Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery for safety.

2. Remove Wheel

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

3. Inspect and Replace Brake Pads

Inspection:
- Check the thickness of the brake pads. If they are below 3mm, they need replacement.
Replacement:
- Remove the caliper bolts using a socket wrench.
- Carefully slide the caliper off the brake rotor and support it using a bungee cord to avoid strain on the brake line.
- Remove the old brake pads from the caliper bracket.
- Install new brake pads, ensuring they are oriented correctly and seated properly against the caliper bracket.
- Compress the caliper piston using a C-clamp to make room for the new pads.

4. Inspect and Replace Brake Rotors (if necessary)

Inspection:
- Measure the rotor thickness using a micrometer. If below minimum specification or if warped, proceed to replace.
Replacement:
- Remove the caliper bracket by unscrewing its bolts.
- Slide off the old rotor from the hub.
- Clean the hub surface with brake cleaner to ensure proper mounting of the new rotor.
- Install the new rotor, securing it in place.

5. Reassemble and Test

Reattach the caliper bracket and caliper, ensuring all bolts are torqued to manufacturer's specifications (typically around 80 ft-lbs for caliper bolts).
Reinstall the wheel and lug nuts, and lower the vehicle.
Reconnect the battery.
