Hydraulic E-brake set up

I was curious, I'm planning on running the RS with the hydraulic e-brake set up, however Subaru runs two lines to the back of the car. Will I lose braking force if I "T" it into a single 3/16" line just before the ebrake and then back to two lines just after the ebrake? Does the amount of line that I "T" into a single line have a large effect on the pressure or could it be T'ed by the firewall and just one line run to the ebrake?

Thanks

 

Well, this or something like it is really the right way to go. It keeps the dual-diagonal braking intact.

 

I was considering this as well, but for the money... I'd rather use what I have.

 

I am curious as to your reasons for why you want to convert to a hydraulic "e-brake".

It looks like you are wanting to convert it to using your stock calipers as part of your "e-brake" correct, and what would you be using as your e-brake handle?

 

Well. The ebrake cables in my car are missing. Also the brake lines are missing. They also included the hydraulic ebrake with the car when I bought it. I think it will be a lot of fun. I've never used a hydraulic one before.
