For 1990-2009 cars

### System Component Description

The hydraulic brake system consists of the following:

Hydraulic Brake Master Cylinder Fluid Reservoir: Contains the supply of brake fluid for the hydraulic brake system.
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.
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. The proportioning valve limits the outlet pressure to the rear brakes after a predetermined master cylinder pressure is reached.
Hydraulic Brake Pipes and Flexible Brake Hoses: Carry brake fluid to and from hydraulic brake system components.
Hydraulic Brake Wheel Apply Components: Convert hydraulic input pressure into mechanical output force.

### System Operation

The master cylinder converts mechanical force into hydraulic pressure. The pressure balance control system regulates the hydraulic pressure. Brake pipes and flexible hoses form the hydraulic brake wheel circuits and deliver the hydraulic pressure to the wheel apply components. The wheel apply components convert the hydraulic pressure into mechanical force which presses linings against rotating brake system components.
