Abstract

The four-hweeled vehicle braking system allows at least the two driving wheels to be braked simultaneously. An auxiliary unit is engaged in order to extricate the vehicle if immobile due to one of the driving wheels spinning, by restricting the braking effect solely to the wheel which is spinning. There can be a three-way valve in the hydraulic pipe between servo unit and drums. This normally allows braking fluid to flow to all four drums but it can be so set that the fluid is deliverecd to one of the brake pipes only.
