Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Remove Wheel Assembly

Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts using a lug wrench and take off the wheel.

3. Inspect and Replace Brake Pads

Remove the caliper bolts and carefully slide the caliper off the rotor.
Inspect the brake pads for thickness; replace if they are worn down to 3mm or less.
To replace pads:
- Remove the old pads.
- Install new brake pads, ensuring they are properly seated in the caliper bracket.

4. Inspect and Resurface/Replace Rotors

Check the rotor using a dial gauge for warping (should be within manufacturer specifications).
If warped, either resurface the rotors or replace them.
If replacing, remove the rotor by unscrewing the retaining screws and pulling it off the hub.

5. Reassemble Components

Reattach the caliper over the new pads and torque the caliper bolts to manufacturer specifications.
Reinstall the wheel and torque the lug nuts in a star pattern to the specified value.
Lower the vehicle back to the ground.
