Do brake shoes automatically adjust?

Automatic adjusters work from the handbrake or footbrake. Each time the brake is applied a lever turns a ratchet wheel and adjusts the brake shoes.

Where are brake shoe adjustments located?

What is brake clearance?

Achieving the optimum running clearance between the brake pad and disc will help avoid overheating. Brakes can overheat for a number of reasons. One of the most common, and most easily solved is the incorrect setting of the running clearance between the brake pad and disc.

Should there be a gap between brake pads and rotors?

make sure your brake pads are fresh, inside and out, front and rear. the gap between the pads and the rotor should be minimal as they do not need to open any further for the wheel to rotate.

As the car is moving in reverse and you step on the brakes, the shoes expand.

How do I adjust my brake pedal?
