I’m gonna guess this didn’t catch on

Because I’m not seeing these brakes on any production cars.

Although I do think F1 runs a similar setup? Enjoy that sweet 90’s How it’s Made obliviousness.

I wanna guess heat dissipation, complexity, weight, etc...

I think airplanes run similar ones, just that with many disks between many a pads...

They said it was significantly lighter than a normal brake, but it seems like that must just be because they are using lighter (and more expensive) materials for the disc, which of course can be done with conventional brakes as well.

It’s interesting, though of course it doesn’t seem like we need more stopping force on normal brakes, when a car skids, its because the tire is slipping, not the brake.

yea thats what i thought at first. and with abs systems not skidding is rare

Exactly, not to shoot the idea down, but having an enclosure around them really limits cooling, let alone maintenance, six times the area means six times the pads! Plus more pistons for the fluid to become contaminated, its just too much to handle!

I understand their use in other applications like aircraft whichI think use similar systems of having pads/rotors/pads/rotors... on an on in a sandwich.

As soon as I saw the CNC, I thought “well that doesn’t look cheap to produce”. All the the parts looked like they could be cast, but idk if they would have had sufficient strength as castings, especially if it was mostly aluminum as the narrator alluded to.

“prototype parts” as the narrator says. Casting would be plenty strong, but might be too intricate/detailed

Just because that Porsche recorded many wins doesn’t have anything to do with the brakes. Just driving talent

Casting *might* be plenty strong. Casting and machining are not equivalent. A machined part is generally stronger as you have better control of grain direction when cutting from a block

That’s why you account for that in the casting process, and cast parts generally are bulkiere/simpler, and why you see trick race parts be billet.

No offense, but I’m pretty familiar with different processes and material strengths as an engineer that has designed more than a few metal parts. Sure, you could make a casting for this and it might be sufficiently strong, but at what weight penalty? If you negate the weight advantages of the design in order to produce the part at a reasonable cost it becomes a much harder sell. It’s also possible that some functionality relies on the machining, but it’s hard to tell from the video.

Well seeing as i’ve yet to see these brakes on even hypercars, my guess would be it was too expensive/complex/too little gain. Seems like they’d need a whole bunch of machining after casting aswell, if they intend to have it push the entire way around like in the split view. (0:55). It does seem to sit closer to the disc diameter however, so larger disc for same size required wheel?
