Solution

1. Preparation

Gather necessary tools and materials.
Ensure the vehicle is parked on a level surface, and set the parking brake.
Wear safety glasses and gloves for protection.

2. Lift the Vehicle

Use a jack to lift the vehicle and place jack stands securely under the vehicle.
Remove the wheels using a socket set.

3. Remove Brake Caliper

Use a socket set to remove the caliper bolts.
Carefully slide the caliper off the brake rotor and support it with a bungee cord or rope to avoid straining the brake line.

4. Inspect and Replace Brake Pads

Remove the old brake pads from the caliper bracket.
Compare the thickness of the old pads to the new ones; replace if worn down.
Clean the caliper bracket and apply brake grease to the backing of the new pads to prevent squeaking.
Install the new brake pads into the caliper bracket.

5. Reassemble Components

Reattach the brake caliper over the new pads and tighten the caliper bolts to the manufacturer’s specified torque (usually around 25-30 lb-ft).
Reinstall the wheel and lug nuts; tighten to the recommended torque (typically around 80-100 lb-ft).

6. Lower the Vehicle and Test

Carefully lower the vehicle off the jack stands.
Pump the brake pedal several times to ensure proper pad seating.
Conduct a test drive to ensure brakes are functioning correctly.
