Solution

1. Preparation

Ensure the vehicle is parked on a level surface.
Engage the parking brake and wear safety goggles.
Gather tools and parts.

2. Remove Wheel

Loosen lug nuts slightly while the vehicle is on the ground.
Raise the vehicle using a jack and secure it with jack stands.
Fully remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Inspect:
- Check the thickness of the brake pads; if less than 3mm, replace.
Remove:
- Use a socket wrench to remove the caliper bolts.
- Carefully slide off the caliper and suspend it using a bungee cord or rope to prevent stress on the brake line.
Replace:
- Remove old brake pads from the caliper bracket.
- Install new brake pads, ensuring they are properly aligned.
- Apply brake grease on the back of the pads to prevent noise.

4. Inspect and Replace Brake Rotors (if necessary)

Remove:
- If rotors are damaged, unbolt them from the hub using the appropriate socket.
Replace:
- Clean the new rotors with brake cleaner to remove any protective coating.
- Install new rotors, tightening bolts to manufacturer’s torque specifications (usually around 80-100 ft-lbs).

5. Reassemble and Bleed Brakes

Reattach the caliper over the new pads and torque the caliper bolts to the specified value (typically around 25-30 ft-lbs).
Repeat for the other side if necessary.
Bleed the brake system to remove any air:
- Start at the furthest wheel from the master cylinder, using a brake bleeder tool.
- Have an assistant pump the brake pedal while you open and close the bleeder valve.

6. Reinstall Wheel

Place the wheel back on, hand-tightening the lug nuts.
Lower the vehicle and torque the lug nuts to the specified value (usually around 80-90 ft-lbs).
