Brakes of agonoy and horror.

I recently picked up a Trek 4300 disc.

Ive been riding it 8-10 miles a day this week, no problems everthing just peachy.

So I figured today after my ride I would go ahead and give her a nice once over.

I went about wiping the frame down with a damp cloth, and then sprayed the chain with some one step cleaner lubricant, cleaned with with a chain brush... etc

cleaned brushed the cassette out, just basically wiped everything I could see clean.

Well after all of this I decide to go get the mail.

I hop on the bike and head for the mail box, as I go to stop at the mailbox my brakes begin channeling two dieing elephants. The noise actually startled me quit a bit.

I tried to wear off whatever was causing the noise by riding the brakes back to the house, but all I managed to do was draw frightened and annoyed looks from my neighbors.

clearly i got some of the cleaner or lube on the discs or pads.
So now what? is this going to stop? do i need new brake pads now? an exorcist? or will it eventually wear off?

It depends on how bad you have contaminated your pads. If it's just water on the pad then it should go away soon, but if it's lubricant then you can take the pads out and spray some brake cleaner, do the same to your rotor and wipe it down. It should help.
I would try to save the pads since they're new. It won't cost anything to try. Some people bake them - don't know if it's worth the trouble. Try removing the pads and sand them down with some sandpaper. The worst that can happen is it doesn't work.
never ever use spray lube on a bike

I've saved one before, brake cleaner then bake for 20-30 min at 350* air cool. like you said what's to loose.
Easiest Way, Boil The Pads!!! Seriously Use An Old Pot Boil The Pads,.. It'll Get Anything Off Them.....
THEN USE BRAKE CL,EANER OR RUBBING ALCOHOL ON THE ROTORS!!!

Well>>>>> Verdict?!?!?!
hey man, dont hasten the chef....
Now would be a good time to warn you that do not remove the pad from boiling water by hand:)
Made no difference

Its shocking how loud it is, sounds like 35 suicide bombers in a clown car.

goddammit.
gave it another shot this morning.

put pads in boiling water let the sit

cleaned rotors with mineral spirits.

let the pads cool, then scuffed them with a scotch brite pad


still no good

feels like I have less stopping power now too,
mineral spirits is a petroleum product - no good for rotors.
Rubbing alcohol is way cheaper and good for rotors.

BTW, what was this "one step cleaner lubricant,"?

Even if every thing is clean and as good as new the pads and rotors you still need to bed them.
Don't know if a scotch brite pad would do much. Try rubbing them on some rough concrete (driveway, concrete block, brick.....) if you don't have sand paper -- remove some of the surface.

After cleaning the rotors with rubbing alcohol and rebedding the the pads, the howling may go away.
