Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Use jack stands to secure the vehicle after lifting it.

2. Remove Wheel

Sub-steps:
- Loosen lug nuts slightly while the vehicle is on the ground.
- Lift the vehicle using a jack and secure with jack stands.
- Fully remove the lug nuts and take off the wheel.
Tools Required: Jack, jack stands, lug wrench.

3. Inspect and Replace Brake Components

Sub-steps:
- Remove the caliper by undoing the caliper bolts; support it with a bungee cord to avoid stress on the brake line.
- Check the brake pads for wear; if less than 3mm thick, replace them.
- If the pads are worn, remove them and clean the caliper bracket.
- Inspect the rotor; if it’s scored or below the minimum thickness, replace it. If it’s in good condition, consider resurfacing if necessary.
- Install new brake pads and reattach the caliper.
Tools Required: Socket set, torque wrench, brake cleaner.

4. Reassemble and Test

Sub-steps:
- Reinstall the wheel and hand-tighten the lug nuts.
- Lower the vehicle and then torque the lug nuts to the manufacturer’s specifications.
- Pump the brake pedal to seat the new pads.
Tools Required: Torque wrench.
