Wedge front brakes - S cam rear?

[grendel]

So, after having a few M939A2 series... how are the Wedge front brakes on this?

I have some Axletech 4K's from an MRAP. They have air disk brakes.

Seems like a no-brainer to me.

Thoughts?

I only have a handful of miles on my truck but it stops great. There are two diaphragms on each side, so the shoes get pushed on both ends.

I can stop mine on a dime with 20k behind it without trailer brakes. Huge improvement over the m939
