Lincoln Aviator: Power Brake Actuation / Description and Operation - Power Brake System - Overview
Electric Brake Boost
Overview
The power assisted brake system utilizes an EBB. The EBB is an integrated function of the ABS / HCU assembly and is controlled by the ABS module. The ABS/ HCU combines the functions of a conventional vacuum booster and ABS module. The ABS module controls and monitors the EBB function and sets Diagnostic Trouble Codes (DTCs) when a fault is present in the system. The IPC illuminates the red brake warning indicator and displays a message in the message center when a fault is present.
