If the reservoir is going low,that fluid has to be going somewhere.I'd take the dust boots off the rear cylinders and see if they are leaking.If they are and it gets on the drum(s) then for sure the rears will grab etc. as I'm sure you know,and I'm sure you already checked this!
Other than that,double check that the drums and shoes are immaculately clean and adjusted right up until they drag a little.And re-bleed the MC.
Personally,I am going to an adjustable Prop valve simply because of the different loads I carry.But you DEFinately need to find where that fluid is going.
