Well of course you never know if such things will actually make it into production.. but this one seemed simply stunning to me and I wondered why nobody considered it in the past (not that I know).

I ready about this new dual disks brake system on evo and I think it deserves to be seen! I just see positive points: more cooling surface, lighter pedal, more force applied, better feel, lower diameters so weight won't really improve...

You can read more about it here: http://www.delphi.com/pdf/e/br_max_torque.pdf

Hahaha, they have this on Mountain bikes!! Seriously, 'Hope' are in the process of developing it!! I bet you never knew bikes were so cutting edge!!!!!

LOL I bought my last bike (a sweet Cannondale) probably 10 years ago.. still not disk brakes at all.. :D

I am trying to find a pic, but this is such 'hot' news that there are none yet. Only one magazine has it, and the only pic I can find is a phone pic and really bad quality!

have a click of the link, does it work?

As I said, really bad quality, it is a mobile phone, taking a picture of a Magazine!

What about my kind of brake system?
Water-cooled internal disc brakes (so that it keeps unsprung masses down), with a driveshaft-powered clutch-engaged water pump (which generates some braking power itself) to keep the cooling liquids flowing...

The only thing you'd need for that is money and strong driveshafts.

Explain internal disc brakes!

I am finding it hard to visualise how they work!

Well, internal brakes are close to the differential housing. Obviously, that means they are far away from the airstream as well, that is why you need to cool them by liquid cooling.

I didnt realize someone made a system that was water cooled.. Most of the jackass mustang people run the internal rotors then whine when the suckers overheat...

A fool is born every minute.

what kind of Mustang are you talking about? the Ford's they don't have internal brakes. NEVER seen them on one either.

Aftermarket.. remember I run in the road racing/autox crowd. The less successful wannabes tend to focus on a certain kit ive seen a few times with internal rotors..
The good ones just laugh at them.

The stock setup of the mustang sucks.. but thats for other reasons..
Particularly qudra bind in the stick rear and undersized rotors.

The cobras independent has much bigger problems according to most of thepeople i know.

I had an idea once...

Why not apply the braking pressure to the area surrounding the axle on which the disc is attached to? The reason why brakes heat up so much, is because the pressure is applied on the outside, which, due to the distance from the main point of "spin" (for lack of a better term) multiplies the amount of force needed to stop the discs from spinning.

Now if you had brake pads that circled the axle (sort of like a mini-disc) on both sides of the main disc, and made the two pads clamp down, (like regular brake pads) it would slow down the main disc's spin quicker since the force is directly applied, as close as possible, to the force's main area of origin, and create less friction and heat, therefore reducing the risk of overheating.

It's a physics thing.

Hey TT, remember Kchrpm from over the the GTF? He works at Delphi, he mentioned this quite a while ago. I'm not sure what, if anything he had to do with it though.

I think it's a pretty cool idea, it'll be a long time before we see it on a car though. The numbers make it seem quite impressive, but I'd like to see it's performance while on a car. Rather than a bench.

yeah, it does look like a really cool idea, and i think if they wanted to they could make it work...i dont think it's quite as odd and complex as it seems. I just don't really think that the idea would take off simply cause of pricing...i'd think that for the price of a system like this you would prolly be able to get a set of brakes that work pretty much as well as this one does, but the conventional brakes would be more simple and have fewer moving parts, which means less of a chance of something going wrong.

they have systems like that available for some r/c cars and trucks (the gas powered ones...electric ones use reverse current to slow down)

To be honest I had that exact idea for a very long time and I always thought why no one is actually doing this. Its not rocket science.

Anyway nice to see this actually being worked on.

sir GT, the problem with your idea (that i see/or think might be a problem) is that the axle is covered. and if you uncovered it to use the brake idea it would be pointless almost. teams would rather not carry the extra weight. and why would you want the mini-pads to clamp down close to the axle? there would be more tq applied to the pad there. if anything you would want them to the farthest away fromo the center of the axle so you could actually multiply the leverage of the brakes. i think thats what you were saying, its kinda unclear. :D

also, we discussed this subject a wile back over at a car board i'm part of. anyways the only logic i can think of is that in racing if you had brakes like this you would have to have to get new wheels to and such to fit them on (complete re-structuring of the wheel) and even then, you would have to use a bunch on small pistons which might not me as effective as the larger ones.

wheres that dude that works for delphi, maybe he can enlighten us
