Pressure Bleeding
WARNING:
Failure to release pressure slowly from reservoir will cause fluid spill and may result in injury and/or paint damage.
NOTE:
Use only diaphragm-type pressure bleeding equipment to prevent air, moisture and other contaminants from entering system.
- Ensure ignition remains in OFF position during brake bleeding procedure. Depressurize accumulator by pumping brake pedal at least 40 times. When a definite increase in pedal effort is felt, pump pedal a few more times to ensure pressure is released.
- Remove both reservoir caps. Install pressure bleeder adapter on one reservoir port and dummy cap on the other. Attach bleeding equipment to bleeder adapter per equipment instructions. Charge pressure bleeder to approximately 20 psi (1.4 kg/cm2 ).
- Connect transparent hose to LR caliper/wheel cylinder bleed screw. Submerge free end of hose in clear jar partially filled with clean brake fluid. With pressure bleeder turned on, open caliper/wheel cylinder bleed screw 1/2 - 3/4 turn, and allow fluid to flow into container. Leave bleed screw open until clear, bubble-free fluid flows from hose.
- When installing NEW components or, if master cylinder reservoir was drained or hydraulic assembly removed before bleeding, slowly pump brake pedal 2 times while bleed screw is open and fluid is flowing. This will help purge air from master cylinder and/or hydraulic assembly. Tighten caliper/wheel cylinder bleed screw to 80-170 INCH lbs. (9-19 N.m).
- Bleed calipers/wheel cylinders in the following order: LR, RR, LF and RF. After all calipers/wheel cylinders have been bled, release pressure bleeding equipment air pressure. Close pressure bleeder valve, and slowly unscrew bleeder adapter from hydraulic assembly reservoir. Remove bleeder adapter and bleeder equipment.
- Using a syringe, remove excess fluid from reservoir (to top of filter screen). Install reservoir caps, and turn ignition on to allow ABS pump to charge accumulator. Recheck fluid level.
