Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, socket set, torque wrench, brake cleaner, safety goggles, gloves.
Ensure the vehicle is parked on a level surface and the engine is off.
Engage the parking brake.

2. Lift the Vehicle

Loosen the lug nuts on the front wheels before raising the vehicle.
Use a jack to lift the vehicle and secure it with jack stands.
Completely remove the lug nuts and take off the front wheels.

3. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the brake caliper bolts using a socket set.
2. Carefully slide the caliper off the rotor, ensuring to support it to avoid straining brake lines.
3. Remove the old brake pads from the caliper bracket.
4. Inspect the brake pad backing plates for damage.
5. If worn, install new brake pads into the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
1. Check the rotor for scoring or warping. If damaged, remove the rotor by unscrewing the retaining screws (if applicable).
2. Replace it with a new rotor, ensuring it is clean and free of oil.
3. Torque the retaining screws to the manufacturer’s specifications (typically around 10-15 ft-lbs).

5. Reassemble and Test

Sub-steps:
1. Reattach the caliper over the new pads and rotor, ensuring it is seated correctly.
2. Tighten the caliper bolts to the specified torque (usually around 25-30 ft-lbs).
3. Reinstall the wheels and torque the lug nuts in a star pattern to the manufacturer’s specifications (usually around 75-85 ft-lbs).
4. Remove the jack stands and lower the vehicle.
