#1 3.8 pedal box query

If a 3.8 pedal box has two rear master cylinders on it what is the outcome , or two front cylinders for that mater ,
My symptom is holding on of the front brake , no matter how much I adjust the adjustable push rod , which is going into the rear ( top ) master cylinder ?
Thanks in advance

If what you are referring to is the different lengths of the internal piston on the original masters then the brakes should still work even without this. New masters contain pistons of the same length.
So I doubt that this is the cause of your front brakes sticking on. I would be looking at the calipers and the flexible hose, and making sure that the pedal box is assembled correctly and that nothing is jamming it.

If you want to know more about the respective behaviours of the front and rear master-cylinders, this thread tried to work out what goes on in there.

It's worth reading just to explode some of the cod-science that has grown up around them.
In fact, please go and read it as I've just wasted half an hour restoring all the photo links.
