on a stock master cylinder which one will develope more preaure and volume front or rear master cylinder?
I am going to run an adjustable bias nob and want it on the line going to the rear brakes. should i connect it to the front or rear outlet for the master cylinder.

i am considering connecting both outlets into one line then reducing it on its way to the back brakes. will this be the best way

Both ports on the mastercylinder will make the same pressure. What do you have for brakes? On the stock system with calipers on the front and drums on the rear the large resivor is for the fronts. DO NOT connect both lines together. There is a reason that all auto makers went from a single line master cylinder to a two line unit. If you plum the front and rear together into one line and you rip a brake hose you will have NO brakes. keep the front and rear seperated. That way if you loose a brake hose, you will still have brakes on half of the car.

I HAVE DRUMS ON THE REAR. AM I RIGHT THAT DRUM BRAKES WILL TAKE LESS VOLUME THAN DISK BRAKES? AM I ALSO RIGHT THAT REAR DRUMS NEED LESS PREASURE THAN FRONT DISKS?

Drum brakes require more volume to operate because the spring on the shoes pull them all the way against the stops on the drums. If they are not adjusted correctly, they will take even more volume.

??? what takes more volume a hole that is 2" in diameter or 1" come on use your brain man disc take more volume anyday of the week

disc also take more pressure because of clamping pressure as apposed to drums which self energize (you know the brakes are hinged in 1 pin either top or bottom depending on application) with the hinge point the brakes wrap them self up in the drum creating more power(not as much as disc)

not sure about more presure but deffinently more volume going to the front and it shows in the line size that is run to it.
