Solution

1. Preparation

Gather tools and parts required for the job.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.
Disconnect the battery if needed for safety.

2. Remove Wheel

Loosen lug nuts using a socket wrench.
Lift the vehicle with a jack and secure it on jack stands.
Remove the wheel to access brake components.

3. Inspect and Replace Brake Rotors (if necessary)

If rotor runout exceeds specifications (typically 0.002 inches), replace the rotors.
- Remove caliper bolts using a socket wrench.
- Carefully detach the brake caliper and suspend it using a bungee cord.
- Remove the rotor by unscrewing the retaining screws or using a hammer if it’s stuck.
- Install new rotors, ensuring they are clean and free of oil.

4. Inspect and Replace Brake Pads (if necessary)

Check the condition of brake pads; if they are worn down to the indicators, replace them.
- Remove the old pads from the caliper bracket.
- Apply brake grease to the backing of new pads and install them.

5. Reassemble Components

Reattach the caliper over the new pads and torque the caliper bolts to manufacturer specifications (typically around 25-30 Nm).
Reinstall the wheel and torque the lug nuts to the specified value (usually 120 Nm).

6. Test Brakes

Reconnect the battery and lower the vehicle.
Test the brake system by applying the brakes at low speeds to ensure proper function before taking it on a test drive.
