System Component Description
The hydraulic brake system consists of the following:
Hydraulic Brake Master Cylinder Reservoir: Contains a 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 two hydraulic circuits to the Brake Modulator Assembly.
Under normal braking the Brake Modulator Assembly allows fluid pressure to be distributed
through out the hydraulic brake system.
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
Electronic Brake Differential (EBD), which is a function of the ABS modulator. For
specific information on the operation of Electronic Brake Differential (EBD) refer
to
ABS Description and Operation.
Hydraulic Brake Pipes and Flexible Brake Hoses: Carries brake
fluid to and from hydraulic brake system components.
Hydraulic Brake Wheel Apply Components: Converts hydraulic input
pressure into mechanical output force.
System Operation
Mechanical force is converted into hydraulic pressure by the master cylinder,
regulated to meet braking system demands by the pressure balance control system and
delivered to the hydraulic brake wheel circuits by the pipes and flexible hoses. The
wheel apply components then convert the hydraulic pressure back into mechanical force
which presses brake linings against rotating brake system components.
