Solution

1. Preparation

Gather tools and materials.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Gather necessary tools: jack, jack stands, lug wrench, brake cleaner, torque wrench, micrometer (for measuring rotors).

2. Remove Wheel

Loosen the lug nuts using the lug wrench.
Lift the vehicle using the jack and secure it on jack stands.
Completely remove the lug nuts and take off the wheel.

3. Inspect Brake Components

Visually inspect the brake pads for thickness; replace if worn below 3 mm.
Measure rotor thickness with a micrometer; replace if below manufacturer specifications (usually around 24 mm for most rotors).
Check for any signs of uneven wear or scoring on the rotors.

4. Replace Brake Pads (if necessary)

Remove the caliper by unscrewing the caliper bolts.
Slide the caliper off the rotor and support it to avoid straining the brake line.
Remove the old brake pads from the caliper bracket.
Install new brake pads into the caliper bracket.
Compress the caliper piston using a brake caliper tool until it fits over the new pads.

5. Replace Rotors (if necessary)

Remove the caliper bracket if replacing rotors.
Unscrew and remove the rotor from the hub.
Install the new rotor and secure it in place.
Reinstall the caliper bracket and caliper over the new rotor.

6. Reassemble the Wheel

Place the wheel back onto the hub.
Hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the manufacturer's specifications (usually around 100-120 ft-lbs).
