Manual Bleeding

  1. 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.
  2. Fill master cylinder, then install clear vinyl bleeder hose onto 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 clear glass jar.

3) Partially fill jar with clean brake fluid, so end of hose is submerged in fluid. Open bleeder valve 1-2 turns. Depress brake pedal slowly through its full travel.

4) Close bleeder valve, then release pedal. Pump pedal several times to push air toward wheel cylinders. Repeat procedure until flow of brake fluid is clear, and shows no signs of air bubbles. Proceed to next bleeder valves.

NOTE: Check fluid level in master cylinder frequently during the bleeding sequence.
