Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface and secured with wheel chocks.
Wear safety gloves and goggles for protection.

2. Remove Wheels

Loosen the lug nuts on the front wheels using a lug wrench.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheels.

3. Inspect and Replace Brake Pads

Remove the brake caliper by unscrewing the caliper bolts with a socket set.
Gently lift the caliper away from the rotor and secure it with a bungee cord to avoid straining the brake line.
Remove the old brake pads from the caliper bracket.
Check the caliper slide pins for lubrication; apply brake grease if necessary.
Install new brake pads, ensuring they are seated properly in the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

If rotors are warped or uneven, remove them by unscrewing the rotor retaining screws.
Install new rotors and torque them to the manufacturer's specifications (usually around 10-15 ft-lbs).
Ensure that the new rotor surface is clean before installation.

5. Reassemble Braking System

Reattach the brake caliper over the new pads and rotor.
Tighten the caliper bolts to the manufacturer's torque specification (typically around 25-30 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Final Checks

Lower the vehicle from the jack stands.
Tighten the lug nuts in a star pattern to the specified torque (usually around 80-100 ft-lbs).
Pump the brake pedal several times to ensure proper brake pad seating.
