Abstract
A brake system comprises an electronic stability control (ESC) module defining a first interconnect passage, and a pressure supply unit (PSU) module defining a second interconnect passage in fluid communication with the first interconnect passage. The ESC module includes a first pump configured to transfer brake fluid from the PSU module and to a plurality of wheel brakes, and a prime valve configured to selectively control fluid communication between the first interconnect passage and an inlet of the first pump. The PSU module includes a second pump configured to transfer the brake fluid from a fluid reservoir to the first interconnect passage, and a bypass fluid passage from the fluid reservoir to the ESC module with an inline check valve allowing fluid flow through the bypass fluid passage from the fluid reservoir and to the ESC module while blocking fluid flow in an opposite direction.
