Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, torque wrench, brake rotor gauge, caliper gauge.
Raise the vehicle using a jack and secure it with jack stands.
Remove the wheel using a lug wrench.

2. Inspect Brake Rotors

Measure the thickness of the rotors using a rotor gauge.
Check for any signs of warping by placing a dial indicator on the rotor surface.
If the rotors are warped or below the minimum thickness, proceed to replace them.

3. Replace Brake Rotors (if necessary)

Tools Required: Brake cleaner, socket set, torque wrench.
Remove caliper bolts and carefully lift the caliper off the rotor, securing it with a bungee cord to avoid stress on the brake line.
Remove the old rotor by unscrewing any retaining hardware.
Clean the new rotor with brake cleaner to remove any protective coating.
Install the new rotor and reattach the caliper, ensuring all bolts are tightened to the manufacturer's specifications.

4. Inspect and Replace Brake Pads

Check the brake pads for wear using a caliper gauge.
If they are worn unevenly or below the minimum thickness, remove the old pads.
Install new brake pads, applying brake grease to the backing plates to reduce noise.
Ensure that the pads are seated properly and reassemble the caliper.

5. Reassemble and Torque Wheels

Replace the wheel and hand-tighten the lug nuts.
Lower the vehicle and use a torque wrench to tighten the lug nuts to the manufacturer's specified torque.
