Solution

1. Preparation

Gather necessary tools and parts.
Park vehicle on a flat surface and engage the parking brake.
Raise the vehicle using a jack and secure it with jack stands.

2. Remove Wheel

Use a socket set to remove the lug nuts and take off the wheel.
Ensure the wheel is stored safely to prevent damage.

3. Inspect and Replace Brake Components

a. Brake Pads

Remove the caliper bolts with a socket wrench.
Slide the caliper off the rotor and support it with a wire or bungee cord (do not let it hang by the brake line).
Remove old brake pads and inspect for wear. Replace if thickness is below manufacturer specifications.
Install new brake pads, ensuring they are properly seated.

b. Brake Rotors

Check rotor surfaces for warping using a dial indicator or straight edge.
If warped, remove the rotor by unscrewing the rotor retaining screws (if applicable).
Replace with new rotors if necessary, ensuring they are installed in the correct orientation.

4. Reassemble Components

Reattach the caliper over the new brake pads and torque the caliper bolts to manufacturer specifications (typically 20-30 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts in a star pattern to the specified torque (typically 75-85 ft-lbs).

5. Final Checks

Pump the brake pedal to ensure proper pressure before test driving.
Inspect for any leaks around the brake components.
