Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the battery for safety.

2. Wheel Removal

Tools Required: Socket set, torque wrench, wheel chocks.
Loosen the lug nuts slightly while the vehicle is on the ground (do not remove them yet).
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Components

Brake Rotors:
- Check for warping using a runout gauge.
- If warped beyond specifications, remove the rotor by unbolting it from the hub.
- Install new rotors, ensuring they are properly seated and torqued to manufacturer specifications (check service manual for torque values).
Brake Pads:
- Remove the caliper by unbolting it from the bracket.
- Inspect the brake pads for wear; replace if they are worn unevenly or below the minimum thickness.
- Lubricate caliper pins and install new brake pads, ensuring they fit snugly.

4. Reassemble and Reinstall Wheel

Reattach the caliper and ensure it is properly bolted.
Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer's specifications.

5. Brake System Check

Reconnect the battery.
Pump the brake pedal several times to ensure proper brake engagement before driving.
Check for any brake fluid leaks around the calipers and lines.
