Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, brake cleaner, torque wrench, socket set.
Sub-steps:
1. Park the vehicle on a flat surface and engage the parking brake.
2. Gather all necessary tools and parts for the repair.
3. Ensure the vehicle is cool before starting any work.

2. Lift the Vehicle

Sub-steps:
1. Loosen the lug nuts on the front wheels while the vehicle is still on the ground.
2. Use a jack to lift the vehicle and secure it on jack stands.
3. Remove the front wheels to access the brake components.

3. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the caliper bolts using a socket set and carefully slide the caliper off the rotor.
2. Remove the old brake pads from the caliper bracket.
3. Inspect the brake pads for wear; replace them if they are thinner than 3mm.
4. Apply brake grease to the back of the new brake pads to reduce noise.
5. Install the new brake pads into the caliper bracket.

4. Inspect and Resurface/Replace Rotors

Sub-steps:
1. Check the rotors for any grooves or scoring; if damaged, resurface or replace them.
2. Clean the rotor surface with brake cleaner to remove any dust or debris.
3. Reinstall the caliper over the new brake pads and torque the caliper bolts to manufacturer specifications (usually around 20-25 ft-lbs).

5. Reassemble and Lower Vehicle

Sub-steps:
1. Reattach the wheels and hand-tighten the lug nuts.
2. Lower the vehicle back to the ground using the jack.
3. Once on the ground, fully tighten the lug nuts in a crisscross pattern to the specified torque (usually around 76-83 ft-lbs).
