Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, torque wrench, brake cleaner, dial indicator (for rotor measurement).
Safety Warnings: Ensure the vehicle is on a flat surface and securely supported on jack stands before beginning any work.

2. Inspect and Replace Brake Components

Remove Wheel:
- Loosen the lug nuts slightly while the vehicle is on the ground.
- Lift the vehicle using a jack and securely place it on jack stands.
- Remove the lug nuts and take off the wheel.
Inspect Brake Rotors:
- Use a dial indicator to measure rotor runout. If runout exceeds manufacturer specifications (typically 0.002 inches), replace or resurface the rotor.
- Check for surface scoring or excessive rust.
Inspect Brake Pads:
- Examine pad thickness. Replace pads if they are worn below 3mm.
- Check for uneven wear patterns which may indicate caliper issues.
Replace Components:
- If rotors are warped, replace them with new rotors.
- Install new brake pads, ensuring they are oriented correctly.
- Compress the caliper piston using a brake caliper tool before installation if changing pads.

3. Reassemble and Torque

Reinstall Wheel:
- Place the wheel back onto the hub.
- Hand-tighten the lug nuts, then lower the vehicle back to the ground.
- Use a torque wrench to tighten the lug nuts to the manufacturer’s specifications (typically around 80-100 lb-ft).
Final Checks:
- Ensure all tools are removed from the engine bay and wheel area.
- Check brake fluid level and top off if necessary.
