Rear brakes wont work.

[Jamesconn]

I have converted my s13 rear brakes to R33 GTR Brembo's, it already had a R33 servo and s15 master cylinder, we also fitted hydro with girling .625 brake cyclinder and Driftworks braided lines ( fitted right way, front of cyclinder to rear etc) we have run through about 3 liters of brake fluid over a week bleeding, front brakes (R33) are great, no leaks anywhere, cable handbrake is locking wheels no problem, but i have nothing at rear, when car is jacked up i can run through all the gears with the brakes fully pressed on, the rear hydro line was a bit long so its lying in a 8 inch loop under the rear carpet, would this be the problem?, if not any ideas, ( the pistons are not seized either), cheers..

Are your calipers the right way around, throw up a pic or two off your set up, if your brake nipples are pointing down then there the wrong way around, is there fluid coming from the nipples when bleeding
