This looks like a very effective bicycle brake. I've never seen this type in real life, but my logic tells me that as the brake pads wear down, the amount of pressure on them increases because the levers get closer to the "over center" point. It's similar to the Vice Grip pliers that increase the leverage when you adjust them so that you can squeeze the handles closer toward each other.

Interesting scene, and nicely done.

Yes. Thanks. The brake leverage is non-linear and increases the closer you are to the "over center" point. The problem is that they could lock up if you get too close to the over center point, that is why there is a stop on the longer toggle link. So they work, but the adjustment (by moving the pads in or out) is not user friendly.

Wow, s_noonan, you could earn a lot of money if you init a company to sell this new bicycle items!!

Nice work,keep it up!
