free the brakes. The problem is intermittent and only lasts a few minutes at a time. It’s also bad at stop signs. To take off with the brakes on feels like power braking.
There are several TSB’s on this. In many cases rust develops behind the speed sensors and the clearance is to close to the exciter rings causing the ABS to activate. Let us know if you want us to check it.
