Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Wear safety gloves and goggles.

2. Wheel Removal

Tools Required: Jack, jack stands, lug wrench.
Loosen lug nuts with the lug wrench before lifting the vehicle.
Use the jack to lift the vehicle and place jack stands for safety.
Remove the lug nuts completely and take off the wheel.

3. Brake Pad Inspection and Replacement

Remove the brake caliper by loosening the caliper mounting bolts using a socket set.
Carefully slide the caliper off the rotor and suspend it using a bungee cord or wire to avoid stress on the brake line.
Inspect the brake pads for thickness; if they are less than 3mm, replace them.
Sub-steps:
- Remove the old brake pads.
- Clean the caliper bracket and apply brake grease on contact points.
- Install new brake pads in the caliper bracket.

4. Rotor Inspection and Replacement

Check the rotor surface for any grooves or wear; if damaged beyond repair, replace it.
If replacement is necessary, remove the rotor by loosening the retaining screws if applicable.
Install the new rotor and ensure it is properly seated.

5. Reassembly

Reinstall the brake caliper over the new brake pads and rotor.
Torque the caliper mounting bolts to the manufacturer’s specifications (usually around 25-35 lb-ft).
Reinstall the wheel and hand-tighten the lug nuts initially.
Lower the vehicle and then torque the lug nuts to the manufacturer's specifications (typically around 76-85 lb-ft).
