Question

a brake inspection reveals that the outboard pad is significantly thinner than the inboard pad. technician a says the problem could be a defective dust boot that caused the caliper to seize. technician b says the problem could be caused by poor lubrication or deformation of the machined sliding areas on the caliper and/or anchor plate. who is correct?
select one:
○ a. a only
○ b. b only
○ c. both a and b
○ d. neither a nor b

Explanation:

• A defective dust boot can cause the caliper to seize. When the caliper seizes, it may not retract properly, leading to uneven wear (in this case, the outboard pad being thinner as it may be in more constant contact due to the seizure).
• Poor lubrication or deformation of the machined sliding areas on the caliper and/or anchor plate can also prevent the caliper from sliding freely. This lack of free movement can result in uneven pad wear (such as the described outboard - inboard pad thickness difference).

Answer:

C. both A and B
