Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface, and engage the parking brake.
Disconnect the battery if working on electrical components.

2. Remove Wheel

Loosen the lug nuts using a socket wrench.
Lift the vehicle using a jack and secure with jack stands.
Remove the lug nuts and take off the wheel.

3. Inspect Braking Components

Remove the brake caliper by unscrewing the caliper bolts using a socket wrench.
Carefully hang the caliper to avoid stress on the brake line.
Check the brake pads for wear; if they are less than 3 mm thick, replace them.
Inspect the brake rotor for any scoring or warping. If damaged, replace the rotor.

4. Clean and Lubricate

Clean the brake components, especially the caliper bracket and the back of the brake pads, using brake cleaner.
Apply anti-squeal lubricant to the back of the brake pads to minimize noise.
Ensure the anti-squeal shims are intact and properly installed.

5. Reassemble Components

Reattach the brake caliper and secure it with the bolts, tightening them to the manufacturer's torque specifications.
Place the wheel back on and hand-tighten the lug nuts.
Lower the vehicle and tighten the lug nuts to the correct torque value.

6. Test Brake Functionality

Reconnect the battery (if disconnected).
Start the vehicle and pump the brakes a few times to seat the pads.
Test the brakes at low speed to ensure proper function and listen for noise.
