67 Valiant: brake problems. need help

I got a 67 Valiant /6 3sp. It has all drum. I bought the car a few months back and I'm trying to make it road worthy. I bought new brake shoes and drums for it. I replace the rear wheel cylinders, but the front ones I was having problems removing them, so I took the hardware out of the front wheel cylinders, cleaned out the clyders and replaced the hardware. The master clyinder, I unbolted the mounting bolts from the firewall then I was having problems removing the linkiage bar that goes to the brake pedal, I looked under the dashboard I wasn't able to remove the brake pedal ( with the master clyinder mounted or dismounted.) So, I cleaned up the master clydier, bolted it up the firewall, filled it up and put the cover back on. I raise the back end of the car (since there is no room to get to the bleeder vavle) and started bleeding the brakes. The master clyinder is on the driver side, so i started on the right rear tire. This is were things started going wrong. The brake line that goes to the right rear tire was a little lose and there was some brake fuild comming out, using a 3/8 line wrench I tighted the line, but as soon as I took off the line wrench, the brake line move back where it started. I notice the is bracket holding the brake line on the rear axle, but where the brake line hoops is no where near the bracket, so I used zip ties to hold it down ( I was trying to gentenly forming the line to have stright path vs a hoop)as I tighted it down. I had a friend hold the brake pedal all the way down as I open the bleeder vavle. I tighted the vavle, the brakes were pumped, no fulid came out. I repeated the process 3 more times and I move to the diver rear tire. I didnt have a problem with the rest of the wheels, but the brake pedal was hard when I first bought the car and now it would go 3/4 down til there was persure. I torqued all the wheels lowered the car and decided to test the brakes. My driveway has a decent degrade, my car backed up all the way down the hill, towards the end of the hill I had to cut left in order not to hit parked car. I put the car in first gave it some gas got it moving to 5 mph and tried the parking brake, it worked. I drove to the end of the street while I kept it in first. The brakes didn't worked, unless I pumped them or used the parking brake. I parked the car went to bed since it was 4 am. I'm new messing around with cars, and the only experince I got with doing brakes are on my ram, which has touchy brakes ( thats how I like it). I was wondering if anyone out here has gone thru this before, or has an idea of what could be wrong. My only guess is the master clyinder and/or the brake line that hoops.
