Juicy 3s and oil/contamination

Hello, everybody. A month or so ago, I got a brand-new set of Avid Juicy 3s at bargain price. So far, I'm really happy with their stopping power and modulation (I run mostly street/dirt). However, I've had to clean the rotors and pads THREE TIMES over this month. I didn't touch the rotors, oil from my chain hasn't touched 'em, and yet they started somewhat out of nowhere to scream like an elephant in heat, and their sotpping power went down to nearly zero... Luckily, I keep a spray gun loaded with Isopropyl alcohol at hand, as someone suggested in another thread.

I come from mechanical Shimano 465s, and ride the exact same places. Are the Juicys sooo damn sensitive to dirt/oil??? My mech brakes weren't that anal...

Has anybody had this problem? How do you deal with it?

Thanks in advance,


Luis

OK, I'll see if I could get Copperslip or something like that (I live in Argentina). The funny thing about the squealing is it isn't consistent. I mean, when my old 495's got the pads contaminated, they started squealing (and stopped braking), and continued that way 'till I changed the pads and cleaned the rotors.

So far, the Juicys have been braking smoothly for about three weeks, with just a couple of squealing/fading episodes in the middle. They didn't even happen in the same conditions, one time I was jumping in the city and the other time I was riding XC-like trails in the woods. I'm no John Tomac, or anything like that, so speed/overheating doesn't seem to be the the cause. In both cases, the fading/squealing dissappeared as it arrived: magically.

I'm kinda getting used to it...

Anyway, thanks a lot for all the answers. I'll try to get the Copperslip.
