I have all toy  under my sami and for whatever reason I have to pump my brakes to make them work properly put a vacume cannister back on it. I thought maybe it was the booster changed it out. Put a new master on it. Talked to a brake guy he said there shouldn't be any difference between the zuk master and the toy master I just know that my brakes suck any ideas. 

i just messed with brakes the other day, the sammie that i was working on had what sounds like the same problem that you have.  it was massive ammounts of air in the lines.  Try bleeding the lines, thats the common problem to breaks that you have to pump up.
So just do lots and lots of bleeding, and when you think theres no air in the lines...try some more, you will be suprised how much air can be in a line.
It might be somthing else, but you might as well check the simplest thing.
get some break fluid and go to do.
good luck

thanks, I'll give it a try I bought some speed bleeders to do just that just haven't got around to it. No it is noy my daily driver.
