Who told you this? Did you or he stop and think for a minute that hundreds of thousands of cars were built during this period as there were no disc brakes in 1962, and yet these cars did not have grabby brakes?

Have you you checked the service manual? There is a Diagnosis section in the Brakes section with possible reasons for grabby brakes. It's shown below. You say you "put new brakes on." That's not very informative. What parts, exactly, did you replace? Presumably your "new brakes" included new brake shoes, so we can rule out both B and C on the list as you say the drums have been turned. But there are other possibilities, some of which don't involve components at the wheel at all but rather involve the power brake unit.

Remember that it IS possible to make your brakes work correctly short of replacing them with discs. If it was your mechanic who told you that the only solution is discs, find another mechanic. If it was your brother-in-law, find another brother-in-law.

There is some way to fix this problem. When new this car did not do that, something is probably just adjusted wrong. Take apart and look .

I am guessing you are getting more stopping power than you expect for the amount of force applied to the brake pedal. If this is correct, I recommend looking at the master cylinder or the vacuum booster, if the vehicle has power brakes. One of my cars had a failing vacuum booster and a symptom was the brakes seemed extremely sensitive, so that pressing the pedal lightly resulted in almost total brake lockup. After replacing the vacuum booster, the brakes worked correctly.

As already stated, you should be able to remedy this issue without installing disc brakes up front.

For me it was always the self adjusters ratching tighter and tighter ever time i backed up. I took off that part of the hardware and adjust them myself once a year. For the most part i have found them unnecessary.

Self adjusters are pretty reliable when the parts are good and setup correctly.

Without being there it's difficult to say. It sounds to me like the brakes are just adjusted too tight. There is an adjustment wheel between the two pads. Try loosening them a few notches and see what that does for it. It may be too who ever turned the drums left the surface too rough.

Who ever told you disc brakes is the only fix I wouldn't listen to them anymore. Complete idiot.
