Solution

1. Preparation

Gather required tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Wear safety gloves and goggles.

2. Remove Wheel

Loosen the lug nuts using a lug wrench while the vehicle is on the ground.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts and take off the wheel.

3. Inspect Brake Pads

Locate the brake caliper and inspect the brake pads for thickness.
- Minimum thickness should not be less than 3mm.
- If the pads show signs of uneven wear or are below the minimum thickness, they need replacement.
Look for any cracks or damage on the brake pads.

4. Check Brake Rotors

Inspect the brake rotors for grooves, scoring, or rust.
Measure the rotor thickness using a micrometer; replace if below manufacturer's specifications.

5. Reassemble

Reinstall the wheel, hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer’s specifications.

6. Test

Perform a test drive to ensure brakes are functioning properly after inspection.

Tools Required:

Lug wrench
Jack and jack stands
Brake pad thickness gauge or caliper
Micrometer (for rotor thickness)
Multimeter (if applicable)

Parts Required:

New brake pads (if worn)
New rotors (if necessary)

Estimated Repair Time: 1-2 hours

Safety Warnings:

Always use jack stands when working under a vehicle.
Ensure the vehicle is securely lifted before removing any wheels.
