Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety glasses and gloves for protection.

2. Remove Wheel

Use a jack to lift the vehicle and securely place jack stands.
Remove the wheel lug nuts using a socket wrench and carefully take off the wheel.

3. Inspect and Remove Brake Pads

Locate the brake caliper and remove the caliper bolts using a socket wrench.
Carefully slide the caliper off the rotor and support it with a bungee cord to avoid stress on the brake line.
Remove the old brake pads from the caliper bracket.

4. Install New Brake Pads

Compare new brake pads with old ones to ensure proper fit.
Apply brake grease to the back of the new brake pads to prevent squeaking.
Install the new brake pads into the caliper bracket.

5. Reassemble Brake System

Reposition the caliper over the new pads and tighten the caliper bolts to the manufacturer's torque specifications (usually around 25-35 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Test Brakes

Lower the vehicle and remove the jack stands.
Tighten the lug nuts to the specified torque (usually around 80-100 ft-lbs).
Pump the brake pedal several times to seat the new pads before driving.
