Pressure Bleeding
NOTE:
The use of ABS Bleeder Box Adapter (T90P-50-ALA) and Jumper Cable (T93T-50-ALA) is required in conjunction with pressure bleeding, to bleed system when Hydraulic Control Unit (HCU) is replaced.
- Clean master cylinder cap and surrounding area. Remove cap. With pressure tank at least 1/2 full of specified brake fluid and charged between 10-30 psi (.7-2.0 kg/cm2
), use adapters to connect tank to master cylinder. Follow equipment manufacturer's pressure instructions.CAUTION: Never exceed 50 psi (3.5 kg/cm2 ) during bleeding.
- Open pressure bleeder valve. Attach one end of rubber drain hose to master cylinder bleeder fitting. Open bleed fitting. Use shop towels to catch brake fluid.
- Open lines and 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 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 .
- 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.
