Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, torque wrench, socket set, brake cleaner, and safety glasses.
Ensure the vehicle is on a flat surface and engage the parking brake.

2. Elevate the Vehicle

Use a jack to lift the front or rear of the vehicle as needed.
Secure with jack stands to ensure safety while working underneath.

3. Remove Wheel

Use a lug wrench to loosen and remove the lug nuts.
Take off the wheel to access the brake components.

4. Inspect Brake Components

Brake Pads: Remove the caliper bolts and slide the caliper off to inspect the pads. Replace if worn down below 3mm.
Rotors: Check the rotor surface for grooves or warping. Resurface or replace if necessary.
Calipers: Ensure calipers are moving freely. Clean and lubricate the caliper slides if they are sticking.

5. Reassemble and Torque

Reinstall the brake caliper over the new or inspected brake pads.
Replace the wheel and hand-tighten lug nuts.
Lower the vehicle and use a torque wrench to tighten lug nuts to the manufacturer’s specifications (typically 80-100 lb-ft).
