    i think it makes the baking much better for the price of an oil change and the master you cant go wrong - im wondering is running a bigger booster better also

    think was i put the 32 master in with the 86 booster n 86 rubber on the master and when i went to bleed the brake they were soft as, so i took them off and going to bleed the brakes again.

    so its recommended to have the r32 master with the s13 brakes?

    if its just the standard s13 single piston stuff then no, its kinda pointless.

    Some Nissan master cylinders have the rear proportioning valve in it (the type that has R on the front port and F on the other 2). In theory, you won't want to use the Toyota proportioning valve at the same time, as that would limit rear brake pressure too much.

    Some R31 masters are 1", some R32 masters are 15/16" and some are 7/8", and they all look the same. And there are many other types also...

    When ever you change to different front brakes, try and measure the piston diameter. Even if you can't use the info, someone else could. And it would make it a lot easier in determining what size master would be good.

    I am using the R and F type 2 port version.. With stock brake bias it seems to work really well.. I run front hulix 4 pistons and rears are r31.. I recommend it as braking is of most importance when spirited driving

    yeah but you are using 4 spots.... for sure the pgrade is a great idea on 4 spots.

    on single piston slides it is not necessary. There is a reason why the s13 needs an upgrade when it goes to 4 spot conversions. it doesnt push enough.

    If you have a mastercylinder that is too big you wll loose any pedal feel and modulation and just have fucking on and nothing at all...

    The good thing is, that you mentioned it's a 15/16". Now tell me the diameter of your brake pistons and I can work everything out.

    Otherwise it's just taking peoples word for what feels OK.
