Question

New front brake pads are 0.375 in. thick. The average wear rate of these pads in a particular vehicle is 0.062 in. per 15,000 mi. Determine (a) the expected wear after 60,000 mi and (b) the expected pad thickness after 45,000 mi.

Expert Solution
Step 1

a.) 

As per question average wear rate=0.062/15000 inch/mile

So wear after 60000 miles

Expected wear=0.06215000×60000 inch                       =0.248 inch.
