Solution

1. Preparation

Tools Needed: Jack, jack stands, lug wrench, socket set, brake cleaner, safety glasses, gloves.
Safety Warning: Always ensure the vehicle is on a stable surface and secured with jack stands before starting.

2. Remove Wheel Assembly

Loosen the lug nuts on the wheel using a lug wrench.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Components

Brake Pads

Remove the caliper by unbolting it from the bracket.
Slide the caliper off the rotor, being careful not to stress the brake line.
Inspect the brake pads for wear; if they are worn down to the metal or below the recommended thickness, replace them.
Install new brake pads, ensuring they slide into place properly.

Brake Rotors

Check the brake rotor surface for any grooves or scoring; if damaged, they should be resurfaced or replaced.
If replacing, remove the rotor by unbolting it from the hub.
Install new rotors, ensuring they are properly seated.

4. Reassemble and Test

Reattach the caliper over the new pads and torque the bolts to manufacturer specifications (typically around 25-35 ft-lbs).
Reinstall the wheel, replace the lug nuts, and torque them to the manufacturer's specification (usually around 76-86 ft-lbs).
Lower the vehicle and ensure everything is secure.

5. Brake Fluid Inspection (if applicable)

Check brake fluid level in the reservoir; top off with the recommended fluid type (DOT 3 or DOT 4).
Inspect for any leaks from the brake line or calipers.
