|
By the end of the course, students will: |
|
|
(A) |
Remove, clean (using proper safety procedures), inspect, and measure brake drums; service or replace as needed. |
| |
(B) |
Mount brake drum on lathe; machine braking surface. |
| |
(C) |
Clean, inspect, and measure rotor with a dial indicator and a micrometer; follow manufacturer's recommendations in determining need to machine or replace. |
| |
(D) |
Refinish rotor according to manufacturer's recommendations. |
| |
(E) |
Inspect and test anti-lock brake systems (ABS) components; determine necessary action. |
| |
(F) |
Diagnose poor stopping, wheel lock-up, abnormal pedal feel or pulsation, and noise concerns caused by the anti-lock brake system (ABS), determine necessary action. |
| |
(G) |
Diagnose anti-lock brake system (ABS) electronic control(s) and components using self-diagnosis and/or recommended test equipment; determine necessary action. |
| |
(H) |
Depressurize high-pressure components of the anti-lock brake system (ABS). |
| |
(I) |
Bleed the anti-lock brake system's (ABS) front and rear hydraulic circuits. |
| |
(J) |
Remove and install anti-lock brake system (ABS) electrical/electronic and hydraulic components. |
| |
(K) |
Service, test, and adjust anti-lock brake system (ABS) speed sensors. |
| |
(L) |
Diagnose anti-lock brake system (ABS) braking concerns caused by vehicle modifications (tire size, curb height, final drive ratio, etc.). |
| |
(M) |
Test pedal free travel with and without engine running; check power assist operation. |
| |
(N) |
Check vacuum supply (manifold or auxiliary pump) to vacuum-type power booster. |
| |
(O) |
Inspect the vacuum-type power booster unit for vacuum leaks; inspect the check valve for proper operation; determine necessary action. |
| |
(P) |
Inspect and test hydro-boost system and accumulator for leaks and proper operation; determine necessary action. |
