Caution: Refer to Brake Fluid Irritant Caution in the Preface section.

Notice: Refer to Brake Fluid Effects on Paint and Electrical Components Notice in the Preface section.

1. Disconnect the electrical connector from the brake fluid level sensor.
2. Disconnect the brake pipes from the master cylinder.

Important: Install a rubber cap or plug to the exposed brake pipe fitting end in order to prevent brake fluid loss and contamination.

3. Plug the open brake pipe fitting ends.



4. Remove the 2 master cylinder mounting nuts.
5. Remove the master cylinder.
6. Remove the reservoir from the master cylinder if it is to be reused on a replacement master cylinder. Refer to Master Cylinder Reservoir Replacement .

1. Install the brake master cylinder reservoir to the master cylinder if it was removed previously. Refer to Master Cylinder Reservoir Replacement .
2. Bench bleed the master cylinder. Refer to Master Cylinder Bench Bleeding .



3. Install the master cylinder to the vacuum brake booster.

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.

4. Install the brake master cylinder mounting nuts.

Tighten
Tighten the brake master cylinder mounting nuts to 25 N·m (18 lb ft).

5. Remove the plugs from the brake pipes.
6. Install the brake pipes to the master cylinder.

Tighten
Tighten the brake pipe fittings at the master cylinder to 32 N·m (24 lb ft).

7. Connect the electrical connector to the brake fluid level sensor.
8. Bleed the hydraulic brake system. Refer to Hydraulic Brake System Bleeding .
