Solution

1. Preparation

Tools Required: Jack and jack stands, wheel chocks, lug wrench, torque wrench, brake cleaner, and safety glasses.
Safety Warnings: Ensure the vehicle is on a flat surface and secure with wheel chocks. Wear safety glasses for eye protection.

2. Raise the Vehicle

Use the jack to lift the vehicle and secure it on jack stands.
Remove the rear or front wheels using the lug wrench.

3. Inspect Brake Components

Brake Pads: Remove the brake caliper bolts and slide the caliper off the rotor. Inspect the brake pads for wear; replace if they are worn below the manufacturer's specifications (usually 3mm).
Brake Rotors: Check the rotor surface for grooves, rust, or warping. Measure rotor thickness with a micrometer; replace if below the minimum thickness specified by the manufacturer.

4. Clean and Lubricate

Clean the brake components with brake cleaner to remove dust and debris.
Apply brake grease to the caliper slide pins and the back of the brake pads to reduce noise.

5. Reassemble Components

Reinstall the brake caliper and torque the bolts to the manufacturer’s specifications (usually around 25-35 ft-lbs).
Reinstall the wheels and torque the lug nuts in a star pattern to the specified torque.

6. Test Brakes

Lower the vehicle and perform a brake test at low speed to check for noise. Ensure the brakes engage smoothly without unusual sounds.
