Wanna run vented rotors on the rear?, Wanna have a parking brake, too? Options

Clay Perrine's solution

Being discussed on the Bird board now. He's prepared to make up 50 sets of the brackets if he can find buyers. The caliper is an off-the-shelf Wilwood part.

One of the problems with using the stock rear calipers is the piston area is too small. This is why, when you run big front brakes, you can use a tee instead of a prop valve. The rears have so little power in relation to the fronts that a prop valve would be fully open, anyway. To get more actual braking force at the rear, you need calipers back there with bigger pistons. Once you do THAT, you (may) need vented rotors back there to handle all of the heat that wasn't generated before, because the rears were doing so little in relation to the fronts. With stock rear calipers, you'd never need vented rotors in back.
