Bench Bleeding The Mast Cylinder
NOTE: "Bench bleeding" (removing air from the master cylinder) must be completed BEFORE the replacement unit is installed in the
vehicle. Otherwise, the brake pedal will be insufficient and THE WARRANTY WILL BE VOID!
1.) Position the replacement master cylinder in a vise so that the jaws clamp onto the mounting flange. DO NOT TIGHTEN THE VISE
JAWS ON THE MASTER CYLINDER BODY! This will cause damage and void the warranty.
2.) Install brake failure warning switch and proportioning valve, if so equipped, onto the replacement master cylinder BEFORE bench
bleeding the unit. Use the new o-rings supplied with the replacement unit on the valves and switch. Install plugs in the proportioning
valve ports, if so equipped, before bench bleeding.
3.) Install bleeder tubes, if available, into the brake line outlet ports or use plugs to seal the ports.
4.) Add enough clean brake fluid to the reservoir so that the bleeder tube ends are submerged beneath the fluid level.
5.) Use a wooden dowel or similar tool to slowly push the master cylinder piston in about one inch, then release the piston slowly.
CAUTION:
Be careful to avoid spraying brake fluid! Keep your face away from the open reservoir.
6.) Wait 15 seconds and repeat step 5 until you no longer see air bubbles in the reservoir.
7.) Replace the reservoir cover. Do not remove bleeder tubes from the brake line fittings yet.
NOTE: Some fluid around the mouth of the piston bore is normal and does not indicate leakage. This is a rust inhibitive bore lubricant
used during assembly.
