Default Full-contact Disc brakes

What ever happened to that idea? Newtech brakes was the creator of them I think, I remember seeing them a while back on how stuff works. Here's a link scroll down about a 1/4 of the way:

I think one big issue is weight. The nice thing about current brake systems is they can be very light. With the full contact system pictured, you are putting quite a bit of mass out there at the wheels. The thermal control is nice as there is a LOT there, but it's a compromise. As well, the contact area isn't that big of a deal. The benefit with more contact area is better wear.

Expensive and pointless comes to mind. The brakes aren't the limiting factor when it comes to stopping the car.

If they have a ton of mass in there it'll help with brake fade.

Fade? What fade? If you have fade on the street then you're using the wrong pads. I've run both the LGT and Brembo's on the track. They don't fade at all. Even with R-comps.

I think full contact calipers would make cooling the brakes that much tougher.

It's not the R-compounds that will fade the brakes. It's the combination of high speed, agressive pads (think Performance Friction or Panther XPs), threshold braking and the lack of brake ducts. I've cooked Motul RBF600 at the track with agressive pads and street tires. I installed brake ducts and was fine. I also recommend Castrol SRF and titanium plates between the pad and pistons.

Do you end up with more torque? It might be harder to modulate than normal brakes :shrug:
