Brake Bleeding: Service and Repair
Pressure
Pressure
WARNING: Use of any other than approved DOT 3 motor vehicle brake fluid will cause permanent damage to brake components and will
render the brakes inoperative. Failure to follow these instructions may result in personal injury.
^
WARNING: 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.
CAUTION: 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.
CAUTION: Brake fluid is harmful to painted and plastic surfaces. If brake fluid is spilled onto a painted or plastic surface, immediately wash it with
water.
NOTE: When any part of the hydraulic system has been disconnected for repair or new installation, air may get into the system and cause spongy
brake pedal action. This requires bleeding of the hydraulic system after it has been correctly connected. The hydraulic system can be bled manually or
with pressure bleeding equipment.
NOTE: Bleed the longest line first. Be sure the bleeder tank contains enough specified brake fluid to complete the bleeding operation.
1. Clean all dirt from and remove the brake master cylinder filler cap and fill the brake master cylinder reservoir with the specified brake fluid.
2. NOTE: Master cylinder pressure bleeder adapter tools are available from various manufacturers of pressure bleeding equipment. Follow the
instructions of the manufacturer when installing the adapter.
Install the bleeder adapter to the brake master cylinder reservoir and attach the bleeder tank hose to the fitting on the adapter.
3. Place a box-end wrench on the RH rear disc brake caliper bleeder screw. Attach a rubber drain tube to the RH rear disc brake caliper bleeder
screw and submerge the free end of the tube in a container partially filled with clean brake fluid.
4. Open the valve on the bleeder tank.
5. Loosen the rear disc brake caliper bleeder screw. Leave open until clear, bubble-free brake fluid flows, then tighten rear disc brake caliper bleeder
screw and remove the rubber hose.

Tighten to 16 Nm (12 ft. lbs.).
6. Continue bleeding the rest of the system, going in order from the LH rear disc brake caliper to the RH front disc brake caliper, ending with the LH
front disc brake caliper.
7. Close the bleeder tank valve and remove the tank hose from the adapter and remove the adapter.
