Abstract
A pneumatic brake arrangement for a combination vehicle comprises park brakes, an air production module, and a first pneumatic control line pneumatically controlling the park brakes of the trailer from the tractor. This control line is divided into an upstream portion mounted on the tractor and a downstream portion mounted on the trailer. The first and second portions respectively include a first coupling head and a second coupling head. The arrangement can actuate all park brakes at the same time, based on a braking order received from the tractor cabin. The first coupling head is a vented coupling head, which allows air present in the upstream pneumatic control line portion to be exhausted when the first and second coupling heads are not connected.
