Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a flat surface and engage the parking brake.

2. Wheel Removal

Loosen the lug nuts on the front wheels using a lug wrench.
Raise the vehicle using a jack and secure with jack stands.
Remove the front wheels completely.

3. Brake Rotor and Pad Replacement

Remove Caliper:
- Use a socket set to remove the caliper mounting bolts.
- Carefully slide the caliper off the rotor and support it with a bungee cord, avoiding stress on the brake line.
Inspect and Replace Brake Pads:
- Remove old brake pads from the caliper bracket.
- Check the caliper bracket for wear and clean any debris.
- Install new brake pads into the caliper bracket.
Remove and Replace Rotors:
- If rotors are warped or worn, remove the retaining screws (if applicable).
- Slide the rotor off the hub and replace it with a new rotor.
- Ensure the new rotor is clean and free of grease.
Reinstall Caliper:
- Reposition the caliper over the new rotor and pads.
- Torque the caliper bolts to the manufacturer’s specifications (usually 20-30 ft-lbs).

4. Wheel Installation

Reinstall the front wheels and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and tighten the lug nuts to the manufacturer’s specifications (usually 75-90 ft-lbs) in a crisscross pattern.
