Crane’s new digital Mark IV antiskid brake control systems are currently being
installed on the US Air Force C-130H fleet as part of the Air Force’s Wheel
Brake System Improvement (WBSI) program. The same system is also available for
foreign military operators flying legacy C-130s. The Mark IV replaces the older,
discontinued Mark II analog antiskid brake control system. Mark IV offers
improved braking efficiencies leading to shorter, more controlled stopping with
either carbon or steel brakes.
The Crane Aerospace & Electronics Mark IV Antiskid Brake Control Unit integrates
fully with the new wheel and carbon brakes, providing the same digital brake
control responsiveness and performance previously available only to the C-130J
operator. It also adds the benefits of a parking brake and visual fault display
unit to enhance operator brake control maintenance.
The Crane Mark IV Antiskid Brake upgrade includes the Mark IV Brake Control
Unit, part number 142-151; Brake Control Valve, part number 39-941; Wheel Speed
Transducer, part number 140-325; and Fault Display Unit; part number 142-15520.
