Question

1. why is it important to clean and lubricate the caliper pins and bushings?

○ to keep the pads from squeaking on application
○ to make sure the caliper can apply and release correctly
○ to prevent the caliper piston from binding during application
○ to prevent the pads from sticking in the bracket

Explanation:

• Cleaning and lubricating caliper pins and bushings ensures smooth movement of the caliper. The caliper's function is to apply (clamp the brake pads onto the rotor) and release (move back to allow the rotor to spin freely) during braking. If the pins and bushings are dirty or lack lubrication, the caliper may not move as intended, affecting its ability to apply and release.
• Option A: Squeaking of pads is more related to pad material or lack of anti - squeal measures, not pin/bushing cleaning/lubrication.
• Option C: Caliper piston binding is related to piston seals or cylinder issues, not pins/bushings.
• Option D: Pads sticking in the bracket is about pad - bracket fit or debris in the bracket, not pins/bushings.

Answer:

B. To make sure the caliper can apply and release correctly
