Hydraulic Brake System Description and Operation

System Component Description The hydraulic brake system consists of the following:

The above graphic may not be an exact representation for every vehicle configuration. Brake Master Cylinder Fluid Reservoir (1) Contains supply of brake fluid for the hydraulic brake system. Electronic Brake Booster Control Module (2) and Brake Master Cylinder (3) The brake master cylinder and the electronic brake booster control module take the driver applied brake demand and transforms this into an amplified brake pressure. The integrated brake pressure modulator valve controls hydraulic pressure to each wheel independently and can be responsible for ABS, traction control, and stability control.

Hydraulic Brake Pipes (1) and Flexible Brake Hoses (2) Carries brake fluid to and from hydraulic brake system components. Brake Calipers (3) 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 linings against rotating brake system components.
