The brake pad set typically includes two brake pads, one for each side of the rear axle, and they are designed to grip the surface of the brake rotor when the brake pedal is pressed. The brake pads are made of a high-friction material, such as ceramic or metallic compounds, and are designed to wear out over time.

When it's time to replace the brake pads, it's important to use a set that is specifically designed for your vehicle's make and model. The rear brake pads should be replaced as a set to ensure even wear and optimal performance.

It's important to keep the rear brake pads in good condition to ensure safe and effective braking performance. Neglecting to replace worn brake pads can result in reduced stopping power and longer stopping distances, which can be dangerous in emergency situations.
