Operation Description:

Your technician will remove the rear wheels to get to your brakes. The drums are removed and cleaned. If the two main adjustments that affect rear brake shoe operation are not set correctly, brake rotor “hot-spotting”, surface cracks, brake pad wear, or surface “glazing” can develop. Both the rear brake shoes and parking brake need to be adjusted. Rear brake shoe adjustment puts the brake shoes in the roper relationship to the brake drums. Rear brake shoes should be inspected and manually adjusted or serviced at routine vehicle maintenance intervals. Parking brake adjustment makes the vehicle’s parking brake operate within the intended range of the actuator (food pedal or hand lever) movement. Its adjustment should be checked when brake shoes are replaced and at routine vehicle maintenance intervals as well.

 

Significance:

This is about safety. Many vehicles still come equipped with front disc and rear drum systems. While rear brakes only handle about 25% of the braking load, they’re still a very important piece of your braking system.

 

Advantage:

When you apply the brakes, brake fluid is forced under pressure into the wheel cylinder, which in turn pushes the brake shoes into contact with the machined surface on the inside of the drum. When the pressure is released, return springs pull the shoes back to their rest position. As the brake linings wear, the shoes must travel a greater distance to reach the drum. A properly maintained braking system allows you to better control your stopping.
