Contaminated Disk/pads


Jaffacakes

Recommended Posts

Some tart covered my disk rotor in 3 in 1 lubricant oil and I just can't sort it out.

I have tried putting my rotor in the dish washer, going down a hill with it on then covering it in water, I have scrubbed my pads in hot soapy water which cleaned them up nicely but stays like that for about 10 seconds, scribing my rotor for about 20 mins and also attacking it with fire which didn't work.

The worst part is that the pads and disk are both brand new :( . Is there anyway I could sort it out or will I have to replace them?

No- harsh sand paper is bad for a disk rotor. if anyhting, use fine wet and dry.

Putting your disk in the dishwasher should work, but if you didnt do naything about the pads as well, then it wont.

Try the dishwasher again, and either replace pads or boil them, then sand the surface off and re-bed in the brake- it will be like new, so will take a while to get back to full power.

None of its working :( . My harsh sand paper is completely black, the pads are still as oily and boiling didn't do anything. I think I will have to waste £45 now :angry: That's all hope of me getting a new front wheel just because someone thought it would be funny to cover my rotor in oil... Tw**s.

re-bed in the brake- it will be like new

It's not even fully warn in yet, thats how new it is

Try just new pads, get the rotor, give it a proper scrub in strong degreaser/spirits and then wash it all off properly, to make sure theres no trace left- when spirits evaporate, they can still leave a residue containing the oil. It all need to be wiped off while still wet, and repeated. also try dishwashing again, coupled with just new pads should save you some money.

Also make sure the inside of your calliper is clean, as you dont want to recontaminate parts when you reasemble!

Water wont remove oil....

Best bet is to get some degreaser of some kind, Lee always uses (i think) carbon choke cleaner. meant for cars but does an awesome job.

Try any kind of degreaser :S Ive not really bothered with mine but its never recovered from hobbsie smearing sausage fat on my disc at nass :(

If i were you I'd make your mate pay for the stuff before setting him on fire :) as for the disk (can't help you with the pads, they could be well and trully f**ked 'cause the pad material may have absorbed the the oil) but the disk! burn it on a gas cooker till it's black, clean off the black stuff, DO NOT PUT IT ANYWHERE NEAR YOUR PADS because the pads will cover it in oil again I heard some people put disks in a pan of water, and boil the water till the water has evaporated (and in theory the oil etc goes with the water) and keep doin it till the disk is dry...

on a semi-related note: when putting your disc back together, make sure you do everything back up nice and tight because just now on my ride I pulled my Avid and the cable slipped through the holder thingy. I wasn't angry as I was riding nicely and it somehow magically made me Avid better after I tightened it up.

Wo! :)

Petrol only contains oil if It's been mixed for a 2 stroke :P Petrol will get rid of all the shit off the rotor, keep wiping with clean (dip, wipe, swap cloth, dip, wipe, swap cloth etc) petrol and it will get rid of all the oil on there. Oil will not boil away, that's bollocks, you'll just get all the water boiling away and it will leave a nice shitty residue on your disk and on the bottom of your mum's finest cookware. When you boil a disk, why not put a squirt of fairy liquid (or equvalent :P ) in there to break down all the oil that comes off the disk? It cant float to the surface and cover the disk when you pull it back out then...

Yeah the water didn't do anything, I put fairy liquid in there aswell which errupted like a volcano and went everywhere and yes there is alot of residue on her finest cook ware :- .

Im just buying a new rotor and new pads >_< .
