Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, brake cleaner, torque wrench, and safety glasses.
Safety Warnings: Always ensure the vehicle is on a flat surface and securely supported on jack stands before working under it.

2. Remove Wheel

Loosen the lug nuts with a lug wrench while the vehicle is still on the ground.
Raise the vehicle using a jack and securely support it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using a socket set and carefully slide the caliper off the rotor.
If the brake pads are worn down to the metal, replace them.
- Sub-step: Remove the old brake pads from the caliper bracket.
- Sub-step: Install new brake pads, ensuring they are properly seated.
If applicable, compress the caliper piston using a caliper tool to accommodate the new pads.

4. Inspect and Replace Rotors (if necessary)

Check the rotors for any visible damage or excessive wear.
If the rotor is scored or below the manufacturer's minimum thickness, it must be replaced.
- Sub-step: Remove the rotor by unscrewing the retaining screws (if applicable) and sliding it off the hub.
- Sub-step: Install the new rotor, ensuring it is aligned correctly and secure.

5. Reassemble and Test

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