What's the best way to get oil off my brakes?

I've wiped as much as I can off the disc but it still seems reluctant to stop. Will I have to take the pads out and douse them in petrol or something?

As above but use a tooth brush to clean out all the holes.
It's possible it's soaked into your pads a bit too, in which you'll either have to live with it (and be aware you will run over several kittens per journey because of this!) or get some new pads.

I'd wash the discs with brake cleaner and buy new pads. For the sake of £30 I'd rather be able to stop.

It's just had new pads though. I don't want to replace them again Sad

Seriously though, I'll douse the whole lot in brake cleaner, and if it's not right after that I'll replace them.

Well, to be blunt, you shouldn't have tried to ride the bike with oil on the discs!!

But Marjay, Oh Great One, I didn't realise there was oil on them until the first time I tried to stop.

Once you've cleaned all the oil off, rub the pads on a rough surface which should take off any remaining oil ... something like a paving slab should do it Thumbs Up

Oh and of course, take it easy until you feel that the brakes are 100% Very Happy

From what I've seen, the oil can soak a fair way in; it's often far from just on the surface.
My NSR fork oil used to leak over the front disc quite badly. The braking was quite variable; but still had enough to stop; though to do stoppies you might have to do a bit of lighter braking first to burn of a bit of oil.
In the end, you're probably still going to have better braking than the majority of 'classic' bikes, etc; just need to ride appropriately to the situation Smile.

Well, I've sprayed brake cleaner all over the disc and pads but it's still not quite right. No oil on the disc now but it still won't stop properly.

I've sprayed it again around the pads and left it to soak in for a few hours, with a bit of luck that will sort it, otherwise i'll take them out, soak them in petrol, burn them and then sand them down slightly. Apparently that works.

Hi

Take the pads out and use brake cleaner on them. Wouldn't expect it to have as much effect if the pads are still in place.

All the best

the dangeorus method I did was to ride it off, my NTV oil filler cap wasn't tight and it leaked all over my back brake, I stopped wiped it off and continued riding another 200 miles , the oil 'burned' off and left a fine film of dust on my back brake, took it to an MOT 3 weeks later it passed.

Unfortunately it's the front one, if it was the back I could live with it.

The mechanic who put my fork seals in did a fantastic job, and then lost all credibility by leaving one of the little bolts undone at the bottom on the offside fork, causing it to drip oil all over the brakes as soon as I put the fork back on the bike.

I don't even know why there's a bolt there. It's obviously not to drain oil out (as there's an allen bolt to do that in the bottom of the fork leg). Perhaps it was the reason why I couldn't seperate the forks Very Happy

It is there to drain the oil out. The hex bolt is not to drain the forks, it is there to hold the forks together.

All the best

In which case, I can't believe he didn't tighten it up! What a mong!

On the plus side, he did do it for £18, which saved me a huge amount of hassle.

I would try and salvage the pads if this happened to my pushbike's pads....maybe..

On a motorcycle I would buy new pads.
But if they are brand new and you do really want to salvage them, this is what I used to do-
Grab a large, flat file. Clamp in vise with large flat side facing up. Scrape the pad up&down the length of the file. Repeat until at least 1/3rd of the pad material is taken off.
None of that messing around with sandpaper or the sidewalk.

A mechanic's told me to burn them, wipe the oil off, repeat until all the oil is gone and then sand them with sandpaper. I'll try that tonight and report back.

Damn it, was about to suggest heating them with a hot air gun. The oil will rise to the top wipe it off and repeat until your happy then give them a good rubbing with some sandpaper.
