Abstract
A twin-piston (e.g. tandem) master cylinder for a split braking system having disc brakes on some wheels of a vehicle and drum brakes on others has a delay valve incorporated in the master cylinder between a pressure chamber 17 and a port 32 for the supply to the disc brakes, the delay valve having a valve member 52A controlled by one 15 of the master cylinder pistons to initially shut-off the supply of fluid to the disc brakes after the piston has moved a short distance. A plunger 41 moves against a control spring 51 to re-open the supply to the disc brakes above a predetermined pressure. <IMAGE>
