Solution

1. Preparation

Gather tools and materials: socket set, torque wrench, brake cleaner, dial indicator (for rotor inspection), and safety glasses.
Ensure the vehicle is parked on a level surface with the parking brake engaged.
Disconnect the battery for safety.

2. Remove Wheel

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

3. Inspect Brake Components

Brake Pads: Remove the caliper by unscrewing the caliper bolts. Inspect brake pads for thickness and wear. Replace if worn below specification (usually 3mm).
Brake Rotors: Use a dial indicator to check for warping. A variation greater than 0.002 inches indicates replacement. If uneven, replace the rotors.
Caliper: Ensure that the caliper slides freely. Lubricate the caliper pins if necessary.

4. Replace Components

If brake pads or rotors are worn, replace them:
- Brake Pads: Remove old pads and install new ones, ensuring they seat properly.
- Brake Rotors: Remove the old rotor and install a new one, ensuring proper alignment and securing with the specified torque (usually around 80-100 ft-lbs).

5. Reassemble and Test

Reattach the caliper and torque the bolts to the manufacturer's specifications (check the service manual for exact torque values).
Reinstall the wheel and torque the lug nuts in a crisscross pattern to ensure even tightness.
Reconnect the battery.
