wave and contour rotors

[Jeffrey]

You're interested in Galfer waves because they look cool! We like the way they look as well, but believe it or not, there is quite a bit of thought that went into this patented technology. On a normal round rotor, the leading edge (think toe-in) of the brake pad is in contact with the entire height of the blade as the pressure is applied. Because the contact covers the entire height of the blade heat buildup takes much less time to occur and you end up with heat related problems like brake fade, thermal lockup, and inconsistent braking performance. What the wave pattern does is take that leading edge of contact between the blade and pad and constantly move it up and down, thus minimizing heat build up and its inherent problems. Cool air is also introduced in greater amounts. In addition, through centrifugal force, any foreign matter is thrown clear of the outer rim of the blade and doesn't get lodged in the pad material. Now that I have an EBC Contour Front Rotor and a Galfer Rear Wave Rotor, I figured I would look up the propaganda. I only got the rear because I found an excellent used one on Ebay. On pre08 the front rotor makes a huge difference. The rear looks cool but the effect obviously isn't as dramatic. I guess it could be a dramatic improvement on dirt if you really ride your KLR hard. You don't go around thrashing your rear brakes on street much unless you are psycho or a courier. Jeffrey #3
