Inboard brake

Alfa Romeo GTV rear Inboard brake system

An inboard braking system is an automobile technology where the brakes are not located in the wheels, as is common today, but instead near the differential. Moving the brakes inboard reduces unsprung weight substantially, improving ride, handling and braking. This system was more common in the 1960s, found on such cars as the Jaguar E-Type and Citroën 2CV. The Hummer H1 is one of the few modern vehicles fitted with inboard brakes, although this addition was ostensibly to accommodate the Hummer's unusual gear-drive system used at each wheel.
