Solution

1. Preparation

Gather all tools and parts before starting.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Wear safety gloves and goggles.

2. Remove Wheel

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

3. Inspect and Replace Brake Pads

Inspect: Check the thickness of the brake pads. If they are below the manufacturer's recommended thickness (typically 3mm), they need replacement.
Replace:
- Remove the caliper bolts using a socket set.
- Carefully slide the caliper off the brake rotor and support it without stressing the brake line.
- Remove the old brake pads from the caliper bracket.
- Install new brake pads in the caliper bracket, ensuring they are seated correctly.

4. Inspect and Replace Brake Rotors (if necessary)

If rotors are scored or below the minimum thickness (usually stamped on the rotor), replace them.
Remove the caliper bracket by unscrewing the bolts.
Slide the rotor off the hub. If it's stuck, tap gently with a rubber mallet.
Install the new rotor, ensuring it is seated properly on the hub.

5. Reassemble and Test

Reattach the caliper bracket and bolt it to the specified torque (usually around 25-35 ft-lbs).
Slide the caliper back over the new brake pads and secure it with the caliper bolts.
Replace the wheel and hand-tighten the lug nuts before lowering the vehicle.
Lower the vehicle and torque the lug nuts to the manufacturer’s specifications (typically 80-100 ft-lbs).
