Master Cylinder Bleeding (Bench)

  1. Support brake master cylinder body in a vise, and fill both fluid brake master cylinder reservoirs with brake fluid. Install plugs in front and rear brake outlet ports. Bleed front brake system first. Loosen plug in front brake outlet port and depress primary piston slowly to force air out of master cylinder.
  2. Tighten plug while piston is depressed or air will enter brake master cylinder. Repeat procedure until no air bubbles are present. Repeat bleeding procedure for rear brake outlet port with front brake outlet plugged. Tighten plugs and try to depress piston. Piston will not depress if all air is out of master cylinder.
