Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Wear safety gloves and goggles.

2. Remove Wheel

Use a lug wrench to loosen lug nuts slightly while the vehicle is on the ground.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Inspection
- Check the thickness of the brake pads; they should be at least 3mm thick.
- Look for uneven wear patterns.
Replacement
- Remove the caliper bolts using a socket wrench.
- Carefully slide the caliper off the rotor and suspend it using a bungee cord (do not let it hang from the brake line).
- Remove the old brake pads from the caliper bracket.
- Install new brake pads into the caliper bracket.
- Compress the caliper piston using a brake caliper tool to accommodate new pads.
- Reattach the caliper over the new pads and secure it with caliper bolts (torque to manufacturer specifications, typically around 25-35 ft-lbs).

4. Inspect and Replace Brake Rotors (if necessary)

If rotors show significant wear or scoring, remove them by unscrewing the rotor retaining screws.
Install new rotors by aligning them with the hub and securing with screws.
Ensure rotors are clean and free from grease or dust.

5. Reassemble and Bleed Brakes (if applicable)

Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque lug nuts to the specified value (typically around 80-100 ft-lbs).
If brake fluid was replaced, bleed the brake system to remove air bubbles.
