Help with Disc Brakes

stmol32

I've done something very foolish. I was doing a bit of routine maintenance on my bike and I went a bit mental with the WD-40 and I sprayed the discs.

I didn't realise what a silly thing I'd done until next morning when I tried to brake and it took a metre or two to stop.

My question is Does anyone have any advice on what I could do (other than buying new pads and de-greaser which we'll call plan .

Thanks for your help.

Oh Lordy!! :eek::eek:

Isopropyl alcohol will remove the oil. Clean both discs and pads then go for a cycle and work the brakes hard every few metres to wear down the pad surface.

Also, maybe you should leave the maintenance to a professional in future

You shouldn't use WD40 anywhere on a bike, its too light a lube to be of any use and it will dissolve any of the lube already on there.

Chances are your pads are gone too, you can try what waraf said but the WD40 will have soaked into the pads.

Damn, not the greatest idea ever.

MucOff do a disk brake cleaner that is quite good IMO,(probably contains that isopropyl alcohol) and might do the job on the discs. You might take the pads out of the calipers and give them a rub with a fine grit sandpaper also but if there's sinificant ammounts of WD40 soaked in as Ciaran says - they're toast and will need replacing.

I'd toss the pads to be honest, chances are the wd40 has soaked through a fair way into the pads, I'd never trust them again.

WD40 can have it's uses. It's ok at cleaning out derailers I find.

You can try to cook your brake pads to remove the contaminant from them. I tried this. It didn't work well. Just get new ones and watch out for the wd40. Did the same thing myself when using wd40 to clean the chain. Best to remove the wheels completely when spraying any lube crap near the bike.

Also stops door hinges from squeaking.

I actually LOL:D:D

I shouldnt coz its prob only luck that I've never done it and it could have been pretty dangrous. Imagine if you were in an accident, explane that one:D

Use an oil remover, strong detergent should do the trick and yeah prob chuck the pads....

Class:), funnist bit is that it took until the next day to realise it... which ment that when finishing up you looked at the disks and thought, ahh look at them, all oiled and slippy out, dont they look lovely:D

What's the saying?

If it moves and it shouldn't use Duct Tape, if it doesn't and it should use WD40...

Or I generalised it to "WD40 : the cause of, and solution to all maintenance problems"

Water
Displacement
40 it took the scientest/engineer 40 times to get the right balance of 'ingredients'

IT IS NOT A LUBRICANT.
It will loosen lighty rusted nuts-bolts-parts and teeth if you use it on your brakes.

Thanksa lot for all those replys peeps.

I knew I was going to end up buying new brake pads but I was just hoping someone would have a macgyver way of sorting the problem to save me thirty quid.

Cheers.
