Hope Mono Trials not Grabbing...

[echohi]

Hey guys,

Had my Mono Trials for a bit now and am loving it, however, I went on a ride in Toronto this past saturday and now it's not grabbing at all... any braking now with cause it to shudder and squeak pretty loudly. Not only does this suck when I ride downtown but it is also not giving me any power. A full out grab of the lever barely slows me down. So, I was just wondering if you guys had any suggestions on fixing this. I know rubbing something on the rotor makes a difference but I can't quite remember what it is. Any help would be great, thanks guys.

rubbing alcohol and clean pads

[sethman]

sometimes even small amounts of oil can get on your rotor and be obsorbed into your pad. my friend got a drop of sweat on his luise rotor and he didnt know what it was for like 3 months , and when he finaly figured it out the pads were ruined. alcohol or paint thinner.

good luck , sethman

If the rotors and/or pads are contaminated with something, you gotta clean them really well. You are usually hosed with the pads if you have oil on them, but you can clean the rotors with denatured alcohol (soak them), wash them off with something like simple green after that, then put them in your dishwasher so the high heat gets any residue off.

Pads - just buy new ones. You can sometimes save them with baking/using a torch (done it a few times, but it is hit or miss, and very smelly). You'll muff up your oven if you do it inside, so either get a toaster oven for garage use and try baking them at 350 for about 10 minutes, or get a torch, hold the pads with pliers of course, and heat them up until they turn black. Grab some sandpaper, and sand off the surface of the pads where they want to hit the rotor, and just re-bed them in like they were new. Like I said before, just buy new ones to avoid getting injured or ruining something important.

Do the baking/torch thing at your own risk, search the net for a better instance of how to do it if I didn't describe it well. YMMV with it remember.

As said above, it's really easy to clean rotors, and really hard to clean pads. I've had good luck with the heating method. Any oily substance in there can't be removed, because the pad material is so porous. You've got to burn it into dust! Here's my long post about reviving disc pads, and please search next time. Disc brake power is a very popular topic.

Test contamination with splashes of water on the rotor/caliper. It's likely you'll have awesome power restored for a few minutes until it dries out, then crap again. If this is the case, you've been contaminated, and the fix is easy. HEAT!
