Master cylinder bore size.

[turner]

We are finally allowed to run aftermarket dual master cylinders this year on our street stock.The car weights around 3200 lbs, and we are on e-mods.I have disc brakes all the way around.Just wondering what size master cylinder, and brand everyone likes?Thanks alot for any advice.

Why do you run the smaller bore to the rear?

Why do you run the smaller bore to the rear?

With the same calipers on both front and rear it gives you more rear pressure.

Thanks for the advice Jeff.I can also run the bias bar, so would you go 7/8 front and rear, or still go 1" up front?Thanks Jeff.

I have bias adjust bar and run mine with the smaller one in the rear.

Try them both ways.It's a what you like or need type of thing more than it needs to be a certain size on one end.

if you have the same size calipers all the way around you should run the same size bore front and rear, let the adjuster be just that, an adjuster.....
