When they are used on a Corvette with out of spec rotors, spindles, loose bearings or a Corvette that is driven hard; they can actually suck air into the caliper fluid area causing a loss of brake pedal. This problem is called (by GM engineers) reverse air oscillation. Because of these problems, GM quit using lip seals in the 1982. O-Ringseals virtually elimina
