I just got a pair of Zipp 303's but my Record brake pads smell like there melting on steep descents. WHAT ARE THE BEST PADS FOR CARBON RIMS ????

My friend has gone through all brands and find these work best on carbon.

I would suggest calling Zipp. Although Corima is generally accepted, when I talked to Zipp they said the Campy pads would be fine and they have. Now either our decents could be different or our braking.

Your record pads are melting. I called Zipp about mine and they told me that the hard rubber Record pads transition into a melt phase at high temps because the do not dust off like the DA pads. The DA pads wear out real fast because the hot shredded pad material gets ejected from the pad, in particular they say DO NOT USE CORIMA PADS which can actually turn to liquid from the brake heat. The Corima and Shimano rims have a pure epoxy/mold release surface with no abrasives at all and need special pads, the Zipp rims are very aggressive. The DA pads are not designed to wear as well as the Campy and therefore wear away much faster and do not have the same melting effect. Remember Jan Ullrich going off the mountain? They say he too used Corima pads on Zipp rims until they melted away and there was nothing left.

They gave me two options, one brake hard and late, do not drag the brakes. This makes sense, good descenders are like race car drivers, in deep, brake hard, turn in, accelerate out. The rest of us brake up to the curve, brake into the curve, brake through the curve, and continue braking up to the next bend generating lots of heat. Finally they say try the Kool stop Salmon colored pad. It is softer and wears out faster, but it seems to dust away instead of melt, more like a DA pad.

Thanks for the detailed response, I was suspect on the Corimas but many responses to e-mails all motioned towards them. QUESTION - my Zipps are year 2000 wheels without the new silica compound molded onto the rim like the current 303's. Do you think this would make any difference ??

Thanks in advance for the response.
