Little Brake Issue...

Need some help, does anyone have some in site why the following is happening.
Did a brake conversion on my 70 cst drum in the back disk in the front.
1.Changed out the master cylinder (old one was rusted, didn't want to take any chances.) installed a new proportional valve designed for disk/drums.
Went to bleed this morning, back brakes no problem. Bleed with no issues, front brakes not so much.
Cannot get fluid to the calipers, tried performing a vac bleed, old fashioned bleed, nothing. Its not my proportional valve, checked that, interesting fact I can disconnect the steel line from the hose going to the calipers, and get fluid, I verified the rubber hoses, and bolts going into the calipers.
None of this is making any sense,

Does anyone have any suggestions?
Thanks

Re: Little Brake Issue...

It looks like the calipers are reversed sides. The bleeder should be on top.

George, GEEEZE I evan read that on-line, and looked right past the obvious. You are 100% correct, I've spent the whole day looking for the other issues, that I completely ignored the position of the bleeders... Thanks for pointing that out to me..

Re: Little Brake Issue...

I was just gonna suggest that. Went through the same thing recently on a ‘67 cougar restoration Bought a front disc kit that utilized ‘94 S10 calipers. They mounted on front of the adapter brackets putting them in front of the rotor
The calipers had and R stamped on one and L on the other. So of course the R goes on right and L on left.
Problem was on a S10 they are mounted back side of rotor so opposite for this application.
I pulled my hair our for 2 days then re read the directions carefully. Bleeder up.

Good thing that the one picture showed the caliper with the bleeder pointed down.
