The teacher demonstrates the proper way to measure a brake rotor with the micrometer.

The teacher demonstrates the proper way to use a dial indicator to check the rotor for excessive runout.

The teacher demonstrates how to measure the brake drum with the drum brake micrometer.

The teacher demonstrates to students the proper and detailed procedure to check the hydraulics system for leaks.

The students get in groups of two and measure the brake rotor and brake drum. Here is a great opportunity for peer teaching, as students may assist each other. Each student takes turns with the measurements with the supervision of the teacher.
