Service brakes

30 reports2 crashes
“The brake vacuum pump has leaked a small amount of lubricating oil into the hose. This contamination resulted in a loss of power assist braking. The loss of power assist in braking has increased stopping distance and lead to a near vehicle crash. No indicator lights were present. Repair: Replacement of the brake vacuum line with one that contains a check valve, eliminating the possibility that oil will reach the brake booster; as well as the brake booster and brake master cylinder will also be replaced.”
