Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and securely lifted with jack stands.
Wear safety glasses and gloves.

2. Remove Wheel

Tools Required: Lug wrench, socket set.
Loosen the lug nuts slightly while the vehicle is on the ground.
Lift 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 (if needed)

Tools Required: Socket set, brake caliper tool, torque wrench.
Remove the brake caliper by unscrewing the caliper bolts.
Carefully slide the caliper off the brake pads and hang it using a wire to avoid strain on the brake line.
Remove the old brake pads from the caliper bracket.
If the pads are worn below the manufacturer’s specifications, replace them with new pads.
Apply anti-squeal grease to the back of the new pads (if recommended) to reduce noise.

4. Inspect and Replace Brake Rotors (if needed)

Check the rotors for damage or excessive wear.
If the rotors are scored or warped, remove them by unscrewing the retaining screws (if applicable) and sliding them off the hub.
Install new rotors ensuring they are clean and free of debris.

5. Reassemble Components

Reinstall the brake caliper over the new pads and rotors.
Tighten the caliper bolts to the manufacturer's specified torque.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and fully tighten the lug nuts to the specified torque.
