Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and set the parking brake.
Use wheel chocks to prevent movement.

2. Remove Wheel

Sub-steps:
1. Loosen the lug nuts slightly while the vehicle is on the ground.
2. Raise the vehicle using a jack and secure it with jack stands.
3. Remove the lug nuts completely and take off the wheel.
Tools Required: Jack, jack stands, lug wrench.

3. Inspect Brakes

Sub-steps:
1. Visually inspect brake pads for uneven wear; replace if less than 3mm thick.
2. Check brake rotors for warping or excessive wear; replace if necessary.
3. If rotors are warped, measure run-out with a gauge; if out of spec, replace or resurface.
Tools Required: Torque wrench, caliper gauge.

4. Reassemble Components

Sub-steps:
1. Reinstall the brake caliper and secure it according to manufacturer specifications.
2. Reattach the wheel and hand-tighten lug nuts.
3. Lower the vehicle and fully tighten the lug nuts in a star pattern to the specified torque.
Torque Specification: Refer to the vehicle’s service manual for specific torque values.

5. Test Drive

After reassembly, perform a test drive to ensure the issue is resolved and brakes function properly.
