A brake system for a heavy vehicle, the brake system comprising a first brake controller arranged to control braking on a first wheel and a second brake controller arranged to control braking on a second wheel based on respective configured wheel slip limits and respective brake torque requests. The second brake controller is arranged to control braking on the second wheel, where the first brake controller and the second brake controller are interconnected via a backup connection, the spare connection is arranged to allow one of the first brake controller and the second brake controller to undertake wheel brake control of the other of the first brake controller and the second brake controller in the event of a brake controller failure, the brake system comprising a control unit arranged to respond to the brake controller failure, a configured wheel slip limit ([lambda] CON, 710) associated with the faulty brake controller is reduced (601) to a reduced wheel slip limit ([lambda] LOW, 730). 一种用于重型车辆的制动系统，该制动系统包
