Pressure Bleeding

NOTE: NEVER reuse brake fluid that has drained from brake system. Ensure bleeder tank has sufficient fluid to complete bleeding procedure. DO NOT exceed 50 psi of pressure in tank.
  1. Release vacuum from booster by depressing brake pedal several times. Bleed master cylinder first if necessary. Clean master cylinder cap and surrounding area. Remove cap. With pressure tank at least 1/2 full, connect to master cylinder with adapters. Attach bleeder hose to right rear wheel cylinder.
  2. Place other end of hose in clean container partially filled with clean brake fluid so end of hose is submerged in fluid. Open release valve on pressure bleeder. Follow equipment manufacturers pressure instructions unless noted below.
  3. Unscrew bleeder valve 3/4-1 turn noting fluid flow. When fluid flowing from cylinder to jar is free of bubbles, close bleeder valve securely. Repeat process following proper bleeding sequence. See BLEEDING SEQUENCE  .
