Brake System Bleeding










Manual

WARNING: Do not use any fluid other than clean brake fluid meeting manufacturer's specification. Additionally, do not use brake fluid that has been previously drained. Following these instructions will help prevent system contamination, brake component damage and the risk of serious personal injury.

WARNING: Carefully read cautionary information on product label. For EMERGENCY MEDICAL INFORMATION seek medical advice. For additional information, consult the product Material Safety Data Sheet (MSDS) if available. Failure to follow these instructions may result in serious personal injury.

WARNING: Do not allow the brake master cylinder to run dry during the bleeding operation. Master cylinder may be damaged if operated without fluid, resulting in degraded braking performance. Failure to follow this instruction may result in serious personal injury.

NOTICE: Do not spill brake fluid on painted or plastic surfaces or damage to the surface may occur. If brake fluid is spilled onto a painted or plastic surface, immediately wash the surface with water.

NOTE: The Hydraulic Control Unit (HCU) bleeding procedure must be carried out if the HCU or any components upstream of the HCU are installed new.

NOTE: Pressure bleeding the brake system is preferred to manual bleeding.

1. Clean all dirt from and remove the brake master cylinder filler cap and fill the brake master cylinder reservoir with clean, specified brake fluid.





2. Remove the bleeder screw cap and place a box-end wrench on the RH rear bleeder screw. Attach a rubber drain hose to the RH rear bleeder screw and submerge the free end of the hose in a container partially filled with clean, specified brake fluid.





3. Have an assistant pump the brake pedal at least 3 times and then hold firm pressure on the brake pedal.

4. Loosen the RH rear bleeder screw until a stream of brake fluid comes out. While the assistant maintains pressure on the brake pedal, tighten the RH rear bleeder screw.
- Repeat until clear, bubble-free fluid comes out.

- Refill the brake master cylinder reservoir as necessary.

5. Remove the rubber hose and tighten the bleeder screw to specifications. For additional information, refer to Specifications.
- Install the bleeder screw cap.

6. Repeat Steps 2 through 5 for the LH rear, RH front and LH front bleeder screws in this order.
