What happens if you put new brake pads on bad rotors?

If new brake pads are put onto a vehicle with damaged rotors, the pad will not properly contact the rotor surface which will reduce the vehicle’s stopping ability. Deep grooves that have developed in a worn rotor will act as a hole-puncher or shredder and damage the pad material as it is pressed against the rotor.

Can you still drive with worn brake pads?

As we have said, continuing to drive with worn brake pads is dangerous, and you should never let your pads get to the point where you can hear a harsh, metallic grinding noise. The grinding noise is the sound of metal on metal, and indicates brake pads which have been completely worn down.

Can you put new brake pads on worn rotors?

When properly bedded and used over time, a thin layer of brake pad material is transferred to the brake rotor surface, and this helps create optimal friction for stopping. When a set of pads is worn out and need to be replaced, it is perfectly ok to install a new set of pads on the old rotors.
