We are often working with vehicles so heavy that despite being relatively slow, they still need up to 30 times the brake torque used by racing cars, requiring calipers made from cast iron rather than aluminium. Even on a vehicle weighing dozens of tonnes it’s crucial our brakes play their part in not just slowing and stopping the vehicle but helping achieve the overall design objectives. For instance our heaviest cast iron caliper weighs 26kg, but it does the job of two 18kg calipers, saving 10kg of unsprung mass per wheel. On the Patria AMV we saved 800g per caliper by hollowing away redundant material, which may not sound like much on a 35 tonne vehicle, but every gramme saved means more equipment can be carried, or a greater range achieved or a reduction in fuel costs. It all counts, and that is the attention to detail you can expect from Alcon.
