euro spec s13 need brake help

[s13SilVia]

I have a euro spec s13 with a ca18det, I'm having a problem with my brakes. We found a leak in the steel line that goes to the rear passenger side brakes, we replaced that line with a new one, and then added a stell braided line to the caliper. bleeded the lines and everything seemed good, until I started the car up then the brake went to the floor and was real loose it did stop. I'm thinking it's either another leak some were or maybe the master cylinder is going bad need help I'm just curious if anyone would know what I should be looking for.

Thanks

did you bleed every line ? Do you have ABS ? ABS pump is hell to purge.

no abs, and we bleeded every line but 1 because the bolt was stripped. Could that be it?

Yes. You need to bleed every line.
