Which maintenance or inspection point is specific to ABS-equipped brakes?
- A.ABS parts never need inspection if the lamp is off today
- B.Sensor wiring, tone rings, connectors, and warning lamps should be intact and free of damage or heavy contamination
- C.Wheel sensors should be disconnected in winter
- D.The foundation brakes no longer need adjustment checks
Correct answer
B. Sensor wiring, tone rings, connectors, and warning lamps should be intact and free of damage or heavy contamination
Why
The controller can only protect wheels it can measure, so damaged sensor leads or rings can disable that control. ABS inspection adds to, and never replaces, normal checks of linings, chambers, and adjustment.
