As contact area goes down, pressure goes up, so stopping torque should remain constant. Pad heat and wear will increase.Originally posted by Bryan Hester:
Rob the wave disc was designed to self clean on motorcross bike in muddy conditions and they do this very well. but less disc contact area = less stopping torque.
I've also read that wave rotors were designed to decrease heat at the leading edge of the pad. In a standard rotor app, there's supposedly a temp differential between the leading edge and the rest of the pad. By waving the rotor, the leading edge contact is not constant, decreasing the temp. This strikes me as BS, because it seems like you'd get the same non-constant effect from holes in the rotors, and I don't think the phenomenon holds true as described.
