Currently driving a 04 5 Spd.SSM TL. When I brake to slow down on a smooth road, my brakes work fine. When i brake to slow down on a bumpy road, the brakes seem to slip and not have any grip, and the pedal vibes a lot. Anyone had a similiar problem or might know whats wrong? is this normal for the TL? any info, or advice is welcome. Thanks.

 

Nothings wrong, its just how it's supposed 2 be dont be going to fast over a bumpy road anyways.

ABS activated causing the brake pedal vibration.
