Removal Procedure

Caution: Do not move the vehicle until a firm brake pedal is obtained. Failure to obtain a firm pedal before moving vehicle may result in 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 .
  2. Remove the tire and wheel. Refer to Tire and Wheel Removal and Installation .

  3. Object Number: 179425  Size: MH
  4. Clean all the dirt and foreign material from the brake hoses and fittings.
  5. Remove the brake pipe from the brake hose at the bracket. Use a backup wrench on the hose fitting. Do not bend the brake pipe or bracket.
  6. Remove the retainer at the hose mounting bracket.
  7. Remove the hose from the bracket.
  8. Remove the following components from the caliper:
  9. • The brake hose caliper bolt
    • The brake hose
    • The two washers from the caliper
  10. Discard the two washers from the caliper.

Installation Procedure


    Object Number: 179425  Size: MH

    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 following components on the caliper:
  2. • The brake hose caliper bolt. Lubricate the bolt threads with brake fluid
    • The brake hose
    • Two new washers

    Tighten
    Tighten the brake hose caliper bolt to 44 N·m (33 lb ft).

  3. With the weight of the vehicle on suspension, install the brake hose into the bracket.
  4. • Ensure that there are no kinks in the hose
    • Use the hose paint strip as a visual aid
    • Align the hose fitting with the notch in the bracket
  5. Install the retainer onto the hose fitting at the bracket.
  6. Install the brake pipe to the brake hose. Use a backup wrench on the hose fitting. Do not bend the bracket or the pipe.
  7. Tighten
    Tighten the brake pipe tube nut to 15 N·m (11 lb ft).

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