Tools and Materials Needed:
- Jack and jack stands
- Lug wrench
- Socket set
- Flat-head screwdriver
- Wire brush or sandpaper
- Brake parts cleaner (spray)
- New brake pads
- C-clamp or brake caliper spreader
- Rags
- Safety glasses
Procedure:
1. Park the car on a level surface, turn off the engine, and engage the parking brake.
2. Loosen the lug nuts on the wheels where you will be replacing the brake pads. Do not remove them completely at this point.
3. Raise the car using the jack and secure it with the jack stands. Ensure the car is stable and secure before proceeding.
4. Remove the lug nuts and take off the wheels.
5. Locate the brake caliper. It is usually attached to the steering knuckle and holds the brake pads in place.
6. Remove the two bolts holding the caliper in place using a socket wrench. Be careful not to lose any parts or springs that might fall out during this step.
7. Gently swing the caliper upwards to expose the brake pads. Do not let the caliper hang by the brake hose.
8. Inspect the brake pads. If they are worn down to less than 1/4 inch (6 mm) or if the friction material is damaged, cracked, or glazed, they need to be replaced.
9. Clean the brake caliper and rotor using a wire brush or sandpaper to remove any dirt, rust, or debris.
10. Apply brake cleaner to the caliper and rotor to remove any remaining contaminants.
11. Use a C-clamp or brake caliper spreader to compress the caliper piston back into the caliper. This creates space for the new, thicker brake pads.
12. Install the new brake pads into the caliper. Make sure they are seated correctly.
13. Reattach the caliper to the steering knuckle using the bolts you removed earlier. Tighten them securely.
14. Replace the wheel, lug nuts, and lower the car back down.
15. Repeat the process for the other wheel if necessary.
16. Test the brakes by applying gentle pressure to the brake pedal. Ensure the brakes feel firm and engage smoothly.
Note: It is important to follow proper safety precautions when working on brakes. Always wear safety glasses and use the appropriate tools. If you are not comfortable performing this task or if your vehicle has specific requirements, it is best to consult a qualified mechanic or refer to the vehicle's repair manual.
