The Genuine Porsche Brake Fluid Level Switch (part number 95835537700) is a component used in Porsche vehicles to monitor the level of brake fluid in the reservoir. It is a small, electronic switch that is connected to the brake fluid reservoir and sends a signal to the vehicle's computer when the brake fluid level is low. This allows the driver to be alerted when the brake fluid needs to be refilled, preventing potential brake failure. The switch is designed specifically for Porsche vehicles and is made with high-quality materials to ensure reliable performance.
