Hydraulic Brake System: Description

WARNING: This page is about a different car, the 2003 Buick Regal, 2003 Buick Century, 2002 Buick Regal, and 2002 Buick Century. However, it is still accessible from the selected car via links, so may be relevant.

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 2 hydraulic circuits, supplying diagonally-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 Dynamic Rear Proportioning (DRP), which is a function of the ABS modulator. See DESCRIPTION & OPERATION in appropriate ANTI-LOCK BRAKE SYSTEM article for specific information on the operation of DRP.
  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.
