Notice: Hydraulic brake systems use two distinct and incompatible fluids. Power steering fluid is used in the hydraulic brake booster system. Brake fluid is used in the master cylinder and brake pipes. Use extreme care when selecting brake system fluids, or seal damage can result. Refer to General Information to select the correct fluid.

For information on checking and adding fluid to the hydraulic booster system, refer to Checking and Adding Power Steering Fluid in Power Steering System.

Refer to Power Steering System Bleeding in Power Steering System.

Refer to Power Steering System Flushing in Power Steering System.

1. Apply the parking brake.
2. Disconnect the inlet hose, the steering gear, and the return hoses from the booster assembly.
3. Remove the master cylinder. Refer to Master Cylinder Replacement
4. Remove the stoplamp switch and the pushrod.

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.

3. Install the booster to bulkhead nuts.

Tighten
Tighten the nuts to 36 N·m (26 lb ft).

4. Install the stoplamp switch and the pushrod.
5. Install the master cylinder. Refer to Master Cylinder Replacement
6. Connect the return hose, the steering gear, and the inlet hoses.
