Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a flat surface, engage the parking brake, and secure the wheels with chocks.
Disconnect the negative battery terminal to ensure safety.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts slightly.
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

Remove the caliper bolts using a socket set.
Carefully slide the caliper off the rotor; support it with a bungee cord to avoid stress on the brake line.
Inspect brake pads for wear; replace if the thickness is below manufacturer's specifications.
If replacing, remove the old pads and install new pads, ensuring they are properly seated.

4. Clean and Lubricate Components

Clean the brake caliper bracket and rotor with brake cleaner.
Apply anti-squeal lubricant to the back of the new brake pads and on the caliper contact points.
Inspect and clean or replace any shims or clips as necessary.

5. Reassemble Components

Reinstall the caliper over the new pads and secure it with the caliper bolts, tightening to the manufacturer's torque specifications.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the specified value in a crisscross pattern.

6. Final Checks

Reconnect the negative battery terminal.
Test the brake pedal for firmness before driving.
