Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Loosen lug nuts on the front wheels while the vehicle is still on the ground.

2. Lift the Vehicle

Use a hydraulic jack to lift the front of the vehicle securely.
Place jack stands under the frame for safety.
Remove the front wheels to access the brake components.

3. Remove Brake Calipers

Use a socket set to remove the caliper mounting bolts.
Carefully slide the caliper off the rotor; support it with a bungee cord to avoid stress on the brake line.
Inspect caliper pistons for any sticking or damage.

4. Inspect and Replace Brake Pads

Remove old brake pads from the caliper bracket.
Clean the caliper bracket and apply brake grease to the contact points of the new pads.
Install new brake pads, ensuring they are correctly seated.

5. Inspect and Replace Brake Rotors

If the rotors are damaged, remove the rotor by unscrewing any retaining screws and sliding it off the hub.
Install new rotors, ensuring they are torqued to the manufacturer's specifications (typically around 80-100 ft-lbs).
Apply anti-seize compound to the hub surface to prevent corrosion.

6. Reassemble Brake Components

Reattach the caliper over the new brake pads and rotor.
Reinstall caliper mounting bolts and tighten to the manufacturer's torque specifications (usually around 25-30 ft-lbs).
Reinstall the front wheels and snug the lug nuts.

7. Final Checks

Lower the vehicle off the jack stands.
Tighten the lug nuts to the manufacturer's specified torque (typically 100-150 ft-lbs).
Pump the brake pedal several times to ensure the pads seat properly against the rotors.
