Solution

1. Preparation

Secure the vehicle on a level surface and engage the parking brake.
Gather necessary tools and parts.
Disconnect the battery (optional for electrical safety).

2. Wheel Removal

Tools Required: Lug wrench, jack stands
Loosen the lug nuts slightly before lifting the vehicle.
Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Brake Component Inspection

Tools Required: Torque wrench, dial indicator
Inspect the brake rotors for warping. Use a dial indicator to measure any variations in rotor thickness.
Check the brake pads for wear. Replace if they are below 3mm thickness or unevenly worn.

4. Brake Rotor Replacement/Resurfacing

If rotors are warped, either replace them or have them resurfaced.
Sub-steps:
- Remove the caliper by loosening the caliper bolts.
- Slide the caliper off the rotor and secure it with a bungee cord to avoid strain on the brake line.
- Remove the rotor by unscrewing any retaining screws and sliding it off the hub.

5. Reassemble Components

Tools Required: Torque wrench
Install the new or resurfaced rotor onto the hub.
Reattach the caliper and torque bolts to manufacturer specifications (typically 25-35 ft-lbs).
Reinstall the wheel and torque lug nuts to the manufacturer’s specifications (typically 76-80 ft-lbs).

6. Final Checks

Reconnect the battery (if disconnected).
Lower the vehicle and perform a test drive to ensure brakes are functioning properly.
