18-inch brake system. The Estate R can reach speeds of up to 270 km/h and weighs just 1,630 kilograms, so it requires reliable and supreme deceleration when needed. At the front there is a new brake system with 18-inch discs – one inch (25.4 millimetres) larger than the brake discs in the predecessor model. The change in disc dimensions is from 340 x 30 millimetres to 357 x 34 millimetres. The new brake is built with pin discs and a brake pot made of aluminium, which reduces the weight by 600 grams on each side. A speed-dependent map in the electromechanical brake servo ensures precise brake control. When manoeuvring, the brakes respond particularly harmoniously; at high speeds, they are spontaneous and vehement, as desired. Thanks to precise optimisation in the high brake pressure range, the new brakes still permit very exact control even just before ABS intervention. This is due in no small part to the now larger brake master cylinder, which ensures a crisp yet refined response combined with sporty, short pedal travel which the driver definitely notices subjectively.
