Road safety - Hydraulic Brakes

  1. 1. Hydraulic Principles Fluids cannot be compressed Fluids can transmit Movement  Master cylinder transmits fluid to wheel cylinder. Fluids can transmit and increase force
  2. 2. Hydraulic pressure is distributed equally in all directions.Same line pressure to all wheels
