Default No Fluid to Rear Brakes?!

Here is the deal. I have seen similar posts on here and other places that got close to what I need, but nothing exact.

I bought my Ranger in October and have been driving it. The ABS and Brake lights came on so I checked the fluid level and it was low. This happened 2 more times so I pulled the tires off one at a time and found the problem.

The line leading to the driver side rear brake was snapped and leaking fluid so I repaired it, checked the other tires, and changed the shoes (front pads were good). When we went to bleed the brakes, NO FLUID WOULD COME TO THE BACK BRAKE LINES. We pumped and bled over and over again.

There was fluid being sent there before because it was leaking fluid.

Some solutions I have found are replace/clean proportional valve, replace/clean ABS valve, gravity bleed overnight, bleed the front brakes to open the valve for fluid to go to the back.

Any suggestions are useful. If it does happen to be the proportional valve or the rear line distribution (or ABS valve), where is it located.

While doing the brake work, I had the help of my grandfather who owned a brake shop for 25 years. He said he had similar issues before but a long time ago when it was an equillizer valve. He doesn't think they use them anymore.

Thanks Guys

You try bleeding your master cylinder? Work your way back and bleeding at every connection.

I think so. When you say bleed the Master Cylinder do you mean this: press the brake, open the bleeder valve, close the valve, and let go of the brake (with a partner); in that order. That is what we were doing. I have tried bleeding closest to farthest and farthest to closest. No dice. What I am doing now is what my friend calls "gravity bleeding." The Master Cylinder cap is off and I have the brake pedal pressed with a pole. The two bleeder valves in the rear are slightly open. I'm going to check on it in a few to see if the fluid level has changed.

Thanks for the reply.

Bleeding the master is having someone pressing the brake and loosening the brake line fittings on the mastercylinder itself. Have you pulled the Master Cylinder and checked the seals?

Have not done that. I wouldn't suspect that would be the problem since the front brakes are still receiving fluid and the rear brakes were receiving fluid prior to the repair and shoe change, since I was loosing fluid and there was fluid all over the tire. The master cylinder is good, I'm sure of. I suspect there is alot of air in the line since there was a broken line. Plus, I still have pressure in the brake pedal, there is no loss in Hydraulic pressure. If there was a major broken seal, the brake pedal would hit the floor. I can still drive but no back brakes
