Removal Procedure

Caution: Do not move the vehicle until a firm brake pedal is obtained. Air in the brake system can cause loss of brakes with possible personal injury.

Notice: Do not allow components to hang from the flexible brake hoses as damage to the hoses may occur. Some brake hoses have protective rings or covers to prevent direct contact of the hose with other chassis parts. Besides causing possible structural damage to the hose, excessive tension could cause the hose rings to move out of their proper locations.

Notice: Brake hoses should not be crimped at any point, in order to prevent the loss of brake fluid from any component.

  1. Raise and suitably support the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.
  2. Remove the front tire and the front wheel. Refer to Tire and Wheel Removal and Installation in Tires and Wheels.
  3. Clean the dirt and foreign material from the brake hoses and fitting.

  2. • The brake hose bolt (4)
    • The hose (5)
    • The two new washers (3)
    • Use two new washers.

    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. Lubricate the bolt threads with brake fluid.
  4. Tighten
    Tighten the brake hose caliper bolt to 54 N·m (40 lb ft).

  5. Install the brake hose into the bracket.
  6. There should not be any kinks in the hose.

    Align the hose fitting with the notch in the bracket. Use the hose paint stripe as a visual aid.

  7. Install the retainer clip onto the hose fitting at the bracket.
  8. Connect the brake pipe to the brake hose:
  9. • Use a backup wrench on the hose fitting.
    • Do not bend the bracket or pipe.

    Tighten
    Tighten the brake pipe tube nut to 15 N·m (11 lb ft).

  10. Install the front tire and the front wheel. Refer to Tire and Wheel Removal and Installation in Tires and Wheels.
  11. Ensure that the hose does not make contact with any part of the suspension. Check the hose in extreme right and extreme left turn conditions. If the hose makes contact, remove the hose and correct the condition.
  12. Lower the vehicle.
  13. Bleed the brakes. Refer to Hydraulic Brake System Bleeding .
