Question

how do you know when to replace the pads in your disc brakes?
after 3,000 miles
when you hear a squealing noise while braking
when the warning light on your dashboard comes on
when your tires are worn

Explanation:

• 3,000 miles is too low; brake pad lifespan varies widely (25,000-70,000 miles) based on driving habits.
• Squealing noise from brakes is a built-in wear indicator (a metal tab scraping the rotor) signaling pads are worn thin.
• Many vehicles have a dashboard warning light triggered by a sensor when pads reach minimum thickness.
• Tire wear is unrelated to brake pad condition.

Answer:

B. when you hear a squealing noise while braking
C. when the warning light on your dashboard comes on
