Solution

1. Preparation

Gather tools and parts before starting.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Wear safety gloves and goggles.

2. Raise the Vehicle

Use a floor jack to lift the front or rear of the vehicle as needed.
Secure with jack stands for safety.

3. Remove the Wheel

Use a socket set to remove the lug nuts and take off the wheel.
Store lug nuts in a safe place for reinstallation.

4. Inspect and Replace Brake Rotors (if necessary)

Inspect: Use a dial indicator to measure rotor runout.
Replace:
- If warping is detected, remove the brake caliper by unbolting it.
- Remove the rotor from the hub.
- Install new rotors, ensuring they are properly aligned and seated.
- Torque the rotor retaining screws to manufacturer specifications.

5. Inspect and Replace Brake Pads (if necessary)

Inspect: Check brake pad thickness; if below 3mm, they need replacement.
Replace:
- Remove the caliper bracket to access brake pads.
- Slide out old pads and replace with new ones.
- Ensure caliper pistons are retracted for proper fit.
- Reassemble the caliper and torque to manufacturer specifications.

6. Reinstall Wheel and Lower Vehicle

Place the wheel back onto the hub and hand-tighten lug nuts.
Lower the vehicle from the jack stands and torque lug nuts to the specified value.

7. Test Drive

Conduct a test drive to ensure the problem is resolved and brakes function smoothly.
