Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety gloves and goggles for protection.

2. Remove Wheels

Use a jack to lift the vehicle and securely place jack stands.
Remove the lug nuts with a socket set and take off the wheels.

3. Inspect and Replace Brake Pads

Check the thickness of the brake pads; replace if below manufacturer specifications (typically 3 mm).
Remove the caliper bolts using a socket set.
Slide the caliper off the rotor and suspend it with a bungee cord (do not let it hang by the brake line).
Remove old brake pads and install new pads, ensuring they are aligned properly.

4. Inspect and Replace Brake Rotors

Check the rotors for warping using a runout gauge; replace if warped beyond specification (usually 0.002 inches).
Remove the rotor by unscrewing any retaining screws and sliding it off the hub.
Clean the hub surface and install new rotors, ensuring proper alignment.

5. Reassemble Components

Reattach the caliper over the new brake pads and torque caliper bolts to the manufacturer’s specifications (usually around 25-35 ft-lbs).
Reinstall the wheels and torque lug nuts in a crisscross pattern to ensure even pressure (usually 80-100 ft-lbs).

6. Test Brakes

Lower the vehicle and pump the brake pedal to ensure proper pad seating.
Perform a test drive at low speeds to check for any abnormal noises or vibrations.
