Brake Motor Pack (ABS)

ABS Brake Modulator/Master Cylinder Assembly Components:

DISASSEMBLE
1. Remove gear cover.
2. Four Torx(R) head screws attaching Antilock Brake System (ABS) brake motor pack.

Important:
^ Use care when handling the motor pack to ensure the motor pack connectors are not damaged, or accidental intrusion of brake fluid into the motor pack does not occur. This may result in a premature failure of the motor pack.
^ Take care in handling the motor packs. If dropped or damaged during handling, the motor packs must be replaced.

3. Remove the motor pack assembly.

Important:
^ If disassembly of the brake modulator/master cylinder assembly was due to an ABS hydraulic functional test that did not pass, the Automated ABS brake motor pack Diagnosis Test described should be performed at this time to isolate the ABS brake motor pack or brake modulator.
^ No repair of the motor pack is authorized. Replace as an assembly.

ASSEMBLE

Gear Position:

1. With the brake modulator upside down, and the gears facing you, rotate each ABS brake modulator gear counterclockwise until movement stops. This procedure will position the pistons on the ABS brake modulator very close to the top of the modulator bore. This will simplify the brake bleeding procedure.
2. Motor pack to brake modulator assembly.

Important:
^ Take care in handling the motor packs. If dropped or damaged during handling the ABS brake motor pack must be replaced.
^ Align each of the three ABS brake motor pack pinions with the brake modulator gears.

3. Four Torx(R) head screws.
- Tighten Torx(R) head screws to 4.5 Nm (40 ft. lbs.).
4. Gear cover to ABS brake modulator/brake master cylinder assembly.
