Adjusting brake drums to eliminate pull

So, recently my car has developed an extreme hard pull to the right when braking. I'm still on the large front drums for the road runner.
(that's on the upgrade list for next year, discs)
So I noticed that the strut rod bushings were shot and removed the torsion bars and installed new Moog problem solver upgrades today. Same issue.
So now i am back to looking at the brake adjustment or possible brake hoses.
Oh, BTW- after the immmediate hard pull to the right it tends to straighten up.
Rest of the suspension is tight.

Ideas?

A pull to the right means the left side ain't doing its job (for whatever reason). open it up & see what's up.

Maybe it makes contact before the other side.sticking parts.

Make sure you have the pads in the right orientation.

Check the brake drum backing plates for wear where the brake pad frames ride. I recently had to weld and smooth the rear backing plates out on my pickup rear brakes to get the pads to move and return smoothly. They can fall into the groves which makes the brakes feel inconsistent and touchy.

Another time I had pads that were glued instead of riveted and the leading edge came unglued from the steel frame. When the brakes came on the loose part of the pad would grab the drum and bunch up which would cause that one brake to apply way too fast. Once that partially unglued pad was swapped out all was good again.

Old backing plates can get notches worn into them where the brake shoes sit against them. The shoes stick in them. I've welded them up and dressed them off with a grinder.

Are you using the stock self adjusters still? If so remove both drum and see if one side is looser or tighter than the other on the adjusters
Correct as needed

Could be a bad wheel cylinder not working on the opposite side of pull

there is some good suggestions here. Adjustment/tightness on one side or the other will not cause pull. When one side starts to touch, fluid flow will go to the other side and push on that side until it touches. That is the neat thing about hydraulic brakes, equal pressure on both sides.

aligned the car today. adjusted front brakes evenly. let front rear shoe is coming unbonded.
wheel cylinders move freely on both sides.
Brakes hoses are dry rotted on both sides.
these are factory drum brakes with probably all original parts except wheel cylinders.
car is a 69 road runner with a new 440/505 kit , S60 Dr. Diff Dana w/4:10 gears. 4*speed.
Can someone look at this part number from Mancini Racing and let me know if it will stop the car good? If I'm gnna convert to fron disc, I want to make sure this kit will get the job done!
BTW- Manual brakes,too

Believe it or not, theres a lot of 50 year old cars driving around with original brake hoses. Last year I had my rear brakes starting to drag, replaced both rear wheel cylinders , both were filled with crud. Resembled , the problem was worse. It was the rear hose . The line acted like a check valve, a lot of hydraulic brake going in ,nothing coming back. I bet it's your rubber hose.

i replaced the rear hoses when I did the S60 Dana upgrade

I would get the drum setup straightened out first. I would replace the bad/unbonded shoe (if I am reading that right) then spoon em up tight then back off the other way till free & you hear a slight "tick" of contact at one point in the tires' revolution as you spin the wheel(s) forward by hand.

But did you replace the front ones also at that time or do you know if they have been ever replaced?

Got the same exact problem with my 68 RT Charger, only it pulls left.
just bought two wheel cyls and new hoses from rock auto.

Pretty sure factory lines and wheel cylinders are still on the car.

front hoses are original,

There is s good chance that if brake lining is not replaced pull will still exist if ever contaminated. . Once lining has been soaked with grease or brake fluid, it is likely you will be unable to clean throughly. Such compromised lining can/will often cause a severe pulling,,,,drums too must be throughly cleaned with carb or some such cleaner.

Be very careful when installing shoes and other components, so as greasy hands do not re-contaminate surfaces.

I learned a very long time ago not to blow compressed air to clean brakes after pulling drums. Vacuuming is advisable to start with for lung safety and not causing a general mess of your environment. Finish up with air but wear a nose mask and eye protection.

Not as critical as when asbestos was standard lining material, advisable nonetheless.

t's a brake hose!
finally gonna upgrade to a front disc setup.
I see mancini racing sells a kit made by MBM. Anyone use or heard of them?

I would call Dr. Diff, he is a member here and will look after you.

Thanks for the advice, i just ordered my kit from Dr. Diff.
Incidentally, that's where i bought my S-60 Dana as well as my driveshaft from.
What a great guy to deal with, a real pro at customer service (answers the phone, patient with my stupid questions, HONEST) a real asset to the hobby.
I shopped it around and there are cheaper kits out there, and he did not dog any of them, simply explained the differences. If anyone is looking for a disc brake upgrade, don't waste your time looking around; I already did the homework.

FYI, if anyone is curious about weight of complete 11 inch brake conversion kit
VS complete stock drum brakes-
Stock size disc kit unboxed weighs 98.5 lbs including calipers, pads,
Rotors, hoses, backing plates, spindles, brackets, bearings, and all
Hardware.

I will weigh the complete drum setup after removal and post results

This is the stage 1 kit from Dr. Diff

thank you, weight savings is always important.

BTW- I am offering up the old stock drum setup complete in the free section,
for any purists, or if you just need parts. Just pay the actual shipping

Well, yesterday I finished the disc brake upgrade. The only hicccup was having to remove the welded on sway bar tabs on the lower control arms to allow front hanging of the calipers.
Total weight of factory front drum brakes: 96.6 lbs.
Total weight of disc brake upgrade: 98.5 lbs.

Where's the face palm smiley?
