Right iv got a cosworth servo on my focos im bilding and i will be running it with out the ABS unit so im only running the brake pipes off the servo there are 3 ports on the servo iv been told to put the front brakes on the front port and run the rear brakes off the rear port and blank the center port off well the problem im having is im using a brake bleed kit that puts 30psi in the pipes so the front brakes bleed up in two min but nuthing coming out of the rear i even hit the foot brake but still no good so i undid the pipe on the rear port and i should of had brake fluid coming out of it at about 30psi well not a drop but when i undo the center port i get brake fluid coming out out of it . has any one done this mod befor and which ports did you use on the servo .

You need to have ignition on to bleed the rears as the pump will prime the rear pipes.
