Pressure Tank Bleeding
- On Isuzu and Jaguar models, start engine and run at idle. On all other models, exhaust all vacuum from power unit by depressing brake pedal several times.
- Clean the master cylinder cap and surrounding area, then remove cap. With pressure tank at least 1/3 full, connect tank to master cylinder using proper fitting adapter(s).
- Attach bleeder hose to first bleeder valve to be serviced.
NOTE:
On manual transmission vehicles where clutch master cylinder feeds from brake master cylinder, bleed clutch cylinder first.
See BRAKE LINE BLEEDING SEQUENCE table. Place other end of hose in a clean glass jar. Partially fill jar with clean brake fluid, until end of hose is submerged in fluid.
4) Open release valve on pressure bleeder. Unscrew bleeder valve 1-2 turns, noting fluid flow. When fluid flow into container is clear, and free of bubbles close bleeder valve securely.
5) Bleed remaining cylinders in correct sequence and in the same manner. Remove pressure tank from master cylinder and check fluid level of master cylinder reservoir.
