How to Break In New Brake Pads | O'Reilly Auto Parts

Skip to content

Breaking in new brake pads once you’ve completed a brake job is an important final step in the operation and safety of your pads and rotors. This “bedding” process will allow your new brakes to perform more smoothly and quietly by transferring an even layer of friction material from the pads to the rotors, which can help prevent vibration and extend the life of the new components. If you’ve completed your brake job and it’s time to break in the new pads and rotors, the following procedure will work, regardless of the vehicle.

Step 1: Pump the Brake Pedal

Once the entire brake job is done, pump your brake pedal a few times until the pressure has returned. If the pedal feels spongy, you may have air in your brake lines. You’ll need to bleed your brakes if that’s the case. If you need to perform this procedure, learn more about how to bleed your brakes with our step-by-step instructions.

Step 2: Go For a Drive

Once the pedal feels like it should, take your vehicle out for a drive, slowing it down thirty or so times from thirty miles per hour with moderate brake pressure, allowing the brakes to cool for about thirty seconds in between each slowdown. Try to avoid aggressive stops during this process.

Step 3: Tips and Diagnosis

If your brakes have a slightly burnt or rubbery smell after you’ve done this, that’s okay. If you notice the odor persisting beyond five hundred miles or so, or if you have excessive dust on a wheel, you may have a stuck caliper.

As tempting as it may be to jump in your car and start driving like normal after a brake job, bedding in your new brake pads and rotors is an essential step in the process. Not only does the break-in ensure smooth, comfortable braking performance, it helps your new components function safely for a longer period of time.
