banshee disc brakes: how to stop

I recently was a total moron an accidently lubed my disc brakes. They howl like a small bird in agony whenevr I touch them. Not to mention my braking has been horribly compromised. The lube I used is called Tri-Flow Superior Lubricant with Teflon. "Penetrates and Protects." Well crap. I have trip everything from blasting them with water to wiping them off with a towl to "standing" on the brakes as I ride really hard. The latter wakes up all the dogs. The water actually helped and I thought I had it licked; until I used my brakes for the fifth time and they screamed again. Help!

On one hand, this might be a wonderful oppurtunity to upgrade my discs and pads. On the other, I am to broke to do that. Bah!

I have Hayes Nine hydraulic if it makes a difference.

If you can get a blow tourch, quickly blow it over the disc, this will burn it all off, and be as good as new. So i heard. Hope that helps you.

anhydrous isopropyl alcohol could be worth a try, you can find it in any serious electronic parts stores (radio shack is NOT a serious electronic parts store, RS is a joke, sorry in advance to any RS employees).

only difference frmo anhydrous and regular isopropyl is that anhydrous has a .2% mix of anotherr chemical that prevents the alcohol from readily absorbing moisture from the air. It will still work fine. I use the stuff around the house regularly. If you want htough, just get some ddownmixed iso from the drugstore (aka rubbing alcohol) alcohol tends to dissolve oils and displace water quite effectively.

If it was my bike, I'd remove the disc and clean it with lacquer thinner. Then I'd replace the pads, which are undoubetly contaminated.

I don't think that using a blow torch on a closed system hydraulic brake would be a very smart thing to do.

What about the pads? And I will try it with a lighter. Thanks!

Haha, in the time it took me to see the first reply and write my own other ideas have come. Thanks a whole lot! I do have the alchohol. I tend to frequent serious electronic stores as I am an amateur radio operator. Thanks much for the advice. How much for new pads, roughly?

If you have the access to a torx wrench, take the rotor off and take the pads off and boil them, that way usually gives the best results.

Steve said the magic word, "brake cleaner". It's made especially for this situation. But the other chemicals and methods should work just as good.
