NHTSA recall 91V123000
Service brakes, hydraulic › Foundation components › Disc › Caliper
Chevrolet P3 and 1 more
The defect
Brakes may have missing rear axle outer bearing retaining ring and or greater than specified bearing end play. Either condition allows the rotor and hub assembly to shift position relative to the spindle. This movement can cause brake caliper piston recede farther than normal into the piston bore which would require greater than normal brake fluid displacement when the service brakes are applied.
The risk
This condition leads to increased stopping distance, andshould minimum stopping distance be required, it could result in an accidentwithout warning.
The remedy
Replace both rear axle hubs.
