Question

uneven disc brake pad wear is being discussed. technician a says the caliper piston may be stuck. technician b says the caliper may be stuck on the slides and unable to \float.\ which technician is correct?
technician a only
technician b only
both technicians
neither technician
question 2
1 pts
a \chirping\ noise is heard while the vehicle is moving forward, but stops when the brakes are applied. technician a says that the noise is likely caused by the disc brake pad wear sensors. technician b says the noise is likely a wheel bearing because the noise stops when the brakes are applied. which technician is correct?
technician a only
technician b only
both technicians
neither technician

Explanation:

Question 1 (Uneven disc brake pad wear)

• A stuck caliper piston (Technician A) can cause uneven pressure on brake pads, leading to uneven wear.
• A caliper stuck on slides (Technician B) means it can't float, so brake pads won't apply evenly, causing uneven wear. Both issues relate to caliper function affecting pad wear.

• Disc brake pad wear sensors (Technician A) chirp when pads are worn, and braking presses pads, stopping the sensor - induced noise.
• A wheel bearing (Technician B) noise typically doesn't stop when brakes are applied, so Technician B is incorrect. Only Technician A is correct.

Answer:

Both technicians

Question 2 (Chirping noise while moving, stops on braking)
