Why not a single rotor w/ 2 or 3 calipers?

Hey Mindcore-

You can lock the wheels of the Tercel up because you have enough brake... for those tires... at that given time.

It's a balance- in the end, braking power is a limited by tires, then brakes, then the car's/your ability to modulate it. And on top of that, we haven't even gone into extended braking capacity, and proper heat dispersion for both tires and brakes.

Hey krazik,

You will see two calipers on some older race cars but most race series banned them. Two are not legal in F1. The problem with two or more is cooling and weight. Plus with modern 6-piston caliper clamping force is not the problem. You will however see two brake calipers on the F50 in the rear. One is for the rear braking and the other is for the parking brake. Racing brake have adjustable drag and will not work with the parking brake.

Cheers,

That's what I mean Nick, Other then heat, and maybe a few other things I don't know about, how will these new brake type make you stop faster? allow you to user wider rubber? but then that changes handling. Your right, a balance is needed. I don't see brake systems like this being used in average cars anytime soon.

Mindcore what do you mean faster? Big brakes on racecars are not to improve 60-0mph but to improve the 200-0mph over the race distance. The Tercel example used above is very silly. The brakes on the Tercel are crap just like the rest of the chassis and the tire size is not the answer. The brakes lock easily because the chassis dives during hard deceleration the weight transfers from the back to front abruptly, and this in conjunction with the hard compound tires cause the loss of traction, so the front wheels lock. Locking up brakes a low speed takes much less force than at high speed! What is the highest speed you think the ABS will come on in our stook? From my estimation, I would guess about 50-60mph on good pavement. Brake balance and chassis dynamics are critical in overall braking performance. But don

Well, I do know how brakes work, When I said faster I meant the time from X speed to a stop. And My original point is, if you read back from the begining is that just by being able to lock your tires does not mean you have all the braking power you need. I agree that there are many issues that are involved in stopping or slowing down a vehicle. But just how much of that process is just the brakes? As you have said and others as well, it's not the only thing that decreases your stopping distance.
