Solution

1. Preparation

Gather tools: socket set, torque wrench, brake cleaner, micrometer, and safety glasses.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working on the braking system.

2. Remove Wheel

Loosen the lug nuts on the affected wheel using a socket wrench.
Lift the vehicle using a jack and secure it with jack stands.
Remove the lug nuts and take off the wheel.

3. Inspect Brake Components

Rotors:
- Measure rotor thickness with a micrometer.
- Check for warping using a dial indicator.
- If warped or below minimum thickness, replace rotors.
Pads:
- Inspect brake pads for wear; replace if less than 3mm thick.
Calipers:
- Check caliper operation; ensure they move freely and do not stick.

4. Replace Components as Necessary

If rotors are warped:
- Remove caliper bracket bolts and remove the caliper.
- Detach the rotor from the hub.
- Install new rotor and torque the bolts to manufacturer specifications.
If brake pads are worn:
- Remove the old pads from the caliper.
- Install new pads ensuring proper orientation and alignment.

5. Reassemble and Test

Reattach caliper and secure with bolts, torquing to specified values.
Reinstall the wheel and lug nuts, lowering the vehicle back to the ground.
Torque lug nuts to manufacturer specifications.
Reconnect the battery.
