Manual Bleeding

NOTE: DO NOT allow master cylinder to run dry during bleeding. NEVER reuse brake fluid that has drained from brake system. When bleeding disc brakes, air may tend to cling to caliper walls. Lightly tap caliper while bleeding to aid in removal of air.
  1. Bleed master cylinder first if necessary. Attach bleeder hose to right rear wheel cylinder and submerge end of hose in container partially filled with clean brake fluid. Loosen fitting about 3/4 turn and slowly depress brake pedal fully. Close bleeder and release brake pedal.
  2. Repeat until fluid is free of air bubbles. Repeat process following proper bleeding sequence. See BLEEDING SEQUENCE  . After completing bleeding procedure, ensure brake pedal is firm.
