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 to prevent 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 rear tire and wheel. Refer to Tire and Wheel Removal and Installation in Tires and Wheels.

Installation Procedure


    Object Number: 179308  Size: SH

    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 hose bolt.
  2. Install the brake hose into the brackets.

    There should be no kinks in the hose.

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

    Tighten
    Tighten the Brake Hose bolt (1) to 54 N·m (40 lb ft).

  3. Use a backup wrench on the hose fitting in order to connect the brake pipe to the brake hose.
  4. Do not bend the bracket or the pipe.
  5. Tighten
    Tighten the tube nut to 15 N·m (11 lb ft).
