Pressure Bleeding
- Clean master cylinder cap and surrounding area. Remove cap. With pressure tank at least 1/2 full of specified fluid and charged at 10-30 psi (.7-2.0 kg/cm2 ), use adapters to connect tank to master cylinder. Follow equipment manufacturer's pressure instructions.
- Open pressure bleeder valve. Bleed master cylinder primary and secondary hydraulic lines individually. Put shop towels in place to catch brake fluid.
- Open lines. Allow brake fluid to flow out until all air is purged. Close bleed fitting and hydraulic line. Close pressure bleeder valve. Attach rubber drain hose to first wheel cylinder bleeder valve to be serviced. See Figure. See BLEEDING SEQUENCE table under BLEEDING SEQUENCE.
- Place other end of hose in clean glass jar partially filled with clean brake fluid so end of hose is submerged in fluid. Open pressure bleeder valve. Open bleeder fitting. Close bleeder fitting when fluid flow is free of bubbles. Repeat procedure on remaining wheel cylinder and calipers in sequence. See BLEEDING SEQUENCE table under BLEEDING SEQUENCE.
- When bleeding operation is complete, close pressure bleeder valve, and remove tank hose from adapter fitting. Check brake pedal operation. Ensure master cylinder is full of fluid.
CAUTION:
DO NOT exceed 50 psi (3.5 kg/cm2
) during bleeding.
