Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface, and engage the parking brake.
Wear safety glasses and gloves.

2. Remove Wheel Assembly

Loosen lug nuts using a socket set.
Raise the vehicle with a jack and secure it with jack stands.
Remove the wheel to access the brake components.

3. Inspect and Replace Brake Components

Brake Pads:
- Remove the caliper bolts using a socket.
- Lift the caliper away from the rotor; do not let it hang by the brake line.
- Inspect pads for uneven wear; replace if necessary.
- Install new brake pads, ensuring they sit evenly in the caliper.
Brake Rotors:
- Check rotor surface for scoring or warping.
- If uneven or damaged, remove the rotor by unscrewing the retaining screws and sliding it off.
- Install new rotors, ensuring they are torqued to the manufacturer’s specifications (typically around 90-100 ft-lbs).

4. Reassemble Brake Components

Reattach the caliper over the new pads and rotor.
Secure caliper bolts to the appropriate torque specification.
Reinstall the wheel and hand-tighten the lug nuts.

5. Final Checks

Lower the vehicle and torque the lug nuts to manufacturer specifications.
Check brake fluid level and top off if necessary.
Press the brake pedal several times to ensure proper seating of brake pads.
