2. Jack up the vehicle and secure it on jack stands.
3. Remove the lug nuts completely and take off the wheel.
Tools Required: Jack, jack stands, lug wrench.

3. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the caliper bolts and slide the caliper off the rotor.
2. Remove old brake pads from the caliper bracket.
3. Inspect the caliper for damage and ensure it moves freely.
4. Install new brake pads, ensuring they are seated properly.
5. Reattach the caliper and torque the bolts to manufacturer specifications.
Tools Required: Socket set, torque wrench, brake cleaner.
Safety Warnings: Wear gloves and eye protection while working with brake components.

4. Inspect and Resurface/Replace Rotors

Sub-steps:
1. Check the rotor thickness and surface condition.
2. If warped, either resurface the rotors or replace them if beyond specifications.
3. Clean the rotor surface with brake cleaner before reinstallation.
4. Reinstall the rotor and ensure it is secured properly.
Tools Required: Brake rotor gauge, impact wrench (if applicable).
Safety Warnings: Ensure rotors are cool before handling.

5. Reassemble and Test

Sub-steps:
