Disc brakes are 24% of the ASE A5 exam — the biggest module after hydraulics — and the one where measurement separates the technicians from the guessers. This workbook drills Area 3 page by page alongside the free ASE Prep Lab Module 3 course on YouTube.

Print a page, watch the lesson, write as you go: how the square-cut seal really retracts a caliper, the pad wear atlas, a rotor measurement worksheet that works the machine-or-replace call with real micrometer numbers, the runout chain that turns a skipped measurement into a pulsation comeback, caliper service and the three piston-retraction personalities — then prove it in a six-case diagnosis lab.
