- Inspect the lines and hoses in a well lighted area. Use a small mirror to allow you to see concealed parts of the hose or line. Check the entire length and circumference of each line or hose.
- Look for any sign of wear, deformation, corrosion, cracking, bends, swelling or thread damage.
- The slightest sign of leakage requires immediate attention.
- Check all clamps for tightness and check that all lines and hoses have sufficient clearance from moving parts and heat sources.
- Check that any lines passing through grommets pass through the center of the grommet and are not forced against the side of the hole. Relieve any excess tension.
- Some metal lines may contain spring-like coils. These coils absorb vibration and prevent the line from cracking under strain. Do not attempt to straighten the coils or change their diameter.
REMOVAL & INSTALLATION
See Figures 1, 2 and 3
- Elevate and safely support the vehicle.
- Remove the wheel.
- Clean all dirt from the hose junctions.
- Place a catch pan under the hose area.
- Using 2 wrenches, disconnect the flexible hose from the steel brake line at the strut assembly.
- If equipped with disc brakes, disconnect the brake hose union bolt at the brake caliper. If equipped with drum brakes, disconnect the hose from the steel pipe running to the wheel cylinder.
- Remove the hose retaining clips and remove the hose from the vehicle.
- If the system is to remain disconnected for more than the time it takes to swap hoses, tape or plug the line and caliper to prevent dirt and moisture from entering.
- Install the new brake hose into the retaining clips.
- Connect the hose to the caliper (disc brakes) and tighten the union bolt to 22 ft. lbs. or connect the hose to the short line running into the wheel cylinder and tighten the fitting to 11 ft. lbs.
- Connect the steel brake line to the hose at the strut. Start the threads by hand and make sure the joint is properly threaded before tightening. Tighten the fitting to 11 ft. lbs.
- Install the wheel.
- Bleed the brake system.
- Lower the car to the ground.
