The Cosa was one of the first shifting scooters ever to have a hydraulic integral brake system. Via the brake pedal operated by foot, both wheels are braked with hydraulic drum brakes.
The hand lever brake on the handlebars acts solely on the front wheel. It is, however, only intended as an emergency brake or holding brake for starting on inclines and not as a service brake. With this technology Piaggio wanted to bring even more inexperienced two-wheelers onto their vehicles and make it easier for them to change over to familiar car technology.
Like all hydraulic brakes, COSA system components are also subject to the ravages of time. If maintenance is neglected, the aggressive, hygroscopic (water-attracting) brake fluid causes the hydraulic cylinders of the brake to corrode and a total failure of the brake is pre-programmed.
In order to keep the classic of tomorrow, the COSA, mobile we have managed to provide almost all wear parts of the Cosa brake system in high quality at a reasonable kit price:
- Main brake cylinder
- Brake cylinder front
- Brake cylinder rear
- Brake pad set front
- Brake pad set rear
This allows the Cosa brake to be repaired reliably and permanently.
In addition, we also offer brake lines, brake drums and the brake pressure regulator as well as small parts.
