Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and turn on the hazard lights.
Wear safety glasses and gloves.

2. Raise the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on which brakes are affected.
Secure the vehicle on jack stands for safety.

3. Inspect and Remove Brake Components

Brake Rotor Inspection:
- Remove the wheel by loosening the lug nuts with a socket set.
- Inspect the rotors for any signs of warping or scoring; replace if necessary.
- Use a dial indicator to measure rotor run-out.
Brake Pad Inspection:
- Check the thickness of the brake pads; replace if below the manufacturer’s specifications.
- Look for uneven wear patterns that could indicate misalignment or suspension issues.

4. Replace Brake Components (if necessary)

Rotors:
- If rotors are warped, remove the caliper by unbolting it and slide the rotor off the hub.
- Install the new rotor and torque the caliper bolts to the manufacturer's specifications.
Brake Pads:
- Remove the old pads and replace them with new ones, ensuring they are seated correctly.
- Compress the caliper piston using a brake caliper tool before reinstallation.

5. Reassemble and Lower the Vehicle

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and torque the lug nuts to the specified value.

6. Test Drive

Conduct a test drive to ensure smooth braking and check for any vibrations.

Tools Required:

Jack and jack stands
Socket set
Torque wrench
Brake caliper tool
Dial indicator

Parts Required:

Brake rotors (if warped)
Brake pads (if worn)

Estimated Repair Time: 2-4 hours

Safety Warnings:

Disconnect the vehicle's battery before working on any electrical systems.
