Re: Glazed Brake Shoes Right Front Only

Ken, Is there a possible grease "leak" coming from a bearing, are the bearing seals in good condition? Other than this and what you have already tried covers my experience with drum brakes.

This ought to be interesting!

Re: Glazed Brake Shoes Right Front Only

Are both the primary and secondary shoes glazed or just one of them?

I'm thinking the shoes are dragging. Check for massive wear on the backing plate contact points. When they get sufficiently groved, the shoes doen't retract evenly. If this is your issue, a little work with a welder and grinder does the trick.

Is the self adjuster over tightening?

Make sure that the hose hasnt collapsed on the inside making the brakes hold on after being applied.

Make sure that the auto-adjuster in facong the right direction in the right front. Sounds like the adjuster might be backwards in the right front, tightening the brake adjuster when you apply the brakes going forward rather than when you apply the brakes going in reverse.
Hope this helps, John.

Are '63 brakes auto adjusting? I thought they required manual adjustment. Not sure.

Re: Glazed Brake Shoes Right Front Only

Yes, '63s have self adjusters, which will adjust the brakes, if necessary, when applying the brakes while moving in reverse for base and J-65. Z06 brakes self adjust when moving forward. '63 was the first year for self-adjusting brakes on Chevrolets.

Ken:

Did you flush/blow out the junction block that splits off of your master cylinder? Did you verify that both front wheel cylinders have the same bore diameter? Did you check for any restrictions in both of your steel front brake lines? If so, then it sounds like a mechanical rather than hydraulic problem, if you are also sure that there are no leaks. It also sounds like you have eliminated drums and shoes.

If you have not done so already, make sure that both front star wheels are self adjusting type (with the finer teeth). Also, check that both sides have the spring oriented the same way, relative to the star wheel, namely, that the wide section of the spring (coil end), should be contacting the star wheel to hold it in place, and prevent "auto adjusting".
