Notice: Brake fluid will damage electrical connections and painted surfaces. Use shop cloths, suitable containers, and fender covers to prevent brake fluid from contacting these areas. Always re-seal and wipe off brake fluid containers to prevent spills.

Important: The combination valve is not repairable. The combination valve must be replaced as an assembly.

1. Raise and suitably support the vehicle.

Caution: Unless directed otherwise, the ignition and start switch must be in the OFF or LOCK position, and all electrical loads must be OFF before servicing any electrical component. Disconnect the negative battery cable to prevent an electrical spark should a tool or equipment come in contact with an exposed electrical terminal. Failure to follow these precautions may result in personal injury and/or damage to the vehicle or its components.

2. Disconnect the negative battery cable.
3. Disconnect the electrical connectors.
4. Remove the hydraulic brake lines.
5. Plug the pipes in order to prevent loss of fluid or contamination.
6. Remove the bolts (8).
7. Remove the combination valve (9).

1. Install the combination valve (9).

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

2. Install the bolts.

Tighten
Tighten the 3 combination fastening bolts (8) to 8 N·m (71 lb in) and then to 12 N·m (106 lb in).

3. Connect the electrical connectors.
4. Connect the hydraulic lines.

Tighten
Tighten the hydraulic lines to 30 N·m (22 lb ft).

5. Lower the vehicle.
6. Connect the negative battery cable.
7. Bleed the brake hydraulic system. Refer to Hydraulic Brake System Bleeding .
