baked brakes - recipe?

My pads are contaminated and before plunking down the change to buy new pads I was going to throw my old ones in the oven to see if that helped... just wondering how hot I can make it and how long I should leave them in?

I tried scrubbing the pads and rotors with some white lightning degreaser for chains and rotors and it really didnt improve much at all. I can squeeze as hard as I can and BARELY lock up the rear (really bad). My pads and cables seem adjusted right so I'm guessing it's just bad pads (even though they have plenty of thickness left). They're Avid BB5's, btw.

Try boiling them? Sanding if you HAVE to.

Boil, scrub with metho, dip in petrol and light them on fire. Sand back and you pads should be good. My mate dropped his pads from the brakes he was bleeding into his used bike fluid container, so that is brake fluid and fork oil, he used the method above and they were great afterwards.

I would suggest 450-500 degrees in an oven for about 20-30 minutes. I'd do this in a toaster oven outside somewhere since they can create some smoke. I wouldn't put any water or chemicals on them I'd just try and bake out the impurities. ALso be sure to scuff the rotor surfaces with sandpaper before you put the pads back on. This will clear the rotor surface and allow them to re-bed.

Thanks for the help guys. What is Metho?

I'll try baking them.. if that doesnt work... boiling them... then sanding... burning... until I HAVE to buy new pads anyway.. lol

I'm not sure how they got contaminated... I'm thinking it's when I splashed through some pretty big puddles with probably some oil mixed in... that's all I can think of.

In Australia you can buy methalated Spirits, it is pretty much pure methanol. Look for White Spirits

Edited ethanol->Methanol

How about using IPA? Is this good for cleaning pads or rotors?

That sentence is making the chemist in me cringe.

Solvent first, then boil, then bake if you have to. Baking is going to leave behind hard residue that won't come out easily.
Or, just buy new pads and be more careful next time.

No, but it'll make your pointless efforts to do so more enjoyable.

Sorry, changed the ethanol to methanol. I meant the one with one carbon not two....
