Lincoln Nautilus: Parking Brake and Actuation / Parking Brake - Overview. Description and Operation
Overview
The parking brake system uses 2 switch activated, ECU controlled motors to apply and release the rear brake calipers. The ABS
module controls and monitors the parking brake system and sets
Diagnostic Trouble Codes (DTCs) when a fault is present in the system.
The IPC illuminates the
parking brake warning indicator and displays a message in the message
center when a fault is present, when the parking brakes are applied and
when they are released.

Bring the engine to normal operating temperature. Connect
the Vacuum/Pressure Tester to the intake manifold. Run the engine at the
specified idle speed.
The vacuum gauge should read between 51-74 kPa (15-22 in-Hg)
depending upon the engine condition and the altitude at which the test
is conducted. Subtract 4.0193 kPa (1 in-Hg) from the specified reading
for every 304.8 m (1,00..
