Love this video, that guy has Def lost more scotch in those hills than hes found

Haha, I 100% bought the chips for the TdF packaging.
Nice trip!
Your only sin is buying Vico instead of Brets chips
UPDATE
I fixed it! Thank you so much to everyone here who helped!
My findings:
It all hinges on the notches the spring slides in to.
If the notches aren’t lined up and/or the spring slips out of the notches when the brake is pulled, one of the brakes gets stuck.
So to center the brakes, focus on the notches not the brakes.
Whichever pad is sticking, make sure the spring on that side is resting on the bottom of the notch and not the top when you center the brakes.
Otherwise, when you use the brakes, the spring will get pulled down to the bottom of the notch and the brake on that side will get stuck.
My notch is much larger than the one in the image so there was a lot of play there.

I think I finally figured it out. I took the whole thing apart, examined it, and re-assembled it.
It seems to all hinge on the notches the spring slides in to. If the notches aren't lined up and/or the spring slips out of the notches when the brake is pulled, the brakes get stuck.
The mechanism works because the "head" of the bolt is in the middle. It's a double ended bolt basically. The nut on the end that goes into the bike only attaches it to the bike, and it's tightness has no impact on the functioning of the brake, other than stopping the bolt rotating.
There are 2 nuts at the other end. The inner one needs to be loose, to allow the brake leavers to rotate freely, and the outer one is tightened against the loose one to keep it in place.
I'll try making a diagram when I get home.
Forgetting my bike and looking at the photo, the paradox is that B is supposed to push D around the center bolt but at the same time, not allow that to happen. I can't wrap my mind around how this mechanism is suppose to work. It shouldn't.
The problem is that physics dictates that the whole assembly is supposed to rotate around E. But functional brakes use some kind of unexplainable magic to keep it from rotating around E.
I ended up taking the whole thing apart yesterday so I can spray it all with WD40. I took the spring out and I don't think I can get it back in, so I think I'm just going to duct tape what's left to the handle bars and go with one brake for a while.
The nut at the back of the fork is what should be holding the assembly in place. Maybe try making that nut tighter?
Without seeing anything, it sounds like something is wrong with E.
You can post video to catbox.moe.
Probably? I never tried.
For the bike you said you have, at least one pic shows dual-pivot sidepull brakes; other pics show single-pivot. If you have dual-pivot, that is a different adjustment procedure. If they are actually single-pivot, you need an offset brake wrench to get them adjusted properly (assuming they're not damaged and the brake post is the correct fit).
The spring is there and working. The problem is that, if we call the center pivot bolt E, when B pushes down on D, A C & D roll around E.
I hate these things with a passion. In the past ive just lived with the suck but if you are motivated I think replacing the spring is usually the advice I've heard. Honestly though if your frame and fork are compatible with v brakes or cantilevers, I would change to those
Photos or video would be very helpful.
Yeah, pictures, or better yet video would be great.
Can I post videos in here? I could maybe video what's going on.
There should be a spring inside between AC and BD so that when you release the brake handle it opens up again. If that is not happening you may need to separate the two and replace the spring, or maybe there are notches so you can increase the tension.
By hand, yes. I took them off completely last night and I can squeeze them like a hand gripper exercise.
When I press the brake handle, A goes up and pulls C to the rim, and I guess B goes down and pushes D against the rim. But when I release. D stays against the rim.
It seems like when B goes down it twists the whole assembly around to the left.
Without seeing exactly what your setup is, it's very difficult to diagnose your precise issue. The brake cable could be too short, your anchor bolt could be too long/not tight enough, the brake return spring could be bent/damaged. If you don't have an offset brake wrench, getting any of this right will be tricky.
That's weird it's not coming up.
It says "this video is unavailable"
That's weird it's not coming up. Every video on fixing side-pull brakes are pretty much the same but this is the name of the video I linked to "Adjust / Center Side Pull Caliper Brakes That Are Hitting Rim Uneven" by Ivans Bikes Bmws.
My bike is an Outroad Road Bike 700C Commuter Bicycle
When you tighten them can you still freely open and close the arms? Can you manually actuate the brakes by pressing c& d (on my image) towards your rim?
Ideally when you press your brake handle the cable should pull A up, pushing C against the rim, which causes B to go down pressing D against the rim.
Edit: I had directions backwards
They're just like that.
The video isn't coming up for you guys?
