History1950s 1970s 2012
New UTAS-W&B Lock Ring Wheel and
Carbon Brake
August 2009 after landing at COB Speicher in Iraq, the brakes overheated on this C-130 from the Wyoming Air National Guard. Crews cool the brakes with water to prevent a fire.
History
USAF Wheel and Brake System Improvement Program (WBSI)
Overview
Lock Ring (Boltless) WheelPart Number 3-1660
Lock ring design, service proven on F-16 and C-525,000 mile wheel life
DURACARB® Carbon BrakePart Number 2-1744
Optimized 3-rotor, 6-piston design2,000 landings per overhaul
Features and Benefits
Feature Benefit
Faster tire change time 80% reduced tire change time (52 vs. 255 min. for current wheel)Decreased maintenance time
Longer wheel life 6 times longer life (25,000 vs. 4,220 mile life for current wheel)Fewer wheel replacements; Increased operational usage
More landings per overhaul 8 times longer life (2,000 vs. 250 LPO for current steel heatsink)Fewer brake replacements; Increased operational usage
Lighter weight 17% lighter weight (270 vs. 327 lbs. for current wheel and brake)Increased payload; Reduced fuel cost
Lower component count 17% fewer parts (490 vs. 587 for current wheel and brake)Reduced maintenance and logistics
Refurbishable heatsink Allows brake carbon re-use (2-For-1)Lower cost of ownership
New wheel and brake system reduces aircraft life cycle cost compared to current bolted wheel and steel brake.
Features and Benefits
Carbon refurbishment: Rotors & stators two-for-oneTwo Fully Worn Rotors
Machine Along Green Lines
Features and Benefits
Current steel brake hard tubing no quick disconnect
New Carbon Brake upgrade introduces flexible robust
hydraulic lines and self sealing quick disconnects
Lock-Ring (Boltless) Wheel
ReducesTire change time 80%(52 vs. 255 minutes)
EliminatesTie bolts, nuts, washers
EliminatesNon-destructive inspection of
fasteners
ReducesWheel parts count
(Just three major parts)
IncreasesWheel life 600%
(25,000 vs. 4,200 Miles)

Performance
Summary of Benefits
USAF is reviewing the need to utilize reverse props, as well as evaluating potential stopping distance improvements.
“Reduces FOD potential in the engines, especially at initial brake onset at higher A/C speeds.”
“Oil temps stay lower, engines last longer.”
“Antiskid system is very smooth without the shuddering common with the Mk II A/S system during maximum effort landings.”
Pending -1 changes remove wait time restrictions currently in the -1 for maximum, full antiskid braking effort stops.
