How to Change Rotors

Brake Rotors

They may be made of durable cast iron, but your brake rotors aren’t designed to last forever. Occasionally, you’ll need to replace them, and if you’ve ever wondered how to change rotors, just follow the easy steps outlined below.

At Ira Toyota of Manchester, we’re happy to provide Amherst, Manchester, and Derry drivers with all the information they need for DIY brake repair. If you have any questions, just reach out to us!

Step 1: Raise Your Vehicle

Car Jack

You’ll need to get your car off the ground to change the rotors. Start by loosening the lug nuts with a tire iron. (You don’t need to fully remove them just yet.) Then, use a car jack to raise your car and place some jack stands underneath to keep it secure.

At this point, you can remove the loose lug nuts and wheels by hand. The wheels should easily pull off the wheel hub, so you can reach the brake mechanisms more easily.

Step 2: Remove Caliper Assembly

Now, it’s time to remove the caliper assembly, the clamp-like device that pushes the brake pads against the rotors to stop the car. With a socket wrench, remove the bolts at the back and slide the assembly off the rotor.

The caliper assembly will still be connected to your car via the brake line. Don’t leave it hanging from the brake line, as a snapped brake line can be difficult and expensive to replace. With a piece of wire, you can hang it in the wheel well. Be sure not to let it fall.

Step 3: Change Rotors

With the caliper assembly out of the way, you should be able to remove the rotor. It might be connected by a screw or clip that needs to be removed, but otherwise, you can just slide the rotor off the wheel stud. Keep in mind, the rotor may be hard to remove if it has rusted into place.

Clean the wheel stud or replace it, if you notice any corrosion. Then, slide your new rotors into place and tighten any screws or clips that you removed earlier.

Step 4: Replace Caliper Assembly

Now, reinstall the caliper assembly and bolt it back into place. If you also changed your brake pads during this procedure, you may notice the assembly doesn’t fit over the new, thicker pads. To adjust it, use a C clamp to push the circular piston back into the caliper, and it should fit easily.

Step 5: Lower the Car

At this point, you’re basically finished. All you need to do is re-mount the wheels, tightening the lug nuts as best you can be hand. Next, use the car jack to lower your vehicle to the ground and fasten all lug nuts fully with the tire iron. Congratulations: You know how to change rotors!
