Hi folks, I have 69 RR, drum brakes all around, all shoes, drums, hardware in excellent shape.
When braking, I get a slight pull to the left....So I proceeded to bleed entire system, didn't find any air...spun up the adjuster on right side a bit to maybe "even out front braking"...nothing changed. Possible bad wheel cylinder? Looking for help, thanks!
 
Clean all the drums with brake clean and the shoes, maybe sand the shoes with 220 grit just enough to give them a new surface. How old are the cylinders? Most likely it would be a surface condition.
 
You might make sure the wheel cylinders are correct as well.
Maybe try a side to side swap see if it follows?
All front end components tight?
Are you sure a rear is not dragging on you?
 
Assume you know, even the rear brakes can make it pull to one side. Unless something is going on with parts, a careful adjustment on all four, same adjustment, should straighten it out.
 
yep...checked all those items....the more I think about it, maybe have to go back and adjust up the opposite side again, I'm thinking I didnt go for enough, If I remember correctly, turn adjusters up to lock up wheel, then back off for a slight drag?

No.

My old age is oozing out again. Yes, tighten the adjusters until the wheel is locked...then, counting each 'click', back off until the wheel freely turns by hand. Use that number of 'clicks' to adjust the other brakes, tighten down, then back off the same number of clicks.
That will make all your brakes even, and should stop straight.
 
I suspect the right front wheel cylinder is hanging a bit. Dot 3 brake fluid is not nice stuff, it absorbs moisture.
I flush my cars out with synthetic and use that instead.
 
I have the same problem with my '69 Road Runner. It seems to stop straight when cold, but the longer I drive it, the more it seems to pull. Readjusting is getting old.

Drum surface needs to be near equal, also. Mine would pull slightly right when cold and slightly left when hot. Rather than invest in new drums and parts, I did the Dr Diff disc kit and have been happy since.
 
I had considered that. The drum surface looks the same and smooth on both side, but maybe I'll have them resurfaced. I suppose they could be glazed.
 
Shoes could be glazed. Quick fix, rub 'em down with sand paper.
Might also matter what brake fluid your using. Too many types these days.

I thought me using good old fashion DOT 3 was correct?
 
DOT3 is fine. It's cheap, do flush and bleed if you suspect an issue.

Dr Diff sells a b body front disc conversion kit. It's based on 77 aspen volare brakes. Nice upgrade in my opinion.

DOT 3 is fine and what a majority of folks use. It absorbs moisture, and always has, so it is a good idea to flush once in a while. Also, it will remove paint so wipe any spills immediately.
