Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, torque wrench, brake cleaner, and safety goggles.
Park the vehicle on a flat surface and engage the parking brake.
Wear safety goggles and gloves for protection.

2. Remove Wheel

Loosen the lug nuts with a lug wrench.
Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect Brake Components

Brake Pads:
- Remove the caliper bolts using a socket set.
- Lift the caliper away from the rotor and support it using a bungee cord (do not let it hang by the brake line).
- Inspect the brake pads for thickness; they should be at least 3mm thick.
Brake Rotors:
- Check the rotor surface for grooves or warping.
- Measure rotor thickness; if below specifications, replacement is necessary.

4. Clean and Lubricate

Use brake cleaner to clean the rotors and pads, removing dust and debris.
Apply anti-squeal lubricant to the back of the brake pads and any contact points on the caliper or bracket.

5. Reassemble Components

Reattach the caliper to the rotor and secure it with caliper bolts; torque to manufacturer specifications.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and fully tighten the lug nuts in a star pattern to ensure even torque.
