Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, brake cleaner, torque wrench.
Raise the vehicle securely on jack stands and remove the wheel.
Ensure all tools and safety equipment are on hand.

2. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the brake caliper by loosening the caliper bolts using a socket set.
2. Support the caliper with a bungee cord or similar device to avoid stress on the brake line.
3. Remove the old brake pads from the caliper bracket.
4. Inspect the caliper for any signs of damage or sticking.
5. Replace with new brake pads, ensuring they are installed correctly in the caliper bracket.

3. Inspect and Resurface/Replace Rotors

Sub-steps:
1. Remove the brake rotor from the hub.
2. Inspect for warping or scoring using a straight edge or machinist's ruler.
3. If necessary, either resurface the rotor or replace it with a new one.
4. Clean the rotor surface with brake cleaner before reinstallation.

4. Check and Lubricate Caliper Components

Sub-steps:
1. Lubricate the caliper slides and pins with high-temperature brake grease.
2. Ensure the caliper hardware (shims, clips) is intact and properly positioned.
3. Reinstall the caliper over the new brake pads.

5. Reassemble and Test

Sub-steps:
1. Reinstall the wheel and hand-tighten the lug nuts.
2. Lower the vehicle from the jack stands.
3. Torque the lug nuts to the manufacturer’s specifications.
4. Pump the brake pedal several times to ensure proper pad contact with the rotor.
