:hmmm: Well now we are getting somewhere I have seen this happen only a few times before. :shock: It's no wonder your having all this trouble with shoes dragging those drums were just not machined properly during their manufacture, so that after the drums are pressed on your hubs they aren't spinning in a true circle. To fix this you will need to have then turned just enough to get them round again and running true. Good luck. :nod:

I would agree with however I have had 3 sets of drums on, the factory ones, ones from MACs and now a set from NAPA. They all drag in the same spot. NAPA told me they didnt need to be turned. I don't know

Yes for sure those brake shoes will eventually wear themselves into and conform matching the shape of the drums over a period of time and with more use, at that point you will then have your best brake operation. It all depends on how bad the problem is, if it's not draging all that bad than let it go and within that amount of time the problem will self correct. Turning the drums would just speed that all up the shoes would conform to the drums would practically be immediate. Drive it easy for awhile until everything wears into each other. Best of luck :nod:

Adjusted the front shoes out a few more clicks.

Car was pulling to passenger or driver side for no apparent reasons. Put new rubber lines on the front and that seems to have stopped it. Also made the ENTIRE braking feel better. Pedal is smooth and consistent and braking force is predictable now.

Once the shoes wear in a little more and I get the ball joints replaced I think we will be 100%

:beer: glad to hear that you are making more progress on the brakes operation. :thumbup: :nod:

Hi, on the front drums, I would not loosen the adjustment. I know the scrape, no scrape you are talking about. I would adjust the shoes tighter, as long as the wheel still spins. The same on each side. When the shoes are adjusted up the pedal has very little travel.
Then drive it and if it feels good, leave it.
I have been known to bleed the brakes again, a week or so later, after using the car and guess what, you get a little more air that worked it's way through the system.
So if the brakes seem good after another adjustment, drive it a couple of weeks, then you can jack up a wheel, check the scrape scrape sound and do a final bleed. Hopefully all will be perfect.
Good luck
B RON CO. Still workin' on it!

Did you mention if you changed the front flex hoses in all of this? I have had them deteriorate internally and create crazy unequal braking scenarios that I couldn't chase down mechanically. Fairly common when they fail to constrict inside so they act like a valve, won't let fluid through until it hits a certain pressure (delaying braking to that side when you hit the brakes), then holds onto pressure longer (dragging) when you release the brakes.
