So did front drum shoes and hardware also on one side did brake cylinder and flex line . So the side that’s pulling is the one I didn’t change cylinder and flex because there were ok at the time . I also adjusted equally to keep uniform braking . Still get a slight pull. Idiler arm ?
 
Your hose could have a slight blockage in it. There's A LOT of pressure applying the brakes but almost none releasing them. The slightest blockage will cause problems. When at all possible, change everything in pairs. I used to tell my customers you can buy just one sock or shoes. They both have the same wear and use. You may think about changing the rear line too.
 
Are you sure the replacement wheel cylinder has the same piston size of the original? If the replacement wheel cylinder has a different size than the original it would not apply the same pressure. Just a thought.

East Windsor? I was there today, in Riverside. Just got back home here in London.

My brakes are also pulling to the side, everything is new, I'm still working throught issues with front drums and wheel balancing.

I think it's one of my rear brakes doing the pulling, making me think the problem is in the front because I have to steer to correct it. Only happens while braking.

Also, know this:

When you have old lines, and you do brake bleeding, you push new fluid through the lines, stuff will break away from the inner surface of the old flex lines and plug up the system, and can act line one-way valves - allowing fluid to flow toward the brakes but prevent it from coming back, leaving the brakes in a pressurized state. Everything in my front system was new, new lines etc. A few months ago I changed the rear cylinders, but not the rear flex line. I was bleeding the rear lines, and couldn't get any fluid out of one cylinder. I unscrewed the line going to it - nothing comes out. I unscrew the other end of the line, the one going to the distribution block mounted to the axle. Nothing coming out. I remove the block, have a look under a magnifier, there's black junk inside the block. One chunk had completely closed one of the ports. I dig around with a needle, solvent, compressed air, clean out the block. Where does the black junk come from? The rear flex line, because it's directly up-stream. I put in a new rear flex line.

Moral of the story - if your flex lines are 20 or more years old, they will look fine on the outside. They will not be leaky. But they will be junk on the inside.

They swell and constrict on the inside not allowing fluid to release. I do a full hand vac on all lines NOT through wheel cylinders. Be surprised how some cheap chink flexible lines look fine on the outside but have swollen on the inside where you can't get anything through them even after just 5 years.

Think I’m going to do other flex line and cylinder. I mean I’ve only had them three years . Just get busy and lazy . Thankyou

Installed for 3 years or sat and then installed after 3 years ? Cylinder could have a rust ridge. FYI I just did total and complete lines on a 63 880 last month and the main metal line leading to the rear was completely stopped up. Held 40 pounds of vacuum.
 
It's probably the topic for another thread, but I really don't understand why brake fluid needs to be brake fluid and can't be hydraulic fluid. Brake fluid seems to be the most caustic rust-promoting fluid in existance next to salt water. Power steering and transmission oil can last forever, doesn't cause (or support) internal rusting or disintegrate rubber hoses. I can't believe that there isin't hydraulic fluid that can tolerate being inside a wheel cylinder or caliper. The rubber seals on drum brake wheel cylinders never melt.

No I’ve been driving it ever since I went through the brakes . I just didn’t do the other side . I replaced every cylinder except the one because it wasn’t blown. I’m gonna do cylinder and flex line . I bet it’s the culprit . I’ll keep ya posted

Make sure your cylinders (left and right sides) have the same bore diameter. I'm going to be checking my rear cylinders to see if that's why I'm getting a pull to one side.
