Question

technician a replaces the pads if the linings are less than 1/8 inch (3.175 mm). technician b says if the pad on one side of the caliper is worn more than the other side, the rotor has excess runout and must be replaced. who is correct?
select one:
a. a only
b. b only
c. both a and b
d. neither a nor b
clear my choice

Explanation:

• Technician A: Brake pad linings less than 1/8 inch (3.175 mm) should be replaced. This is a standard rule in automotive maintenance.
• Technician B: Uneven pad wear is more likely due to a sticking caliper piston or slider pin rather than rotor runout. Rotor runout would cause other symptoms like vibration during braking, not just uneven pad wear.

Answer:

a. A only
