Removal

1. Disconnect negative (ground) cable from the battery and isolate cable.

PDC Attachment To Thermogaurd:

2. Remove the Power Distribution Center (PDC) from the battery thermogaurd. PDC is removed by unlatching the two retaining clips holding it to the thermogaurd and then pulling it straight up off of the thermogaurd.

Speed Control Servo Bracket Mounting:

3. Remove vacuum supply hose from speed control servo.
4. Remove the 2 bolts mounting the bracket for the speed control servo to the body.

Wiring Harness Connection To Speed Control Servo:

5. Remove the wiring harness connector from the speed control servo. Then remove the routing clip for the speed control servo wiring harness from the speed control servo mounting bracket.
6. Lay the speed control servo, with the speed control cable attached, on top of the engine.
7. Disconnect wiring harness connector from the brake fluid level sensor on master cylinder reservoir.

ICU Mounting Location:

8. Disconnect primary and secondary brake tubes from master cylinder. Install plugs at brake tube outlets of master cylinder assembly.
9. Clean the area where the master cylinder attaches to the vacuum booster using a suitable brake cleaner such as Mopar Brake Parts Cleaner or an equivalent.

CAUTION: On ABS equipped vehicles, vacuum in power booster must be pumped down before removing master cylinder to prevent the booster from sucking in any contamination. This can be done simply by pumping the brake pedal, with the engine not running, until a firm brake pedal is achieved.

Master Cylinder Mounting:

10. Remove the 2 nuts attaching master cylinder to power brake booster unit.
11. Slide the master cylinder straight out of the vacuum booster unit.

CAUTION: Do not apply a 12 volt power source to any terminals of the 25 HCU connector when disconnected from the Controller Antilock Brake (CAB).

Unlocked CAB Connector:

14. Disconnect the 26 way wiring harness connector from the CAB using the following procedure. Grasp the lock on the 25 way connector and pull it out from the connector as far as possible. This will unlock and raise the 25 way connector out of the socket on the CAB.
