Composite brake
A compound brake is a braking system that can simultaneously decelerate several wheels or axles with one brake lever. The term composite brake first appears in connection with the Kunze-Knorr-Bremse , a compressed air brake for freight, passenger and express trains - later as a generic term for the four-wheel brake in cars.
The basic idea of the composite brake is that an optimal braking effect is only achieved if all wheels are decelerated simultaneously with one lever movement. In multi-lane motor vehicles with dual-circuit braking systems and modern motorcycles with sidecars , it is legally stipulated to brake all / several wheels simultaneously with a brake lever / pedal, otherwise the legally prescribed mean full deceleration values of at least 5.0 m / s² cannot be achieved.

Since 1926, two independent braking systems have been prescribed for motorcycles in Germany. Since then, it has been common practice to brake the front wheel with a hand lever and the rear wheel brake with a foot lever. Because the composite brake is not mandatory for motorcycles, the term is only used today for motorcycles that have it optionally installed. The first tests with a composite brake were made by Tornax in 1928 , and in 1930 in the Victoria KR 50 model . In 1976, the motorcycle manufacturer Moto Guzzi brought the first mass-produced composite brake onto the market with the 750 S3 model, where it was called "integral brake". The 6-cylinder Benelli 900 Sei (1978 to 1989) was also equipped with it. The motorcycle manufacturer Honda has also been installing composite brakes since 1993, with ABS since 1996 ; Honda calls the system CBS-ABS . BMW-Motorrad has been supplying a composite brake called Integral ABS since 2001 . Yamaha has been offering a composite brake with ABS for the new XTZ 1200 model since 2010.
