Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, socket set, brake cleaner, torque wrench.
Safety Warnings: Ensure the vehicle is on a flat surface, engage the parking brake, and wear safety goggles.

2. Lift the Vehicle

Use the jack to raise the front or rear of the vehicle, depending on which brakes are being serviced.
Secure the vehicle on jack stands to ensure stability.

3. Remove Wheel

Use the lug wrench to remove the lug nuts and take off the wheel.
Place the wheel aside for reinstallation later.

4. Inspect and Replace Brake Pads

Sub-steps:
- Remove the caliper bolts using the socket set.
- Carefully slide the caliper off the rotor, supporting it with a bungee cord or rope to avoid stress on the brake line.
- Remove the old brake pads from the caliper bracket.
- Clean the caliper bracket and rotor with brake cleaner to remove dust and debris.
- Install new brake pads in the caliper bracket, ensuring they are seated properly.

5. Inspect and Replace Brake Rotors (if necessary)

If rotors are scored or excessively worn, remove them by unbolting from the hub.
Install new rotors, ensuring they are properly aligned and torqued to manufacturer specifications (typically around 100-120 ft-lbs).

6. Reassemble Components

Slide the caliper back over the new brake pads and rotor.
Install and torque the caliper bolts to manufacturer specifications (typically around 25-30 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.

7. Lower the Vehicle

Carefully lower the vehicle back to the ground using the jack.
Torque the lug nuts to manufacturer specifications (typically around 100-150 ft-lbs).
