Rusty Brake Discs!!

Post by **Zax** » Wed Mar 03, 2004 11:31 pm

I will use a spot of WD40 for cleaning my wheels asit is great for getting rid of any greasy marks.

However i did once get a splash on my disk ..... NIGHTMARE.. it was ages before the brakes were anywhere near as good as before.
That was just an accidental drip of the stuff that was wiped off quickly .

Joan, Scotchbrite is basically an industrial strength scouring pad :) I think I may have some at home if you need..need to have a look through my old gun cleaning stuff. Failing that, I have seen it in B&Q..a few quid for a pad. Just run the pad the same way as the disk turns. Rust comes of pretty quick. Check to see if the pads have rusted to the discs though..may have left a noticable "bump" where they may have bonded...

As for chain and sprokets..Busters are doing cheap o and x ring chains, but if you go for them, be careful as they are not the best quality. I personnaly think you are better off getting a decent chain having witnessed two broken chains on mates bikes. It leaves a right mess as the broken end whips round and takes the rear of the sump with it!

I had a gold X-ring D.I.D. chain with Renthal sprokets on mine. I think the kit is about Ã‚Â£120. If you go for an OE plain O ring and sprokets from DID I think its about Ã‚Â£89. I got mine from Breaking Point although mail order can be cheaper.

Good time to change your gearing by the way!! Get a sproket with one tooth less on the front

Have fun!

i always spray the discs with wd40 to protect them when the bike is sitting for a while.... and yes when you pull away expect to have sod all breaking for a time but it does go away... though the rear brake takes a lot longer given it doesn't do so much work.

be warned about rust on discs, my puegeot 206 was sitting for about a month, when i took it out i was getting severe pulsing through the brake pedal, this was due to the pads corroding in some areas and not in other so you experience a cycle of good and bad breaking as the disc rotates, if you are able to get the discs off and want them skimmed or even polished on a lathe i have a mate in a work shop that could do it for you, no charge

if u r a student now i take it u aren't in shell anymore?

cheers

Doesn't the WD40 get absorbed into the sintered pads? I would imagine that full braking performance may never return.

maybe it does though i haven't noticed anything significant... i'll tell u in april when the bike comes out of hibernation... it should have absorbed about a gallon of WD by that time.

incidentally a vry very good cleaning fluid i got from a guy that deals with offshore stuff is something called jizer, it's water soluble unlike wd so once it disolves grime etc (and it really takes grease / oil etc off fast) you can just wash it away without dissolving your tarmac'd drive like i did with excess wd..

Well just been out on my bike and rust has come off a wee bit from the discs but no more than usual. Had a good look at them and i need new ones anyway cos they're all grooved!

I've sprayed wd40 on my chain, take it thats ok?

Rustik, i quit Shell back in September to go back to college full time!!

Nooooooooooooooo...WD40 on the chain is not good!... Clean it off and get some proper chain lube (I can't believe it's not butter!), or nip round and you cna borrow some of ours..

Jinx · Post by **Jinx** » Mon Mar 08, 2004 10:47 am

Whoops, well it got me to my work ok this morning!!

I've got chain lube (I can't believe it's not butter!), just thought wd40 would be good for the rust on the chain!!

There are several theories that it buggers your chain..from it being a penetrating oil, so it forces out the oil in the rollers....too it eating the o-rings themselves. I really don't know, but certainly every bike mag says not to use it :)

At the end of the day WD-40 is not designed as a lubricant and therefore shouldn't be used as such

Yeah, but what if you work nights, the end of your day it's light

There is no light and dark......only shades of grey

Being roughly on the same longitude as the UK the time difference isn't that great, plus or minus an hour I think.

Maybe a new career beckons - offshore surveyor perhaps?

Actually....Yes. Nothing to do with the time diference (2 hrs), but a 12 hour flight and a 3 hour stop in Paris with an 18 month kid!

How about trying some of that Scott anticorosion stuff. It's apparently water based (although it does contain a slight amount of oil) and washes off with water. It does say on the bottle to avoid getting it on the brakes, but if you do to wash off with water.

It'd certainly be better than WD40 and a better corrosion resistor too. I seem to remember a test on this froum with some rusty washers or something and the Scott stuff came out well on top.

Still wouldn't put it on my discs, but if you want to it's up to you. I have a heated, de-humidified garage anyway

rustik · Post by **rustik** » Wed Mar 10, 2004 11:11 pm

as soon as my can of WD40 is finished I'll be getting some of that scott oiler stuff... Big Kneed Al (master of the emergency stop & "stand up" comedian) mentioned it on the phone tonight...

my draughty, unheated, small shed just don't cut it! at least it's dry i guess

Gingerpose · Post by **Gingerpose** » Wed Mar 10, 2004 11:49 pm

how about the old trick of soaking the disc in coke? the acid content is enough to remove the rust but won't weaken the disc itself. Does mean removing the disc (and believe me I know what a bitch of a job that can be) but it does work.

Post by al » Thu Mar 11, 2004 12:38 am

If you're going to use coke then I've head that there is a good supply in Peterhead!!!

As for the Scotoiler F365 Protector spray I've no complaints so far!!

For the first 2 lucky folk to buy a 5 litre refill from scotoiler I've got a couple of empty spray containers you can have!

I find a liberal coating of grease stops the discs from corroding and the pads last much longer.

Post by **Gazza** » Thu Mar 11, 2004 1:30 pm

One could always do away with the rusty old things altogether. Just think how much easier it would be to clean the wheels for a start.

In order to stop, just dig your heels into the road and hang on tightly to the handlebars (probably better than a greased disc!) :I can't believe it's not butter! :I can't believe it's not butter!

Why don't you get a drum brake conversion done on the bike??? No more horrible rust to look at!
