I just recently replaced read high pressure line to the rear and now have no compression. bleed brakes on all four tires yet still no compression.
-Double check. No leaking....?
-If not leaking. When you bleed it. you might need some one to help you pump the brake.
-Make sure Pump the brake (Hole down still)/Now open or release the fluid and Closed BEFORE release the brake pedal. Repeat this until no bubble. And make sure the fluid reservoir never empty to Bottom.
You should be good to go.

if you look on the inside of the wheel you will see what looks like greese fittings you need to have somebody pump and hold the brakies and then you need to slowly crack it open by unscrewing it untill you get air then wait till it stops t5hen tighten it and pump the brakes again and do this again dont let the brake fluid run out of the resivore ok pretty soon you will feel the brake pedle start to get hard then do this a couple of more times and then you will be done ok best regardss mike

Sounds like the proportioning valve is stuck. You may need to break a front bleeder loose and hit the pedal the unseat the valve. Then blead the rearbrakse and then bleed the wheel where you broke the bleeder loose. That should work.
Good Luck

Why were the brake lines replaced?
Sounds like the mastercylinder may have run dry. You have to bench bleed the master and then DO NOT allow fluid to run low, while bleeding brakes...
if master cylinder runs low on fluid and air gets in, almost impossible to bleed with out releasing the lines and bleed master it self.
