fork oil on brake pads.

Hey guys well i took my 919 out after sitting for two weeks... i know i shoulda never let her sit that long here in sunny so cal... but sking and dirbiking were more important. Anyways i had a small fork seal leak and when i parked my 919 2 weeks ago i got a coupla drips of oil onto the front left pads. and it was noticible how much less she was able to stop when i took her out on the short ride today.

So what are ways to get oil out of pads and off the rotor. Im currently soaking the pads in some 91% isopropol alcohol and ill buy some break cleaner tomorrow.. I have heard that you could take a torch and essentially burn off any oil that its impregnated into the pad so ima give that a short unless people say otherwise.

Thoughts opinions and ideas welcome.

Pitch the pads.
The fluid will have wicked into the matrix.
Alcohols are not as strong a solvent as likely needed, and the strength likely needed would break down the binders (like acetone or lacquer thinner).
Get new pads !!!!!
Clean the disk repeatedly with a really hot solvent like acetone.
Lacquer thinner as second choice and easy to clean.
If you can't buy acetone, you may be able to get it disguised as pre solvent weld cleaner for plastic piping, Oatey being a brand I found at Home Depot.
Lacquer thinner will work nicely, noting I tend to fall into the trap of using 10 # solutions for 1 # problems. And Acetone is seriously nasty stuff, especially in confined spaces.

WARNING !!!!!!!!!!
Hot solvent is a figure of speech, and does not mean heat it up - DON"T !

I wouldn't bother with them. I'd toss them out and buy new, but YMMV.

If your replacing brake pads, replace both sides. OEM pads work good, I'd stick with em





.

Well, fire the engines! Spur this iron space-pony on!

Fork oil is VERY slippery...more slippery than motor oil by a longshot! Take the advice of the guys above and replace your pads...both sides if you want to do it right.
Acetone, brake cleaner and laquer thinner will all leave a residue on the rotor that will affect braking performance, especially laquer thinner, but it's necessary to use one to break down all the friction modifiers in the fork oil. Wash your rotors with hot soapy water (liquid dish soap) and a scotch-brite pad to get rid of the residue. This will also help get rid of some of the embedded brakepad material that builds up on your rotors as well. You might even want to scrub your rotors again after bedding in the new brake pads.
