    So, i did a brake drum to disk conversion the other day and now i cant get my rear brake fluid into the calipers. i have a new Master Cylinder that was bench bled properly a while back, the proportioning valve has fluid going to it, the ABS pump has fluid going to it, so all three components have positive fluid. i tried pumping the brakes, gravity feed and even purchased a pump to suck it through and nothing. I unhooked the T-Block where the single brake line goes from the front to the rear and then T's off to both rear ends and not a single drop of fluid was present.
    Now, when you do a brake conversion you have to eliminate the ABS sensors from the rear end so i am thinking that when i disconnected the ABS lines and THEN took out the fuses and buses in the electrical box so the ABS light would not show on the instrument petal that this might be the culprit???? Does the ABS pump have to be on to bleed the rear brakes and if so i guess i have to leave the electrical buses and fuses in the panel?
    I get great flow to the front calipers so i am scratching my head on this one. Is it possible that the ABS pump without the fuses and buses is causing the lack of flow on the rear brakes?

    okay, figured it out. The ABS shut down when i pulled the fuses and buses out. popped them back in and fluid finally started flowing. now im having problems with the left rear grabbing and smoking. Is this due to air still in the system or is the new caliper not functioning like it should? It all seemed to work perfect when i first took it down the drive and made abrupt stop but then it started with this problem.

    Air would make things squishy, I would think, not make it grab. (note...I am pretty sure that is the first time I have ever written "squishy" in a post.)

    I would still double check on bleeding that side just because... Check on the rest while you are there.

    Update. Ended up having a collapsed brake line from abs to rear. Problem solved. Amazing how much I over thought the problem and didn't go with basic issues first. Just couldn't imagine a hard line brake line could collapse so didn't go there. Thanks for the suggestions.
