WD40

[cashburning748r]

Great stuff until it gets on your brake discs.

Any cures as i'm running out of patience trying to scrub it off in motion. Bit fed up as the bike has just come back from a service and it wasnt picked up along with a whole host of other missing work. I guess this is what happens when you have to find a new service provider when your local one closes.

Brakes are biggest prob so answers on a postcard... take them off and scrub them?

Ditch your pads, they'll have been soaked in it by now and your biggest problem.

For the disks, I'd try cellulose thinners / acetone / tar remover, then finish with some fine steel wool.

but change the pads at the same time.

[chris_of_1979]

I'd think about taking them off, wipe them thouroughly with a CLEAN rag soaked in white spirit, then leave to dry/evaporate. Then wash off with plenty of water and leave to dry again.

Then re-fit them making sure new pads go in at the same time (the old one's will be contaminated).

Others might have a better idea though???

You've naffed up your pads CB, as Mr S pointed out they will have soaked up the oil, however if they are sintered pads, the oil may not have penetrated the pad material very far so you could remove the top layer and get down to fresh pad material.

I did this when my Ohlins blew a seal and sprayed fork oil all over the discs and calipers, nearly crashed, but that's another story. The pads were well soaked so I put them in the milling machine at work and skimmed about a mm off the top surface. Did the trick.

If you can be without your pads for a week or so, drop me a U2U and you can send them up and I'll skim em for you. Unfortunately this won;t now be till we get back after xmas hols tho'

Brake cleaner (inhibited trichlorethelyn) will clean the discs.

been there... dun that...

as said, new pads and clean the discs. Just a wipe with some brake cleaner was enough.

[rockhopper]

The actual lubricant in WD40 is very light so if the pads are ruined they must have used a huge amount of it!

Use meths or brake cleaner to clean the disks.

[Simon Reed]

Do not use white spirit as thats oil based !!! brake/carb cleaner is the only answer,but if i were you m8,i'd put new ones in,it ain't worth the risk is it ???

:puzzled:

Guys, thanks for the responses.

Special thanks to Yeti for the kind offer of a skim but I think im going to plum for new pads.

It's my own fault, after a good day out I chose to coat the bike in the stuff opposed to leaving it all night, sadly, i did this in the dark which restricted accuracy somewhat.

It wouldnt be a 'cashburning748' if I wasnt spending money on it... damn.

Any ideas for a mail order service? or flexible openig hours over xmas.

Seasons greetings, take care all.

CBR,

Brake cleaner will do the job. Like others have said unless you have soaked the pads in WD40 don't worry too much

I have got a bit of WD on brakes before and I'm still alive.

WD40 or similar in small amounts will soon burn off as the the majority of the liquid will evaporate.

Just take it very easy and see how the brakes are before nailing them outbraking the Novas into your local roundabout!!

I see a number of posts about WD40 ruining Ohlins. I assume this is the oil doing the seal in bit??? Or is there someting in WD that attacks the finish that I don't know about (yet)

TIA, Rob

As everyone says, brake cleaner from Halfords, clean cloth and that'll be job done on the discs. I've done it before brake fliud and WD40 and it really depends on how much the it has penetrated the pad and how long it's been in contact, but without seeing them, I'd guess a good spay with cleaner and gentle rud with some wet'n'dry paper until they're clean and dry and the pads will be fine, just take it easy when testing it out.

Brake cleaner will clean the discs. No problem.
I'm open tomorrow 9-30 till 12. If you have 2 pin calipers, I think I've got some Bendix pads in stock. You won't get them before Xmas, but early next week should be a possibility ;)

[cashburning748r]

Cheers chaps

Tomorrow, trip to Halfords for some brake cleaner, Mrs CBR will be busy fussing so i should be able to get away with it.

Nelly, I have a 748r O1, without looking im not sure how many pins, will give you a call tomorrow morning, even if the brake cleaner works im going to replace them anyway.

If you gonna replace them anyway, send me the old one's and I'll skim em for you for spares. I'll be able to tell as soon as I take the top layer off if they completely f****d or just slightly moist......

[nelly]

Mark, I'm sure you'll be on the 2 pin calipers on a '01 bike.
Take a look at the calipers and they'll be two pins holding the pads in, not one as on the early bikes.
chat tomorrow.

Thats an offer I simply can't refuse!

Thank you very much indeed, please send/u2u me your address and I will take you up on this very kind offer.

Will stick postage in with them along with a slice of Mrs CBRS home made xmas cake!

best wishes

U have U2U :sing::sing:

[rcgbob44]

Use Isopropyl alchohol as this does not leave any residue at all or meths.

[cashburning748r]

All sorted.

My brakes have four pads per side (L+R) and they came out real easy,

Pads looked ok and I proceeded to remove the top clogged layer with a file (mrs cbr's home made christmas cake also works) leaving a clean surface on each pad. (Uneven wear on the left side so need to overhaul at some point).

A little copper slip on the back and back in.

Brake cleaner on the disks themselves followed by a light rub with low grade wet and dry.

30 minutes later - as good as new, just as well as I couldnt wait to get out in this loverly weather!

Will do the 'back' later! - thanks to all for help. Happy new year.

Use Trychlorathane it's great for removing oil residue

[Scotty Monster]

i heard that the like's of halfords break cleaner was 'designed' for cars to stop the breaks squeeling (a sign of a clean discs and pads(if not missaligned)) and as such left a waxey residue behind, you should as rcgbob44 says use ipa
