Rear brake hose is bad

  • 131,000 MILES
Where the rear brake pads and rotors are only a little over a year old. Upon a routine check for a spongy bake pedal, the test drive mechanic came back and informed me that the rear brake hose is bad.
Do you
have the same problem?

When the hoses get older, they can dry rot and crack creating a leak. This can cause brake failure if the hose totally breaks. Here are videos to help you make your own line or replace the brake flex hose.


The process is the same in most cases.

Here are the directions specific to your vehicle for replacement. The attached pics correlate with the directions.

Removal Procedure

Caution: Refer to Brake Fluid Irritant Caution in Service Precautions.

Notice: Refer to Brake Fluid Effects on Paint and Electrical Components Notice in Service Precautions.

1. Raise and suitably support the vehicle.
2. Remove the front tire and wheel assembly.
3. Clean all dirt and foreign material from the brake hoses and brake pipe fitting.

4. Important: Install a rubber cap or plug to the exposed brake pipe fitting end to prevent brake fluid loss and contamination.

Use a backup wrench on the hose fitting, disconnect the brake pipe fitting from the brake hose, then cap or plug the brake pipe fitting end.Do not bend the brake pipe or the bracket.
5. Remove the brake hose retaining clip from the hose mounting bracket.
6. Remove the hose from the bracket.
