Here is how to complete this repair:
1. Have the right tools.
To change your brakes, you’ll need:
- a lug wrench to remove the tires
- a bottle jack or floor jack
- jack stands
- an Allen wrench for the caliper bolts (car dependent)
- a torque wrench
- a C-clamp to compress the caliper pistons
- a block of wood to place over the caliper boot during compression
- wire to support the caliper assembly during brake pad and rotor replacement
2. Before lifting your car with a jack, chock all wheels that will not be worked on.
Before you start, make sure your car is parked on flat ground with the parking/emergency brake engaged. Next, chock all of the wheels you aren’t working on. You can go out and purchase wheel chocks from your local auto parts store, but a wedge of wood or other sturdy material from the garage can also work. Once the wheels are chocked, lift the vehicle with a floor jack high enough to release a major portion of weight from the tire assembly.
3. Loosen the lug nuts with a tire iron, and support the axle with a jack stand.
Use your lug wrench to loosen the lug nuts. Once they’re loose, lift the vehicle until the tire is clear off the floor. At this point, it’s also a good idea to support the axle with a jack stand as an extra safety precaution.
4. Once you feel the car is not going to move, remove the tire, then loosen the caliper slide pins/bolts.
If the brake you’re changing is on the front of the car, it’s helpful to turn the steering wheel so the caliper is facing away from the car. This will give you easier access to the caliper bolts. Loosen the top and bottom bolts that are holding the caliper to the knuckle, making sure to not back them all the way out just yet.
5. Secure the caliper assembly, and then completely remove the bolts.
Before you completely back out the caliper bolts, be sure to support the caliper assembly with wire, rope, or something similar so the caliper doesn’t fall. If it does, you risk damaging the brake line. Once you completely back out the bolts and remove the caliper from the axle assembly, hang the caliper in the wheel well anywhere you can.
6. Pull the rotor toward you to release it from the axle assembly.
Now that the caliper is out of the way, you can remove the rotor. This is the first step that may be a challenge. If it won’t move, a torch might be required to heat the rotor, causing it to expand and break free from any rust or corrosion.To prevent this from happening again, you should use LOCTITE® LB 8070™ Heavy Duty Anti-Seize Stick on the rotor backing plate. The black anti-seize blended in well, so it may be hard to make out in the photo. You will want to work the material between all the studs and hub to alleviate rusting. This will make it much easier to remove the rotor next time around.
