I've seen the disc brakes on my sister's car, and these look almost exactly the same. Excellent work! You should make a Youtube video showing them in action.

i love the design but it doesn't generate much force in a large scale motorized vehicle....for that you need something to lock the drive train in place and then unlock it..... ill help you work on your system..... my congrats for a perfect first try

Not a bad design - looks good. I imagine like my system it just doesn't generate much actual braking force. I use dental floss to transmit "pull" from a pedal to compress two pads against a small wheel - you can see in the two cars I have on here. The design is getting there - next stage to grind down some of the big 40 tooth gears to make big disks. Dental floss is a Lego wonder material for transmitting force by the way...negligible stretch and can go around corners on pulleys really nicely. I haven't really seen anyone else make a serious attempt at scale brakes - nice job!

Your design is ingenious and there is no doubt about it, but having a plastic brake disk and pad doesn't create much friction and would be impractical to use on a large scale car, no offence..

this is a realistic and creative break system 10/10

Good, but u kinda dont get it

can you see the grey part with the 2 holes next to the red part on the other side of the disk? - that's the brake "pad" which's moved by the flex over the black beam with 3 holes.

I have to say that I don't see how it can work. Can you demonstrate somehow?

Very nice, I've been working on a brake design myself but this seems to work a lot better than what I've come up with.

I like it. One application it would be very good for is a heavy trailer going down hill when one motor wouldn't provide enough "engine brake" to slow it down. Thanks for posting!

exellent idea! thanks for share it!

Brilliant. I've made pneumatic brakes before but these look so much better as they're so compact (and actually look like the real thing too). I don't know how well they work but for innovation you desreve nothing less than 10/10 : )
