Use of any brake fluid other than approved DOT 3 will cause permanent damage to brake components and will render the brakes inoperative. Failure to follow these instructions may result in personal injury.
Brake fluid contains polyglycol ethers and polyglycols. Avoid contact with eyes. Wash hands thoroughly after handling. If brake fluid contacts eyes, flush eyes with running water for 15 minutes. 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.
Do not allow the brake master cylinder reservoir to run dry during the bleeding operation. Keep the brake master cylinder reservoir filled with the specified brake fluid. Never reuse the brake fluid that has been drained from the hydraulic system.
Brake fluid is harmful to painted and plastic surfaces. If spilled, wipe up immediately before damage to the painted or plastic surfaces occurs.
When any part of the hydraulic system has been disconnected for repair or installation of new components, air can get into the system and cause spongy brake pedal action. This requires bleeding of the hydraulic system after it has been correctly connected.
If the hydraulic control unit (HCU) or any component upstream of the HCU are installed new, carry out the brake system bleed procedure first without the diagnostic tool, followed by the brake system bleed procedure using the diagnostic tool. This reduces the risk of trapping air in the HCU.
- Before servicing the vehicle, refer to the Precautions section.
- Connect the diagnostic tool DCL cable adapter into the vehicle data link connector (DLC) under the dash and follow the diagnostic tool instructions.
- Clean all dirt from and remove the brake master cylinder filler cap and fill the brake master cylinder reservoir with clean motor vehicle brake fluid.
- For ABS vehicles only, open the master cylinder bleed screw until clear, bubble-free fluid flows from the tube into the cup.
- Bleed the brake system in the order displayed on the diagnostic tool or bleed from the longest to the shortest brake line. Place a box end wrench on the bleeder screw. Attach a rubber drain tube to the bleeder screw and submerge the free end of the tube in a container partially filled with clean brake fluid.
- Have an assistant hold firm pressure on the brake pedal.
Loosen the bleeder screw until a stream of brake fluid comes out. While the assistant maintains pressure on the brake pedal, tighten the bleeder screw.
Repeat 3 times until clear, bubble-free fluid comes out.
- Tighten the bleeder screw.
- Repeat Steps 3, 4, 5 and 6 for the remaining bleeder screws in the system.
