Brake Bleeding: Service and Repair

WARNING: Brake fluid contains polyglycol ethers and polyglycols. Avoid contact with the eyes. Wash hands thoroughly after handling. If brake fluid contacts the eyes, flush the eyes for 15 minutes with cold running water. Get medical attention if irritation persists. If taken internally, drink water and induce vomiting. Get medical attention immediately. Failure to follow these instructions may result in personal injury.

CAUTION: Make sure that the vehicle is standing on a level surface or supported on a non-wheel free lift.

CAUTION: If brake fluid is split on the paint work, the affected areas must be immediately washed down with cold water.

CAUTION: Make sure the battery ground cable is disconnected on vehicles fitted with ABS.

NOTE: The system consists of separate circuits for each front and diagonally opposite rear wheel. Each front to rear circuit and each wheel circuit can be bled individually of each other.

NOTE: The service ABS hydraulic control unit (HCU) is supplied filled with brake fluid. Therefore, a conventional bleed procedure should be adequate to remove all air from the brake system. However, if air in the HCU is suspected, use the vehicle specific step-by-step NGS instructions.
