Brake Problems in 84?

The problem just started this week, we put a new rear brake line on a few weeks ago because it busted when I started towing another truck so we fixed it in the parking lot of the autozone about a mile from where I bought the truck. Now suddenly whenever I push the pedal down there is nothing for about the first inch, but once I get past that, suddenly the wheels lock up, and sometimes it seems like its just the drivers side rear. I don't really mind it because it doesn't happen all the time, or at least not as bad but I have new tires and I don't wanna pay for new ones! Its not using or losing fluid, and I checked and saw no leaks underneath. What could it be? cylinder? proportioning valve? master cylinder or booster?

I had a car that did that once. It was fluid leaking around the seal on the axle.

Did you bleed the system after replacing this brake line?

Make sure all the air was out of the fluid. If you bled them, still a chance they may be some in the lines. They can take a while to bleed sometimes, and other times they are really easy to bleed.

Yeah, but it was a quick job, and all we did was that one wheel. And we hadn't had a problem til now so it didn't occur to do it again. Do we need to do the entire system or just that one wheel?

Try doing the whole system again. You said that one wheel is locking up right? That could be why its locking up...the other 3 have air in them and the brakes arent being applied as much. Letting most of the braking being done by that 1 wheel.
