Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Gather safety gear including gloves and safety glasses.

2. Remove Wheel

Tools Required: Socket set, jack stands.
Loosen the lug nuts slightly before raising the vehicle.
Lift the vehicle with a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Remove the caliper:
- Tools Required: Socket set, torque wrench.
- Unbolt the caliper from the mounting bracket and carefully hang it using a wire (do not let it dangle on the brake line).
Remove old brake pads:
- Check the thickness; replace if below manufacturer specifications.
Install new brake pads:
- Apply brake grease on the backing of the pads to prevent noise.
- Ensure the pads are seated correctly in the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Check the rotors:
- If they are warped or have deep grooves, they need replacement.
Remove the rotor:
- Unscrew any retaining screws if present.
- Pull the rotor off the hub; if stuck, gently tap it with a hammer.
Install new rotor:
- Slide the new rotor onto the hub, ensuring it fits snugly.
- If applicable, secure it with the retaining screws.

5. Reassemble Brake Components

Reattach the caliper:
- Ensure it is aligned properly over the new pads and rotor.
- Torque the caliper bolts to manufacturer specifications.
Reinstall the wheel:
- Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle:
- Remove jack stands and carefully lower the vehicle to the ground.
Tighten lug nuts:
- Use a torque wrench to tighten to manufacturer specifications in a crisscross pattern.
