Tools and Materials Needed
- Jack and jack stands
- Lug wrench
- Socket set
- Brake cleaner
- Brake fluid
- New brake pads and rotors (if necessary)
Step 1: Park your car in a safe location
- Engage the parking brake.
- Turn off the engine and allow it to cool down.
Step 2: Loosen the lug nuts
- Locate the lug nuts holding the wheel in place.
- Use a lug wrench to loosen the lug nuts, but don't remove them completely.
- If you cannot remove the lug nuts using a standard lug wrench, you may need to use an impact wrench.
Step 3: Raise your car
- Place the floor jack under the front or rear end of your car, near the wheel you'll be working on.
- Use the jack to slowly lift your car until it is a few inches off the ground.
- Place a jack stand under the car, close to the wheel you are servicing, for safety. Lower your car carefully so the jack stands are supporting it.
Step 4: Remove the lug nuts and wheel
- Remove the lug nuts using a lug wrench.
- Remove the wheel and set it aside.
Step 5: Remove the brake caliper:
- Locate the brake caliper on the back of the wheel hub.
- There are two bolts holding the caliper in place. Remove these bolts using the correct size socket.
- If you cannot see the bolts due to rust, you may need to use a wire brush to clean the area around the bolts until they are visible.
- Carefully set aside the caliper and do not let it hang from the brake line.
Step 6: Remove the old brake pads
- Use a pry bar or screwdriver to pry the old brake pads out of the caliper.
- Try not to damage the caliper during this process.
Step 7: Clean the caliper:
- Use brake cleaner to clean the surface of the caliper where the brake pads sit. Make sure that all dirt, grease, and old brake pad material are removed.
Step 8: Install the new brake pads
- Slide the new brake pads into the caliper.
- Make sure that the pads are seated correctly and flush against the caliper piston.
Step 9: Reinstall the caliper:
- Place the caliper back on the wheel hub and secure it with the bolts. Tighten these bolts until they are snug but do not overtighten.
Step 10: Reinstall the wheel
- Place the wheel back on the wheel hub.
- Install and tighten the lug nuts until they are snug.
Step 11: Repeat steps 3-10 to replace the brake pads on the other wheel.
Step 12: Check brake fluid level
- Open the brake fluid reservoir and check the level of the brake fluid.
- If the level is low, add brake fluid until it is about 1/2 inch below the top of the reservoir.
- Do not overfill the brake fluid reservoir, as this can cause problems with the braking system.
Step 13: Test the brakes
- Once the new brake pads are installed, test the brakes before driving the car.
- Press the brake pedal a few times to make sure that the brakes work properly. The brake pedal should feel firm and responsive.
- If the brake pedal feels spongy or if the brakes do not work properly, you may need to have the braking system inspected and repaired by a qualified mechanic.
NOTE: If you are uncomfortable performing this task or do not have the necessary tools, it is recommended that you take your vehicle to a qualified mechanic to have the brakes changed.
