Solution

1. Preparation

Gather tools and safety equipment.
Park the vehicle on a level surface and engage the parking brake.
Wear safety glasses and gloves.

2. Remove Wheel

Tools Required: Jack, jack stands, lug wrench
Loosen the lug nuts on the affected wheel slightly while the vehicle is still on the ground.
Use the 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

Tools Required: Torque wrench, brake cleaner, inspection mirror
Inspect the brake pads for even wear; replace any that are worn unevenly.
Check the brake caliper for proper operation; look for signs of sticking or fluid leaks.
Inspect the rotors for warping or uneven surfaces; resurface or replace if necessary.

4. Check Suspension and Alignment

Tools Required: Alignment tool (if available)
Inspect suspension components for wear, including bushings and ball joints.
Check alignment settings; adjust if misaligned.

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer’s specifications.
Test drive the vehicle to ensure proper braking function and monitor for any recurring symptoms.
