Solution

1. Preparation

Tools Required: Jack and jack stands, wheel chocks, lug wrench, socket set, torque wrench, brake cleaner, and safety glasses.
Sub-steps:
- Park the vehicle on a level surface and engage the parking brake.
- Place wheel chocks behind the rear wheels for safety.
- Gather all necessary tools and parts.

2. Remove Wheel

Sub-steps:
- Loosen the lug nuts slightly while the vehicle is still on the ground.
- Raise the vehicle using a jack and secure it with jack stands.
- Completely remove the lug nuts and take off the wheel.

3. Inspect Brake Components

Sub-steps:
- Inspect the brake pads for thickness; replace if less than 3mm.
- Check rotors for any visible damage or uneven wear; replace if necessary.
- Examine calipers for any signs of leakage or sticking.

4. Replace Brake Pads and Rotors (if necessary)

Sub-steps:
- Remove the caliper mounting bolts using a socket set.
- Slide the caliper off the rotor and support it with a bungee cord (do not let it hang by the brake line).
- Remove the old brake pads and install new ones, ensuring they are properly aligned.
- If replacing rotors, remove the old rotor by unscrewing any retaining screws if applicable, and install the new rotor.
- Reinstall the caliper and torque mounting bolts to manufacturer specifications (typically 20-30 ft-lbs, but check the service manual).

5. Reassemble and Test

Sub-steps:
- Reinstall the wheel and hand-tighten the lug nuts.
- Lower the vehicle off the jack stands and tighten the lug nuts to the specified torque (typically 70-80 ft-lbs).
- Pump the brake pedal a few times to seat the brake pads before test driving.
