When comming to a stop in my '66 F100 352 cruisomatic. I get a sharp or gentle pull to the right, depending on the amount of braking force applied, and even at that it tends to be somewhat intermintent... though usually remains a problem.
Could this be due to a clogged brake line? or would it be something else. I havent begun to check into it. Just looking for thoughts on the problem.

Randy, Start by checking the inside of your rear wheels and tires for a wet look. Leaking brake fluid or axle oil will cause this action. The next thing to check is the brake shoes on the rear wheels and then the front. Might be a great time to upgrade to power disc brakes with a I-beam upgrade.

In the cool still quiet of night, you can hear chevies rusting away.
Sounds like it's in the front to me. My guess is that the left side is out of adjustment. Pull the front drums off and make sure you don't have a wheel cylinder leaking. Take a look at all of the hardware to see if it's in good condition and then adjust the brake shoes out. You may want to pull the adjusters off, clean them up and lube the moving parts with white lithium grease. When time and budget allows think about the disc upgrade that John mentioned. It makes a huge difference in the way your truck drives and it's safer too. It can be done in a weekend.
I had the same problem with my 66. I did everything to try and remedy the problem. The brakes kept going out of adjustment. finally found that I had a emergency brake cable that had frozen in it's tube. I replaced it and have not had a problem since.
'65-'79 front suspensions interchage. The brake booster/master cyl. will bolt right to your firewall. Very little modification to do this swap. You can get the parts at the junk yard and auto parts store. If you decide to do it and need some advice feel free to e-mail me. It may be in the tech articles on this site.
Easy way is to swap the entire I-beam/brake assembly intact, providing it is not totally worn out. It avoids playing with the king pins! I'm still running the stock brakes on my '66, just kind of used to them, I guess!
Thanks for the comments everyone. I have found the tech article on the upgrade. Now I just got to fund and find the parts. Alas that will be the easy part I hope Then getting the time to do the upgrade will be another chore. Well I know that I can ask for advice when needed. Again thanks.
Randy, There are two ways of doing the upgrade, and I think the easiest is to swap out the complete I-beams. I also recommend buying your donor truck and keeping it until you have put everything on your truck. I changed not only the discs, but the power steering, auto tranny, and soon will swap in a tilt wheel.

If you find that the wheel cylinders are not stuck or leaking, and the adjusters are working properly, you may need to modify your driving habits.
Self adjusting brakes are common on almost all vehicles since the mid fifties. But in order for them to work, you must drive in reverse regularly!!
I don't mean that you have to drive around the block in reverse, but rather when you back out of the driveway or parking space, make sure to apply the brakes FIRMLY in order for the adjusters to what they were designied for.
When I purchase a used vehicle, I usually make it a point to do a few reverse stops to adjust the brakes. Usually this firms up the pedal quite a bit.
When the drum brakes gets worn, it means that the back plate also get worn. You would see the worn spots if you remove the brake shoes. The shoes moves back and forth and leaves grooves in the back plate, and this often cause the brakes to brake uneven.
The solution is to remove the back plates and weld in the grooves to fill them up, and then use a grinder to make the surface flat like it was as new.
Then reinstall the back plate, and the rest of the parts... of course with new parts if neccessary.
Also, use some high temp. grease on the adjusting screws, Omega 99 or something like that.
