Abstract
A disc brake including a pair of friction plates arranged coaxially in a parallel, spaced-apart relationship and a plurality of vanes extending between the pair of friction plates, each of the vanes having a proximal end, a distal end and a mid-portion extending between the proximal end and the distal end, at least one of the distal end and the proximal end of at least half the vanes having a first cross-sectional area, the mid-portion having a second cross-sectional area, the first cross-sectional area being substantially greater than the second cross-sectional area. The vanes can include a T-shaped portion adjacent the distal end. The vanes can include an hourglass shaped portion. The vanes may taper from the distal end to the proximal end. The vanes can include a thicker cross-section adjacent a peripheral portion of the rotor.
