Rear Brake Hose Replacement Disc

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

  3. Object Number: 179306  Size: SH
  4. Clean dirt and foreign material from the brake hoses and fittings.
  5. Use a backup wrench on the hose fitting in order to remove the brake pipe from the brake hose.
  6. Do not bend the brake pipe or the bracket.

  7. Remove the retainer clip from the brake hose at the hose mounting bracket.
  8. Remove the hose from the bracket.

  9. Object Number: 176035  Size: SH
  10. Remove the following items from the caliper:

Installation Procedure


    Object Number: 176035  Size: SH
  1. Install the following items to the caliper:
  2. • The brake hose bolt (1)
    • The hose (2)
    • The two new washers (4)

    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. With the weight of the vehicle on the suspension, install the brake hose into the bracket.

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

  7. Install the retainer 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 rear tire and the rear wheel. Refer to Tire and Wheel Removal and Installation in Tires and Wheels.
