I installed new rear brake shoes - what did I do wrong?

Hi all;

While changing the tires on my bike - a 2009 C50SE - I decided to change the rear brake shoes while I was at it. Everything is back together, but when I tested the rear brake it failed to engage the shoes with the drum. So now, with the brake pedal fully pressed, the rear tire still spins freely by hand, as if the brakes weren't there at all.

I'm sure I put everything back exactly as it was, with the exception of using the new shoes, and I didn't touch any other part of the rear braking system. I triple-checked the shoes to make sure they are the correct parts (they are). The adjusting nut would have to be put in a ridiculous amount on the brake rod to give me any braking action - far, far more so than what it was before I replaced the shoes.

I could rectify the situation by moving the brake arm back (turning it clockwise) a few notches, but that would mean that the gap in the brake arm is nowhere near the 30-degree offset from the line on the end of the camshaft. This is the offset recommended in the Clymer guide for my bike and appears to be the way it was based on pics I took as I was going along.

Moving the brake arm would be the easiest solution, but this would make the gap in the brake arm actually line up with the line on the end of the camshaft instead of being offset. This would be in contradiction the Clymer guide's directions and my own "before" photos. The cam would also be constantly engaging the brake shoes in this position (pushing them apart and not allowing them to sit at rest) once the brake arm was back on the brake rod - although this may not be an issue so long as I'm not dragging the shoes in the drum.

Any ideas what I did wrong and how I can best fix this?

Did you reconnect the torque rod that keeps the brake plate locked in place? Did you make sure the bottom (half mooned) ends were securely on the post and springs were attached?

I can head East or West, it doesn't matter as long as it's on 2 wheels.

Pretty sure to all the above. I'll need to pull the rear wheel off again to verify the shoes are in place properly, but I was playing with the brake arm and watching the shoe's action and everything seemed fine before I put the assembly back on the wheel.

But when I put the brake panel back on the brake lever was in a downwards position and ready to be hooked up to the brake rod. Should the brake lever have been in a different position, say pointing upwards, and rotated counterclockwise to meet the brake rod? Could I have installed the shoes with the cam in the wrong "resting" position?

Check the spring at your brake pedal. It's rather small and see if it came unhooked. It's unlikely but it could have. As long as the springs are on the brake shoes, rod is attached, and cam arm hasn't been moved, I'm not sure. I think the cam is the same on both ends. I just replaced mine and everything works as it should.

Did you make sure the round rod that fits between the brake arm forks is there? The rod goes thru it before the adjustment nut on. If it fell out there's nothing to actually pull on the brakes.

Open it up, take a picture, we'll fix it.

Yep, everything is in place. I step on the brake pedal, everything moves as it should, the brake level turns the cam, and...no brakes. I'm sure it's just an adjustment issue, but I'm also fairly sure I put everything back the way it was before I pulled the wheel off.

I've got absolutely no clue as to how to proceed. I could simply move the brake lever as I suggested doing, but I'm very leery of doing so because it would put the level in a different position than before and would not be positioned as shown in several guides.

That'll take some time. Not the bike, but taking the pics. I just bought a new phone and I'm still learning how to use it. It took me longer to setup the phone than it did to pull the wheel off. ☺️

How much adjustment rod do you have extending from the nut?

Only thing I could think of is you turned the lever that holds the adjustment around when you had it off the bike, that's the only thing that would prevent the brakes from working. I don't know if that makes sense

If I were testing things, I would go ahead and put the adjusting nut at what you think would be a ridiculous amount, and see if you get brakes. In my experience adjusting them each time I change a tire, there isn't a whole lot of turns of that adjusting nut between "where are my brakes?!" and "hey, they're grabbin' pretty good."
