Do new brakes have a break in period?
Many brake experts recommend breaking in new brake pads with a 30-30-30 procedure: 30 gradual stops from 30 mph with 30 seconds in between each stop for the brakes to cool. This procedure will prevent the pads from getting too hot until the resins have fully cured.
Is it normal for new brake pads and rotors to make noise?
What To Do If Your Car Brakes Are Making Grinding Noise After New Pads And Rotors Are Installed. You may notice a grinding noise after you get new brake pads and rotors.

What happens if you don’t bed in brakes?
If the pads and rotors have not been bed-in correctly, the mechanism of Abrasive and Adherent friction will not work well and use of the brake system, especially at high temperatures, will result in random and uneven deposits of brake pad material on the rotor surface.
What happens if you don’t break in brakes?
Breaking in new brakes is also known as bedding-in the brake pads and rotors. If you don’t properly bed in brakes, you may experience problems with the braking system down the road, such as warped discs, uneven brake pad wear, or noise brakes every time you tap on the brake pedal.
