Rear brakes not bleeding right

[secondary-system]

I don't know if I posted something like this already but I'm at a compleat loss and don't have the spair cash to go to the mechanic. I replaced my old lspv with a new one you can adjust your self because my rear breaks are getting nothing but air. I replaced it because I thaught the original lspv stopped working right and thaught that would solve the problem it did for only seven pumps after That they got even worse So now I'm back to Before. So when I bleed the system my frunt breaks get nothing but fluid but the back is getting nothing but air. I see no leaks anywhere so I'm thinking the rear break cylinders are shot and some how allowing air in. When I pump the breaks I see air bubles going into the reservoir o and before I put the new positioning valve on when I bleed the original lspv I got fluid but when I bleed the rear breaks I got air.

If the brakes were bleeding correctly before you installed the prop valve and are sucking air after you installed the prop valve, the problem is with the prop valve.

the rear breaks did not work properly only the line going to the lspv was working right. then i bleed the lspv it self at the bleeder screw it bleed just fluid.

just a thought did you look into replacing the master cylinder it self i couldnt get my rear brakes to bleed because there was no pressure going to them so i replaced the master cylinder and problem solved
