Solution

1. Preparation

Gather tools and safety gear (gloves, goggles).
Park the vehicle on a level surface and engage the parking brake.
Loosen the lug nuts on the front wheels slightly before lifting the vehicle.

2. Lift the Vehicle

Use a floor jack to lift the front of the vehicle.
Secure with jack stands for safety.

3. Remove Wheel

Remove the lug nuts completely and take off the front wheel.
Repeat for the other side if necessary.

4. Inspect and Replace Brake Pads

Check the brake pads for thickness; replace if less than 1/8 inch.
If replacing, remove the caliper bolts with a socket wrench and carefully slide the caliper off.
Remove old pads from the caliper bracket.
Install new brake pads, ensuring they are properly aligned and seated.

5. Inspect and Resurface/Replace Rotors

Measure rotor thickness and check for warping or scoring.
If warped or below minimum thickness, remove the rotor by unbolting it from the hub.
Resurface or replace the rotor as necessary, ensuring it is clean and free of debris.

6. Reassemble Braking System

Reattach the caliper over the new pads and secure it with the caliper bolts.
Repeat for the other side if applicable.
Reinstall the wheel and tighten the lug nuts to the manufacturer’s specified torque.

7. Lower Vehicle and Test

Carefully lower the vehicle back to the ground.
Torque the lug nuts to the specified value.
Test the brake pedal to ensure it feels firm before taking the vehicle for a test drive.
