MASTER CYLINDER BLEEDING

CAUTION: When clamping the master cylinder in a vise for bleeding, carefully tighten the vise just enough to hold the master cylinder from moving. Excessive pressure can damage the master cylinder.

1. Clamp master cylinder in a vise.

NOTE: The master cylinder outlet ports use ISO style flares and metric threads. Special Tool Package 8822A includes ISO style flare adapters with metric threads to be used in conjunction with Bleeder Tubes, Special Tool Package 8358A.










2. Attach special tools for bleeding master cylinder in the following fashion:
a. Thread Adapter (3), Special Tools 8822-1, into the primary outlet port. Tighten Adapter to 17 Nm (145 in. lbs.).
b. Thread Adapter (4), Special Tool 8822-2, into the secondary outlet port. Tighten Adapter to 17 Nm (145 in. lbs.).
c. Thread one Bleeder Tube (1), Special Tool 8358-1, into each Adapter. Tighten each tube to 17 Nm (145 in. lbs.) torque. Flex bleeder tubes and place open ends into mouth of fluid reservoir as far down as possible.

NOTE: Make sure open ends of bleeder tubes stay below surface of brake fluid once reservoir is filled to proper level to avoid ingesting air while bleeding.

3. Fill reservoir with brake fluid conforming to DOT 4 Mopar(R) Brake Fluid or equivalent. If DOT 4 is not available, DOT 3 is acceptable. Make sure fluid level is above tips of bleeder tubes in reservoir.









4. Using a wooden dowel (2), depress master cylinder pistons slowly, then allow pistons to return to released position. Repeat several times until all air bubbles are expelled. Make sure fluid level stays above tips of bleeder tubes in reservoir while bleeding.
5. Remove bleeder tubes (1) and adapters (3, 4) from master cylinder. Plug master cylinder outlets and install filler cap.

6. Install master cylinder on vehicle. Brake Master Cylinder - Installation
