Solution

1. Preparation

Tools Required: Socket set, torque wrench, jack stands, wheel chocks, dial indicator.
Safely park the vehicle on a flat surface and engage the parking brake.
Place wheel chocks behind the rear wheels.
Disconnect the battery before working on the brake system to avoid accidental activation.

2. Remove Wheel

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

3. Inspect Brake Components

Brake Pads:
- Remove the brake caliper by loosening the caliper bolts.
- Inspect the brake pads for uneven wear or damage.
- Replace pads if worn beyond the manufacturer's specifications.
Brake Rotors:
- Measure the rotor thickness with a micrometer to ensure they are within specifications.
- Use a dial indicator to check for warpage. Replace rotors if they exceed allowable limits.

4. Reassemble Brake Components

If components were replaced, install new brake pads and rotors.
Reattach the brake caliper and torque the caliper bolts to manufacturer specifications (typically around 23-30 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.

5. Lower Vehicle

Carefully lower the vehicle from the jack stands using the jack.
Tighten the lug nuts to the manufacturer's torque specification (typically 80-100 ft-lbs).

6. Brake Fluid Check

Check the brake fluid level; top off with the appropriate brake fluid type (usually DOT 4).
Bleed the brakes if necessary to remove any air from the brake lines.
