P-38 Wheel Brakes Weakened Recently

[-332FG-brooklynspo]

I have noticed the wheel brakes in the P-38 and A-20 were weakened at some point recently. I can say this with confidence as I fly these two planes regularly with my squadron. (There may be other planes whose brake modelling has changed but I would not be able to notice the changes, based on memory.) 

One result of the changes is that both planes can no longer perform engine run-ups as they could previously - the brakes will not hold the plane.

 

The AAF P-38 pilot's training manual indicates the brakes should be able to hold the plane at up to 54" manifold and 3,000 RPM. This is not the case with recent changes.
 

I have not yet found any documentation about the A-20's braking power.
