Ke10 Brake Query

[swiftyke10]

Hey guys, I just bought a mazda 323 master cylinder and booster from the for sale section. It was set up in a ke20 previous to me buying it. I got it home and had a look at my master to see how it would fit. When doing this i noticed the ke10 master cylinder has 3 outlets (2 front 1 rear) and the 323 master cylinder only has 2 outlets. Should i get a splitter and run the two front lines on one outlet and the rear line on the other outlet, Or will that throw out the bias?

 

Any help will be nice.

 

Thanks, Luke Swift
