Q: Bumping noise when car brakes going downhill

asked by on

When I'm going downhill, there is a bumping noise when I brake. It happens mostly downhill, but less often on level ground. In your expertise, what could be causing this? Thank you.

The front brake rotors are warped causing the thumping or the antilock brakes are engaging when they should not be. If the problem is in need of repairs then contact a certified mechanic, such as one from YourMechanic, to inspect your car’s braking issue and make the necessary repairs for you.
