Break Caliper Bolt Failure

ATTN: GT 500 OWNERS.
We recently had a customer that experienced a very costly bolt failure on the Matco brake caliper attachment. The calipers are attached to the axle stub flange using 4 ea. 10-32 full thread screws. All four bolts sheared (on one side) during braking while on a short field landing to a full stop. The plane veered into a nearby fence and the plane flipped over onto it's back. No injury to the pilot however the plane has been deemed a total loss by the insurance Co. This plane only had a few hours on it and was equipped with the Rotax 912.
I will be replacing these 10-32's with AN3-6a bolts.

This plane has enough "stuff" on the panel that he can fly at night in a snowstorm and land at a class B airport on top of a mountain.
