1. An hydraulic anti-skid braking system for a vehicle of the four wheel type comprising a supply of brake applying fluid, a first brake on a first front wheel, a second brake on a second front wheel, first skid sensing means for sensing the behaviour of said first front wheel, second skid sensing means for sensing the behaviour of said second front wheel, a first modulator for modulating the supply of fluid from said supply to said first brake in response to a skid signal from said first skid sensing means, a second modulator for modulating the supply of fluid from said supply to said second brake in response to a skid signal from said second skid sensing means, and a valve assembly incorporating a pressure-responsive member responsive to differential pressures applied to both said first and second brakes, and said valve assembly also incorporating restrictor means operative to restrict the rate of pressure increase applied to the one of said brakes which is at a higher pressure, and means for initiating operation of said restrictor means in response to movement of said pressure-responsive member.
