Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety while working on the braking system.

2. Inspect and Remove Wheel

Use a lug wrench to loosen the lug nuts, then raise the vehicle using a jack and secure it with jack stands.
Completely remove the lug nuts and take off the wheel.

3. Inspect Brake Components

Brake Pads: Remove the caliper bolts using a socket wrench, then slide off the caliper. Check the brake pads for thickness and even wear. Replace if necessary.
Brake Rotors: Remove the rotor by removing any retaining screws or clips. Inspect for warping using a dial indicator. If warped beyond specifications, replace the rotor.

4. Replace Brake Components (if necessary)

If brake pads or rotors are worn, install new components:
- Brake Pads: Apply brake grease to the backing of the new pads and install them in the caliper bracket.
- Brake Rotors: Install new rotors and secure them with retaining screws or clips.

5. Reassemble and Test

Reattach the caliper over the new pads and torque the caliper bolts to manufacturer specifications.
Reinstall the wheel and lug nuts, then lower the vehicle.
Reconnect the negative battery terminal.
