Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Tools Required: Jack, jack stands, lug wrench, socket set, torque wrench, dial indicator.

2. Remove Wheel

Loosen the lug nuts slightly while the vehicle is 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 and Replace Brake Pads and Rotors

Inspect Brake Pads:
- Check the thickness of the brake pads; replace if worn below the manufacturer’s specifications (typically less than 3mm).
Inspect Brake Rotors:
- Use a dial indicator to measure the rotor run-out; replace if warping exceeds allowable limits (usually 0.002 inches).
Replace Rotors (if necessary):
- Remove caliper bolts, take off the caliper, and hang it using a wire (do not let it dangle from the brake line).
- Remove the rotor screws if applicable and slide the rotor off the hub.
- Install the new rotor and torque the screws to manufacturer specifications.

4. Reassemble and Torque Components

Reinstall the brake caliper and torque the caliper bolts to the manufacturer's specifications.
Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts in a criss-cross pattern to the manufacturer’s specified torque value (usually around 76 ft-lbs).
