Replace rear pads and discs

If your parking brake is not functioning properly, then perhaps it's time to replace your parking brake shoes. The parking brake shoes can only be inspected after the removal of the rear brake calipers and discs. You will need to safely raise and support the vehicle and remove the caliper and rotor to replace the brake shoes. Please see our articles on these procedures for additional information.

The parking brake shoes are located under the bell of the rear brake rotors (red arrows).
Figure 1

The parking brake shoes are located under the bell of the rear brake rotors (red arrows). You will need to remove both the caliper and rotor to change them.

With the rotor off you can see the adjuster on the top of the assembly that you use to adjust the pads as they wear down (red arrow).

There are two retaining springs (red arrow, one on each side) that help hold the shoes in place.

Spin the axle so you can get access to the springs through the flange (red arrow).

Spin the axle so you can get access to the springs through the flange (red arrow). Compress the springs and turn them to remove them from the assembly.

Remove one side of the lower spring by the separator (yellow arrows).

With the top spring and tensioner attached, pull the shoes apart so you can get them over the axle and remove them.

With the top spring and tensioner attached, pull the shoes apart so you can get them over the axle and remove them. This is what the assembly should look like when you take it off.

Preassemble the new shoes so they look like picture 6.

Preassemble the new shoes so they look like picture 6. Stretch them over the axle flange and sit the lower part of the shoes in the expander grooves (green arrows).

Reinstall the lower spring and the two retaining clips.

Reinstall the lower spring and the two retaining clips. Make sure the tensioner is retracted all the way. Installation of the other components is the reverse of disassembly.
