Solution

1. Preparation

Gather necessary tools and parts.
Ensure vehicle is on a flat surface and secure with wheel chocks.
Raise the vehicle using a jack and support it with jack stands.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts while the wheel is still on the ground.
Lift the vehicle and remove the lug nuts completely.
Take off the wheel to access the brake components.

3. Inspect and Replace Brake Rotors

Locate the brake rotor and check for warping or scoring.
If damaged, remove the caliper by unbolting it (usually requires a socket set).
Remove the rotor by pulling it off the hub. If stuck, tap gently with a rubber mallet.
Install new rotors, ensuring they are clean and free of oil/grease.
Torque the rotor retaining screws (if applicable) to manufacturer specifications.

4. Inspect and Replace Brake Pads

Check the thickness of the brake pads. If below 3mm, replace them.
Remove the old pads from the caliper bracket.
Apply brake grease to the backing of the new pads to prevent noise.
Install new pads in the caliper bracket.

5. Reassemble and Test

Reattach the caliper over the newly installed pads and torque the bolts to the manufacturer's specification.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle back to the ground and torque the lug nuts to the manufacturer's specifications.
Test the brakes by applying them gently to ensure proper installation and function.
