Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, torque wrench, brake cleaner, safety goggles, gloves.
Park the vehicle on a flat surface and engage the parking brake.
Wear safety goggles and gloves for protection.

2. Raise the Vehicle

Use the lug wrench to loosen the lug nuts on the front wheels but do not remove them completely.
Raise the front of the vehicle using a jack and secure it with jack stands.
Remove the front wheels.

3. Inspect and Replace Brake Pads

Sub-steps:
- Remove the caliper bolts using a socket wrench.
- Carefully slide the caliper off the rotor; support it with a bungee cord or hang it to avoid stress on the brake line.
- Inspect the brake pads for wear; if less than 1/4 inch thick, replace them.
- Remove the old brake pads from the caliper bracket.
- Clean the caliper bracket and apply brake grease to the backing of the new pads.
- Install the new brake pads into the caliper bracket.

4. Check and Replace Brake Rotors (if needed)

Sub-steps:
- Inspect the rotors for any scoring or warping.
- If damaged, remove the rotor by unbolting it from the wheel hub.
- Install new rotors, ensuring they are clean and free from grease.
- Torque the rotor bolts to manufacturer specifications.

5. Reassemble the Brake System

Slide the caliper over the new pads and rotor.
Reinstall and torque the caliper bolts to manufacturer specifications.
Reinstall the wheel and tighten the lug nuts in a crisscross pattern.

6. Lower the Vehicle

Remove the jack stands and lower the vehicle back to the ground.
Tighten the lug nuts to the specified torque.
