Solution

1. Preparation

Tools Required: Socket set, jack and jack stands, lug wrench, brake cleaner, torque wrench.
Safety Warnings: Ensure the vehicle is on a flat surface and secured with wheel chocks before lifting.

2. Remove Wheel

Loosen lug nut bolts slightly while the vehicle is on the ground.
Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect Brake Components

Check brake pads for wear; if the pad material is less than 1/8 inch, replace them.
Measure the thickness of the brake rotors using a micrometer; if they are below manufacturer specifications, they must be replaced or resurfaced.
Inspect calipers for any signs of fluid leaks or sticking; ensure they move freely when operated.

4. Replace Brake Pads and/or Rotors

If brake pads are worn, remove the caliper by unscrewing the mounting bolts.
Slide the caliper off and support it without putting stress on the brake line.
Remove the old brake pads and install new ones, ensuring they are correctly positioned.
If rotors need replacement, remove the old rotor by unscrewing the retaining screws and sliding it off the hub.
Install the new rotor, ensuring it is aligned correctly.

5. Reassemble and Lower Vehicle

Reattach the brake caliper over the new pads and tighten the caliper bolts to manufacturer's torque specifications.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and tighten lug nuts in a star pattern to the specified torque.
