Why do my brakes grind after new pads?

New brake pads are a bit stiff and need to be broken in. The process of breaking in new brake pads is referred to as bedding in. When your pads are being bedded in, you may hear some squealing, screeching or grinding. But this noise should lessen as you drive your car and allow the pads to become worn in.

Should brakes grind after being replaced?

Grinding, Not Squeaking It’s not likely that you’ll hear grinding after getting your brake pads replaced, since a metal-on-metal sound typically means you’ve worn out your brake pads to the point that their wear indicators, or in a worst-case scenario, metal backing plates are exposed and grinding against the rotors.

How long does it take for new brakes to break in?

“Bedding-in new pads and rotors should be done carefully and slowly… Most brake pad compounds will take up to 300-400 miles to fully develop an even transfer film on the rotors.” Failure to follow these procedures may result in brake judder, excessive noise, or other difficulties in bedding-in the new brake pads.

Will brake cleaner stop grinding?

It sounds as if the piston to your caliper is sticking, especially given that the noise goes away when you apply your brakes. Some fine emery cloth and brake cleaner (similar to carb cleaner but leaves no residue) can fix that.

What should new brake pads feel like?

Under optimum operating conditions, your brake pedal should feel firm throughout its travel. The harder you push it, the firmer it should feel. When you mash the brakes quickly, like we’ve all done from time to time to avoid rear-ending someone, your brake pedal will be at its firmest.
