Well before i get going this morning i'll try on this one , There are several places to look . (1) first Bleed the brakes , (2) what shape are the brakes in ??? you could have stuck adjusters and the pistons are cocked , It could be a stuck check valve (there are two) one on top of the MCV under the fitting on the crossover line and also on the brake valve , Flow divider sticking low pump output , sticking sump check valve, that one is in the lower righ hand corner behind the MCV , and on some rare occasions the brake valve it's self. Here again it would be nice if i could see it and check it myself.
