Solution

1. Preparation

Tools Required: Floor jack, jack stands, lug wrench, brake cleaner, torque wrench, socket set.
Park the vehicle on a flat surface, engage the parking brake, and turn off the ignition.
Allow the vehicle to cool down if it has been recently driven.

2. Raise the Vehicle

Loosen the lug nuts on the front wheels slightly while the vehicle is still on the ground.
Use a floor jack to lift the front of the vehicle and support it with jack stands.
Remove the lug nuts and take off the front wheels.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using the appropriate socket.
Carefully slide the caliper off the rotor. Do not let it dangle by the brake line.
Inspect the brake pads for thickness. If they are worn down (less than 3 mm), replace them.
If replacing, remove the old pads and install new ones, ensuring they are aligned correctly.

4. Inspect and Resurface or Replace Rotors

Examine the brake rotors for any grooves or scoring. If damaged, consider having them resurfaced or replaced.
Clean the rotors with brake cleaner to remove dust and debris.
If resurfacing, check the manufacturer's specifications for minimum thickness before proceeding.

5. Reassemble and Torque

Reinstall the caliper over the new brake pads and ensure it is seated correctly.
Tighten the caliper bolts to the manufacturer’s specified torque setting (typically 25-30 ft-lbs).
Reattach the wheel and hand-tighten the lug nuts.

6. Lower the Vehicle

Carefully lower the vehicle back to the ground using the floor jack.
Use the torque wrench to tighten the lug nuts to the manufacturer’s specified torque (usually 75-80 ft-lbs).
