Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Gather safety equipment: gloves and safety glasses.

2. Lift and Secure the Vehicle

Use a jack to lift the front of the vehicle.
Secure with jack stands to prevent accidental lowering.

3. Remove the Wheel

Remove the lug nuts using a socket wrench.
Take off the wheel to access the braking components.

4. Inspect and Replace Brake Components

Brake Rotor Inspection:
- Check rotors for thickness and warping.
- If warped, replace rotors.
- Torque new rotors to manufacturer specifications (typically around 100-130 ft-lbs).
Brake Pad Replacement:
- Remove caliper bolts using a socket wrench.
- Slide the caliper off and support it without stress on the brake line.
- Remove old pads and install new ones, ensuring proper orientation.
- Reinstall the caliper and torque bolts to manufacturer specifications.

5. Reassemble and Lower Vehicle

Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands.
Torque the lug nuts to manufacturer specifications (usually around 80-100 ft-lbs).
