63 c10 front brakes are stuck

[jserrato714]

Went ahead yesterday and proceeded to tackle the issue at hand..I started off from scratch. Detached the master from the booster so that I could remove the booster from the firewall and measure my pedal rod length. As soon as the master cylinder was loosened my wheels could be spinned freely...Went ahead and measured the pedal rod from the firewall mounting bracket to the center of the pedal rod eye bolt..I was off by a 1/4 inch to long compared to my stock setup. I went ahead a drilled a new hole on my pedal from the center of the manual stock hole to the center of the new power brake hole which was a bit over an inch center to center.. Reinstalled all the components and sure enough it seemed to fix my problem...bleed the system following the old school two man job...Took most of the old fluid out so that it was nice and clean looking....Went for a drive and it brakes pretty good however it seemed like the pedal would need some force to brake.. so I went ahead and went back to the old stock manual hole for more sensetivy...It helped the problem..Made it easier to stop however Pedal seems to lag a bit in response and not to my liking. I have not checked or adjusted the rear drum brakes...I bleed them at first when I installed the new components and called it a day.. I am looking for that quick brake response sorta like a new car... so no more brake drag just like slow on the pedal response..What do you guys think might be the issue? Air in the lines or rear brake shoes? Feedback welcomed.. Thanks
