Removal Procedure
- Apply the park brake and block the wheels.
- Disconnect the electrical commector from the fluid level sensor.
- Use needle nose pliers in order to compress the locking tabs at the opposite side of the master cylinder.
- Remove the fluid level sensor (1).
- Disconnect the brake pipes from the master cylinder.
- Plug the open brake pipe ends.
- Remove the master cylinder mounting nuts.
- Remove the master cylinder from the vehicle.
- Drain the master cylinder reservoir of all brake fluid.
Notice: Avoid spilling brake fluid onto painted surfaces, electrical connections, wiring, or cables. Brake fluid will damage painted surfaces and cause corrosion to electrical components. If any brake fluid comes in contact with painted surfaces, immediately flush the area with water. If any brake fluid comes in contact with electrical connections, wiring, or cables, use a clean shop cloth to wipe away the fluid.
Important: Install a rubber cap or plug to the exposed brake pipe fitting ends in order to prevent brake fluid loss and contamination.
Installation Procedure
- Bench bleed the master cylinder. Refer to Master Cylinder Bench Bleeding .
- Install the master cylinder to the vehicle.
- Install the master cylinder mounting nuts.
- Connect the brake pipes.
- Install the fluid level sensor (1) to the master cylinder reservoir. Ensure the locking tabs secure the sensor to the reservoir.
- Connect the electrical connector to the fluid level sensor.
- Bleed the hydraulic brake system. Refer to Hydraulic Brake System Bleeding .
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.
Tighten
Tighten the master cylinder mounting nuts to 36 N·m (27 lb ft).
Tighten
Tighten the brake pipe fittings to 17 N·m (13 lb ft).
