Easy Steps to Replace Brake Pads and Rotors
Your brake pads and rotors help your vehicle make safe stops, so it’s important to replace them when necessary. AutoZone recommends inspecting or having your brake pads inspected when rotating or changing your tires.
If you’re experiencing an issue like squealing, squeaking or grinding, pulsation from the pedal, steering wheel shimmy (or shaking), this could be an indication of worn or failing pads or rotors. AutoZone recommends replacing pads and rotors together for a complete brake job.
Check out the video above or keep scrolling for general steps on how to replace brake pads and rotors in the most vehicles.

General Steps for replacing brake pads and rotors
Check the brake fluid level
Open the hood and check the brake fluid reservoir. If it’s full, some fluid needs to be removed. This will help avoid spillage due to overflow when compressing the brake caliper piston.
Raise the vehicle and remove the wheel
Loosen the lug nuts with a breaker bar and socket while the wheel is on the ground and stationary. Raise the vehicle with a hydraulic jack from a secure point. Place a jack stand or stands under the appropriate points and safely lower the vehicle onto the jack stands. Remove the lug nuts and the wheel.
Remove the bolts and the caliper
You should be able to reach the caliper bolts pretty easily. Turning the wheel left or right will provide easier access. Once the caliper is removed, suspend it with a bungee cord. Note: Removing the caliper may require different steps on your vehicle.
Remove the old pads and rotor
Inspect the old pads for uneven wear patterns. Uneven wear is an indicator of the pad or pads ‘sticking’ due to lack of lubricant, worn pad or caliper hardware, or a sticking caliper piston. The brake pad box will have a guide to reference when inspecting for uneven wear, or you can reference this guide.
Once the pads are off, remove the rotor. On many vehicles, you'll need to remove the caliper mounting bracket in order to remove the rotor. The brake caliper bolts to the brake caliper mounting bracket which bolts to the spindle assembly. To remove the brake rotor, first remove the brake caliper and then remove the brake caliper bracket. This will allow access to the rotor.
Clean the rotor mounting surface
The hub surface needs to be cleaned with a wire brush to remove rust and debris. This will ensure the new rotor sits flush on the hub and eliminates the possibility of pedal pulsation. Rust as thin as a sheet of paper can translate to pedal pulsation.
Clean the new rotor
Grab some AutoZone Brake Cleaner. Duralast Gold Rotors come with a rust fighting protection coating, so you can skip this step if you've got those.
Install the new rotor
Look at you. You’re doing great.
Install brake hardware
Replace the brake hardware with new hardware. When worn, old brake hardware creates vibrations that is heard in the form of brake noise and low stopping speeds. These clips should be replaced with each brake job. Make sure to apply brake lubricant at the slider contact points before installing the hardware.
Get brake pads ready to install
Note the wear-sensor position orientation to install the pads correctly. Different pads have varying wear-sensor placement. Some pad sets have wear sensors on just the inner pads, some on all four pads, and some do not have wear sensors.

Inspect brake caliper and piston, then compress
Look at the brake caliper and piston and inspect it for any brake fluid seepage. If the caliper and piston are clean, use the front/rear disc brake pad spreader set to safely seat the caliper piston. You can borrow the spreader set for free from any AutoZone through Loan-A-Tool.* On some rear disc brakes, the caliper pistons screw in, and require the disc brake pad spreader set to be seated properly.
Install the caliper
Take the caliper off the bungee cord and put it back on. VERY IMPORTANT – DO NOT OVERTIGHTEN the caliper bolts. This can lead to much bigger problems. Start tightening the bolts with a socket, then use a torque wrench to tighten the bolts correctly. You can borrow a torque wrench for free at any AutoZone through Loan-A-Tool. Consult a repair guide for proper torque specs.
Check brake fluid reservoir
Top-off to the max fill line if needed. Be sure the brake fluid reservoir cap is installed before going to the next step. This will avoid spillage.
Pump the brakes
This will make sure brake fluid is flowing properly and the system is working. Sit in the vehicle and slowly pump the brake pedal until it feels firm. CAUTION Do NOT press the brake pedal all the way to the floor. This may cause internal damage to the brake master cylinder assembly.
Check the brake fluid reservoir again
Top-off again if necessary. Always re-install the cap after topping off to avoid spillage.
Install the wheel and lower the vehicle
Install the wheel and tighten the lug nuts while the vehicle is raised. Raise the vehicle with a jack, remove the jack stands, lower the vehicle until the wheel is just touching, and tighten the lug nuts with a torque wrench. Consult your owner’s manual for the proper torque for your vehicle.
Repeat on the remaining wheels
Make sure the brake pedal is firm before driving.
Go for an easy drive
Go for a safe, easy drive to break in the new brakes. On a safe road, accelerate to around 50mph. Apply the brakes, not too hard, and slowly bring the vehicle’s speed down to 30mph. Continue to drive at this speed for 2 to 3 minutes to allow the brakes to cool. Repeat this process four to five times until the new brakes are ready for daily use.
Note: These steps provide a general outline for replacing brake pads and rotors on the front disc brakes of most vehicles. Some steps may vary by year, make and model. Reference a repair guide or one of our vehicle specific videos for more specific information. AutoZone has more guides for brake replacement that you can reference here.

Information is accurate and true to the best of AutoZone’s knowledge, however, there may be omissions, errors or mistakes.
Be sure to consult your owner’s manual, a repair guide, an AutoZoner, or a licensed, professional mechanic for vehicle-specific repair information. Refer to the service manual for specific diagnostic, repair and tool information for your particular vehicle. Always chock your wheels prior to lifting a vehicle. Always disconnect the negative battery cable before servicing an electrical application on the vehicle to protect its electrical circuits in the event that a wire is accidentally pierced or grounded. Use caution when working with automotive batteries. Sulfuric acid is caustic and can burn clothing and skin or cause blindness. Always wear gloves and safety glasses and other personal protection equipment, and work in a well-ventilated area. Should electrolyte get on your body or clothing, neutralize it immediately with a solution of baking soda and water. Do not wear ties or loose clothing when working on your vehicle.
