Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Disconnect the negative terminal of the battery to prevent electrical issues.

2. Remove Wheel

Using a socket set, loosen the lug nuts of the wheel where the brakes are squeaking.
Lift the vehicle using a jack and secure it with jack stands.
Completely remove the lug nuts and take off the wheel to access the brake components.

3. Inspect Brake Components

Brake Pads: Remove the brake caliper by unscrewing the caliper bolts. Inspect the brake pads for thickness. Replace if they are worn down to less than 3mm.
Brake Rotors: Check for any scoring or warping. If damaged, replace the rotors with OEM-spec replacements. Ensure to measure the rotor thickness before replacement.
Calipers: Inspect calipers for any signs of corrosion or sticking. If they are not functioning properly, consider rebuilding or replacing them.

4. Clean and Lubricate

Clean the brake pads, rotors, and calipers using brake cleaner to remove dust and debris.
Apply a thin layer of anti-squeal grease to the back of the brake pads (do not apply to the friction surface).
Ensure that the caliper slides are properly lubricated to allow for smooth operation.

5. Reassemble and Test

Reattach the brake caliper and torque the caliper bolts to the manufacturer's specifications (typically between 25-35 ft-lbs).
Reinstall the wheel and tighten the lug nuts in a crisscross pattern to the specified torque (usually around 100-110 ft-lbs).
Reconnect the battery and lower the vehicle.
