Component Description

The hydraulic brake system consists of the following:

  1. Hydraulic Brake Master Cylinder Fluid Reservoir  - Contains supply of brake fluid for the hydraulic brake system.
  2. Hydraulic Brake Master Cylinder  - Converts mechanical input force into hydraulic output pressure. Hydraulic output pressure is distributed from the master cylinder through two hydraulic circuits, supplying front-rear opposed wheel apply circuits.
  3. Hydraulic Brake Pressure Balance Control System  - Regulates brake fluid pressure delivered to hydraulic brake wheel circuits, in order to control the distribution of braking force. Pressure balance control is achieved through a combination valve.
  4. Hydraulic Brake Pipes And Flexible Brake Hoses  - Carries brake fluid to and from hydraulic brake system components.
  5. Hydraulic Brake Wheel Apply Components  - Converts hydraulic input pressure into mechanical output force.
