mod_biker_barney Posted August 1, 2012 Report Share Posted August 1, 2012 Does any one know the procedure for correctly cleaning and disinfecting hope rotors? I'm thinking mine is contaminated and don't want to use it just in case, help would be appreciated, thanks Quote Link to comment Share on other sites More sharing options...
Matthew62 Posted August 1, 2012 Report Share Posted August 1, 2012 A good clean with methylated spirits should do it. Really rub it in with a clean cloth/rag and it'll evaporate and won't leave any residue behind. Quote Link to comment Share on other sites More sharing options...
AndrewEH1 Posted August 1, 2012 Report Share Posted August 1, 2012 You might want to clean your pads at the same time as they could be contaminated as well. Quote Link to comment Share on other sites More sharing options...
Matthew62 Posted August 1, 2012 Report Share Posted August 1, 2012 Or should really just whack them in the bin. I know a guy who has just bought an abundance of miscellaneous hope parts so give me a shout if you need any replacements... Quote Link to comment Share on other sites More sharing options...

AndrewEH1 Posted August 1, 2012 Report Share Posted August 1, 2012 If you are just switching your rotor your pads will be fine. Just get some meths as Matt suggested and it should be fine! Quote Link to comment Share on other sites More sharing options...
bing Posted August 1, 2012 Report Share Posted August 1, 2012 for added cleanliness, soak it in brake cleaner and set it on fire, this will burn any shite off the disc surface. then get a peice of wet n dry, prob about 400 grit, put it on a flat surface and lightly rub the disk on it. helps the bedding in process Quote Link to comment Share on other sites More sharing options...
mod_biker_barney Posted August 1, 2012 Author Report Share Posted August 1, 2012 Cheers lads, so do you rate your opinion more then Bing? Where is brake cleaner available? And just tried to undo the bolts on my front avid rotor, onto a hope II hub, and they appear to be stuck, any tips on loosening them up? Thanks Quote Link to comment Share on other sites More sharing options...
bing Posted August 2, 2012 Report Share Posted August 2, 2012 get proper bike disk brake cleaner, not brake/clutch cleaner from a car shop. as for loosening the bolts, spray em with penetrating and release spray, and tap the bit in with a hammer. if they still won't release, GENTLY warm the disk flange on the hub up with a blow lamp, at the same time undoing the screws. the ally on the hub will expand faster than the steel bolt Quote Link to comment Share on other sites More sharing options...
mod_biker_barney Posted August 2, 2012 Author Report Share Posted August 2, 2012 Ah sweet I'll give it a shot! Yeh just cleaned it with a wire brush and boiling water earlier; but halfords have disc cleaner (although the description states use for motor bikes) would this still enable a thorough clean, allowing for the hope brake to fully grip the disc?

bing Posted August 2, 2012 Report Share Posted August 2, 2012 if your disk is contaminated, there's a fair chance the pads are too, just get a new set, for the cost they are its easier than trying to make them work. as for the Halfords stuff, never used it, so I wouldn't know. I got some off my mate who runs a bike shop Quote Link to comment Share on other sites More sharing options...
dezmtber Posted August 2, 2012 Report Share Posted August 2, 2012 the best stuff to use is isopropanol alcohol. you can get this from any car part shop, its labeled as electrical contact cleaner. it leaves no residue (oil) at all. ( meths car brake cleaner does have some oil in it) clean pads with the same stuff. and use some wet and dry on the pads too. to check if your pads are properly fubar put the wet and dry on a flat surface and gently rub the top surface of the pads on the wet and dry leave the pads a few minuites if you se the dry dusty surface go dark it indicates there is still some dampness in the pad material if you see this buy new pads they are fubar. finaly rub the disc with wet and dry on the braking surface to allow the disc to gring a the pad flat and even to the disc. if this all fails get the bike to a good bike shop.

mod_biker_barney Posted August 2, 2012 Author Report Share Posted August 2, 2012 Yeh the pads are brand new, hence why I wanted to make sure the rotor is clean, but cheers, I'll try that Quote Link to comment Share on other sites More sharing options...
onza pro series guy Posted August 2, 2012 Report Share Posted August 2, 2012 halfords have disc cleaner (although the description states use for motor bikes) go to the bike hut and there should be bicycle specific brake cleaner, it comes in a can.

bike_dummie Posted August 4, 2012 Report Share Posted August 4, 2012 Isopropanol alcohol is better in my experience as I've always found methylated spirits always leave a slight residue not much but some. What I normally do is I submerge the rotor is hydras sprint for about 5-8 hours (no longer or the sprint will eat away at your disc) taking it out every now and then to give it a good clean with a cleaning brush (medium) depending on how bad it is. After 5-8 hours thoroughly clean your rotor with running water as the hydras sprint will go like soap, again if you can brush scrub the rotor with a medium cleaning brush if you have more then one (don't use the same brush you used for the sprint earlier). Once you've thoroughly cleaned your rotor you will need to submerge your rotor in isopropanol alcohol for in my opinion 24hours making sure you have a lid over your container otherwise you will have none left by the morning as it will have all evaporated (flip the rotor over after 12hours). After 24hours take the rotor out of the isopropanal and just leave it on a clean surface for the alcohol to evaporate. 1 Quote Link to comment Share on other sites More sharing options...
Monkeymusmax Posted August 4, 2012 Report Share Posted August 4, 2012 i always use juice lubes brake cleaner from stif cycles its about 8 quid for a big can Quote Link to comment Share on other sites More sharing options...
knave Posted August 4, 2012 Report Share Posted August 4, 2012 How badly are the rotors messed up? With the utmost respect, I find some of the suggestions to be overkill if they aren't in really bad condition. I can understand worrying about contamination because I'm a worrier about that kind of thing but if you use any decent brake cleaner/white spirit and a tooth brush you'll be ok with the exception of only the worst cases. I've never gone farther than this and have never had a problem in years of use and abuse including one incident where chain lube gushed all over a rotor.

mod_biker_barney Posted August 6, 2012 Author Report Share Posted August 6, 2012 To be honest, it doesn't look too bad whatsoever I just wanted to de contaminate it just in case there was a chance... The dishwasher works?! Quote Link to comment Share on other sites More sharing options...
