1ST INCIDENT - WIFE EXITED HIGHWAY ONTO RAMP AND WHEN APPLYING BRAKES, VEHICLE SPUN AROUND AND RR WHEEL STRUCK CURB CAUSING $350 IN DAMAGES.

AFTER EXTENSIVE DIAGNOSIS AND REPLACEMENT OF MASTER CYLINDER AND 1 BRAKE CALIPER, IT WAS DETERMINED THAT THE BRAKE PROPORTIONING VALVE WAS FAULTY, SINCE AIR COULD NOT BE BLED FROM THE LF CALIPER.
