Caution: Brake fluid may irritate eyes and skin. In case of contact, take the following actions:

• | Eye contact--rinse thoroughly with water.

• | Skin contact--wash with soap and water.

• | If ingested--consult a physician immediately.

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.

3. Disconnect the brake pipes from the brake modulator assembly.
4. Disconnect the brake pipes (1,2) from the proportioning valve (3).
5. Remove the brake modulator assembly. Refer to Brake Pressure Modulator Valve Assembly Replacement in Antilock Brake System.

Important: The proportioning valve gasket (3) between the proportioning valve and the hydraulic modulator assembly (4) must be replaced whenever these components are separated.

6. Remove the brake proportioning valve (1) from the brake modulator assembly (4).

### Installation Procedure

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.

1. Install the brake proportioning valve (2) to the brake modulator assembly (4) using a new gasket.
