Tools Needed:
- Lug wrench
- Jack and jack stands (or ramps)
- Socket wrench with appropriate sockets
- C-clamp or brake caliper tool
- Flat-head screwdriver
- Caliper grease
- New brake pads
Instructions:
1. Loosen the Lug Nuts:
- Use the lug wrench to loosen (but do not fully remove) the lug nuts on the wheel where you'll be replacing the brake pads.
2. Raise the Vehicle:
- Place the jack under a solid part of the vehicle's frame and raise it until the tire is off the ground.
- Secure the vehicle using jack stands or ramps to ensure it remains stable.
3. Remove the Wheel:
- Remove the lug nuts completely and take off the wheel.
4. Locate the Brake Caliper:
- You'll see the brake caliper on the back of the wheel hub. It's typically held in place by two bolts.
5. Remove the Brake Caliper:
- Use the socket wrench to remove the bolts that hold the caliper in place.
- Once the bolts are removed, carefully lift the caliper and set it aside, being mindful of the brake line attached to it.
6. Remove the Old Brake Pads:
- You'll see the old brake pads inside the caliper. They're usually held in place by clips or bolts.
- Use the flat head screwdriver to release any clips or remove any bolts holding the pads in place.
- Carefully slide out the old brake pads.
7. Inspect Other Components:
- While the brake pads are out, inspect the brake rotor for wear or damage. If the rotor is worn or warped, it may need to be replaced as well. Also, inspect the caliper for any issues.
8. Install New Brake Pads:
- Insert the new brake pads into the caliper, ensuring they're properly seated and aligned.
- Secure the new brake pads with the clips or bolts you removed earlier.
9. Reinstall the Brake Caliper:
- Carefully place the caliper back over the brake pads and align it with the mounting bolts.
- Reinsert and tighten the bolts that secure the caliper.
10. Release the Caliper Piston:
- If the brake caliper has a piston, you may need to retract it to make room for the new brake pads. Use a C-clamp or brake caliper tool to push the piston back into the caliper.
11. Reinstall the Wheel:
- Put the wheel back on and secure the lug nuts. Do not tighten them fully yet.
12. Test the Brakes:
- Slowly lower the vehicle until it's just touching the ground, but not supporting its full weight.
- Press the brake pedal firmly and make sure the brakes are functioning properly.
13. Tighten the Lug Nuts:
- Once satisfied that the brakes are working correctly, lower the vehicle completely and tighten the lug nuts securely using the lug wrench.
14. Test Drive:
- Take your vehicle for a short test drive and ensure that the brakes feel normal and responsive.
Note:
If you're replacing brake pads on the rear wheels of a 2004 Ford Ranger, the procedure is similar, but the parking brake mechanism may be affected. Refer to your vehicle's specific repair manual for instructions on disengaging and re-engaging the parking brake during the brake pad replacement.
