Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery to prevent any electrical shorts.

2. Remove Wheel

Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts using a socket wrench and take off the wheel.

3. Inspect and Replace Brake Components

A. Inspect Brake Rotors

Remove the caliper by unscrewing the bolts (usually 12mm or 14mm).
Take off the rotor; inspect for warping with a dial indicator or straight edge.
If warped, replace the rotor with a new one.

B. Check Brake Pads

Inspect the thickness of the brake pads. If they are below 3mm, replace them.
Ensure that the pads are wearing evenly; if uneven, inspect caliper function.

C. Reassemble Brakes

Clean the caliper bracket and apply brake grease to the contact points.
Reinstall the rotor and caliper, tightening bolts to the manufacturer's torque specifications (typically around 25-30 Nm).
Reinstall the wheel and torque the lug nuts to proper specifications (usually 120 Nm).

4. Test Drive and Evaluate

Lower the vehicle and reconnect the battery.
Perform a test drive, applying the brakes at various speeds to check for vibrations.
