A brake system for a road vehicle, the brake system comprising an actuator, a mechanical linkage, a first part associated with a chassis of the vehicle and a second part associated with a wheel support part of the vehicle and moveable relative to the chassis, wherein the mechanical linkage is connected to the first part and second part to cause movement of the actuator in response to movement of the chassis relative to the wheel support part, wherein a suspension element is disposed between the chassis and the wheel support part, the suspension element being controllable by supplying pneumatic or hydraulic pressure thereto to provide ride cushioning and, to apply a braking force, being controllable to lower the chassis relative to the wheel support part such that the weight of the vehicle is transmitted via the mechanical linkage to the actuator to provide a braking force.
