Crane Innovation in
Brake Control –
Technology Evolution
Mk1 Crane introduces first antiskid in 1947
Electronics to drive rate sensing &
Mk2 First wheel speed transducer linear four-way pressure control valves
Mk3 First adaptive control
Higher response hydraulic control
valves; Improved brake control,
smoothness and efficiency
Mk4 First microprocessor based
digital system
Improved control algorithms;
efficiencies >95% ; Unigain antiskid
valve; Improved system performance
under variable pilot pedal input
Complete brake-by-wire

Mk5
system
Very high performance digital brake
control; used on B787 (electric brake)
Program Overview
• USAF Wheel and Brake System Improvement – “WBSI”
• Reliability and performance improvement program
Major Components of System Upgrade
• 3000 psi Brake Metering Valve (Eaton)
• Mark IV Antiskid Brake Control System (Crane)
• Wheels and Carbon Brakes (Goodrich)
Hydro-Aire, a Crane Aerospace brand, is the legacy supplier of all
C-130 brake control systems

USAF
Antiskid Upgrade
Drivers
• Mark II brake control system on USAF C-130 E/H
– Limitations
• Older analog technology with obsolete components
• Low braking efficiency by today’s standards
• Control limitations prevent efficient control of carbon
brakes to allow inherent operational and life
improvement characteristics
• Similar J model antiskid configuration and
performance characteristics
• Provides Fault Isolation

Mark IV
System Upgrade
• Provides Digital Brake Control
– Velocity Control / High Efficiency braking
• Proven Technology
– Military: C-130J, C-17
– Civil: 737, 747, 757, 767, 777, 717, most
business and regional jets
• Fully Compatible with new Wheel and Carbon
Brake
– Enables maximum braking performance

Mark IV Benefits
Performance
• Improved Brake Control Efficiency
Under varying weather and runway conditions,
ability to stop at shortest possible distance,
without encountering brake lock and uncontrollable skids.
• More control leads to:
• increased performance
• improved safety
18
Mark IV Benefits
Costs
• Reduced Operating Costs
– Digital components, eliminates analog parts obsolescence
• Commonality across USAF fleet
– Extends brake and tire life by reducing “hard skids”
• Inherit benefit to the improved braking efficiency
performance
• Reduced Maintenance Costs
19
– Added Fault Isolation Capability – Fault Display Unit
• Reduces troubleshooting and maintenance actions
• Reduces spares inventory
• Eliminates need for field level tester
Mark IV Benefits
Fault Isolation
White “flag” indicates component fault.

Mark IV Benefits
Reduced Troubleshooting and Maintenance actions
 Mark II:
 Perform Press Test – Cockpit
 Locate Fault:
 Wheels – Pull each Hubcap
& check transducers
 Antiskid Control Unit Access Hog Trough
 Check Brake Control Valves
– Pull panels
 Replace faulty part(s)
21

Mark IV:
Visually check FDU
 Go directly to source of
fault(s)
Replace faulty part(s)
