2135601 9400326 PCTABS00030 A fluid control system for use with a tractor trailer brake system comprises a branch conduit (19, 25) which is to be connected to a pressure supply line (20) and a control line (22) to enable priming of the control line (20) so that signals generated upon application of the vehicle brake pedal are more quickly transmitted to the trailer brakes to overcome problems associated with delay in application of the trailer brakes. An electrically operated solenoid valve (11) is provided for controlling fluid flow through the branch conduit so that upon application of the vehicle brake pedal the solenoid valve is operated to open the branch conduit to allow pressurised fluid to flow from the supply line (20) to the control line (22) for a predetermined time period to prime the control line (22). Pressurised fluid from the branch supply conduit is directed longitudinally down the control line (22) by a longitudinally arranged outlet (35) so that substantially all of the fluid is directed to backfill the control line. The system may be embodied in a block arrangement in which bores are drilled in a block housing and in which the branch conduit (19, 25) is formed by passages drilled in the block or may be formed from discrete hose sections and couplings.
