Unusual 66 Brake problem

[stang7606]

I have a 66 coupe I restored about 10 years ago. It has 4 wheel drum brakes with no booster. When I took the car out for the first time the left from brake was locking up with very little pedal pressure, throwing me into oncoming traffic. I then replaced both of the front wheel cylinders, thinking there was an issue with one of them. I also checked the rest of the brakes for any abnormalites and everything seemed fine. The pads all had plenty of shoe. After I finished all of this, the car acts VERY funny. For aproximately the first 2 miles of driving, it now pulls severely to the right (front right wheel locking up) when the brakes are applied. After those 2 miles, the car will stop straight, but does not stop very well. If you let the car sit for a few minutes, it goes back to pulling to the right again.

Sorry for the length, but does anyone have ANY idea where I should go next? I see no kinks in the line or anything. Thank in advance for any help.

Sounds like a simple adjustment issue. Check your manual for adjustment proceedure. Also, I put a skim coat of anti-seize lubricant on the brake pad to backplate contact points.

What I found on my '66 was if the right front was locking up to soon, there was a problem with the opposite side. I found the shoes were not moving freely even after a complete rebuild. Cleaned and a bit of lube on the contact points as mentioned and they work great.

thanks, I will try the antisieze. I know the are adjusted up properly, but may just not be working correctly

Just to go out on a limb here, but could you have a brake line problem. Something either in the line or a failed line. If a rubber line fails on the inside parts of rubber can bind up the system, in effect not allowing the retraction of the shoes. Did it bleed normal, as in did you get about the same amount of fluid out each side when you released pressure?
