<p>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 said vanes having a proximal end 124,126, a distal end 132, 134 and a mid-portion 128, 130 extending between the proximal end 124,126 and the distal end 132, 134, at least one of the distal end and the proximal end 124,126 of at least half the vanes having a first cross-sectional area, the mid-portion 128, 130 having a second cross-sectional area, the first cross-sectional area being substantially greater than the second cross-sectional area. The vanes 132, 134 can include a T-shaped portion 138 adjacent the distal end 132, 134. The vanes 232, 234 can include an hourglass shaped portion. The vanes 332, 334 may taper from the distal end to the proximal end. The vanes 332, 334 can include a thicker cross-section adjacent a peripheral portion of the rotor. <IMAGE> <IMAGE></p> |
