having a fluid pressure regulator responsive to a speed condition

Full Title

Arrangements for adjusting wheel-braking force to meet varying vehicular or ground-surface conditions, e.g. limiting or varying distribution of braking force (by changing number of effective brake cylinders in power brake systems B60T17/10) > responsive to a speed condition, e.g. acceleration or deceleration ( ; B60T8/28 takes precedence; electric devices on electrically propelled vehicles indicating the wheel slip B60L3/10; measuring linear or angular speed per se G01P3/00) > having a fluid pressure regulator responsive to a speed condition
