Solution

1. Preparation

Gather tools and parts.
Ensure vehicle is parked on a level surface and engage the parking brake.
Safety warning: Disconnect the battery before working on electrical components.

2. Remove Wheel

Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts using a socket set and take off the wheel.

3. Inspect and Replace Brake Pads

Inspection:
- Check the brake pads for minimum thickness (should be at least 3mm).
- If worn, proceed with replacement.
Replacement:
1. Remove the caliper bolts using a socket wrench.
2. Carefully slide the caliper off the rotor.
3. Remove old brake pads from the caliper bracket.
4. Install new brake pads in the bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Inspection:
- Check rotors for scoring or excessive wear.
Replacement:
1. If rotors are damaged, remove them by unscrewing the retaining screws (if applicable) and sliding them off the hub.
2. Install new rotors and secure them properly.

5. Reassemble Components

Reinstall the brake caliper over the new pads and rotor.
Tighten caliper bolts to manufacturer specifications (usually around 20-25 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.

6. Final Checks

Lower the vehicle and torque the lug nuts to the manufacturer’s specifications (typically 80-100 ft-lbs).
Reconnect the battery if it was disconnected.
