No brake pressure

Hi all!

I'm running into some issues with my brakes. I do not get any brake pressure when the engine is on. I thought it might be the brake cylinder so i've changed it and bleeded the brakes with around two litres of brake fluid. Unfortunately no change, the pedal stays soft and i can push it to the floor.

I do not have ABS anymore, and i do have the brake cylinder from a Cup as my car is being used for hillclimbing.

Any ideas/recommendations?
 
I think it's worth a try to do that if you are not getting any progress,are you using a pressure bleeder?
To bleed the master cylinder you'll need to make unions for the two or four outlets you have,fill the reservoir and put all the pipes inside in the fluid,push the rod several times until no air comes out,that's the way I've done it last time,to connect it back up you'll need to be fast undoing the "bleed" unions and connect the ones on the car lol
