Master Cylinder Bleeding
STANDARD PROCEDURE - MASTER CYLINDER BLEEDINGCAUTION: 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 8822 includes ISO style flare adapters with metric threads to be used in conjunction with Bleeder Tubes, Special Tool Package 8358.
2. Attach special tools for bleeding master cylinder in the following fashion:
a. For non-ABS master cylinders, thread one Adapter, Special Tool 8822-2, into each outlet port. Tighten Adapters to 17 Nm (145 inch lbs.) torque.
b. For ABS master cylinders, thread one Adapter, Special Tools 8822-2, into the primary outlet port and one Adapter, Special Tool 8822-1, into the secondary outlet port. Tighten Adapters to 17 Nm (145 inch lbs.) torque.
c. Thread one Bleeder Tube, Special Tool 8358-1, into each Adapter. Tighten each tube to 17 Nm (145 inch lbs.) torque. Flex bleeder tubes and place open ends into mouth of fluid reservoir as far 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 Mopar Brake Fluid or equivalent conforming to DOT 3 specifications. Make sure fluid level is above tips of bleeder tubes in reservoir.
4. Using a wooden dowel as a pushrod , slowly depress master cylinder pistons, then release pressure, allowing 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 bleeding tubes. Plug outlets and install filler cap.
6. Remove master cylinder from vise and install on power brake booster.
