i've done something a bit silly to my rear brake - SV650.org

31-07-06, 09:45 AM

when i was cleaning the chain/surrounding area yesterday, i thought i got some crap on the disk/pad as i took it out and the brake didn't seem as effective - v. slow speed it stops the bike but basically feels like there's a fluid leak, when at slightly higher speed it just takes ages to slow!

so i thought i'd better try and degrease the rear brake, and oh what can you use for degreasing that i have near me...hmmm, a can of wd 40

which although i dried it off and it didn't feel greasy, i've since realised it's a water repellant and probably is oily

so i need to clean the brake (again) - and a biker here suggested i burn it off by riding along with the brake on (not as if it does anything at the moment!) - i thought i'd try this on the way home tonight (about 40 mins of town riding) and then if it hadn't fixed itself, go to the shop and get some actual degreaser and try that on the disk. i *really* don't want to have to take the caliper off to clean under there...

does this approach to cleaning it sound like a good idea?? or is there anything better i can do?

I would personally either give the whole area a good scrucb with a bike cleaner & degreaser such as Muc-off or similar, or use some brake cleaner. I wouldn't want to ride for a long time with the brake on.

Petrol works well, from experience. Riding with the brake on does work, but apparently it's the quickest way to get the contaminants properly into the brake pads.

Aerosol brake cleaner, the clue is in the title.

Mabey the pads have been shagged because of the WD40 and need replacement.

Me - I'd clean the disc and replace the pads, EBC green stuff are probably about £12. IMHO you don't need sintered pads on the back

thanks guys, i will probably get some brake cleaner on the way home and clean it up. i'm not sure i'll replace the pads until i've seen how it feels, because i don't want to have to take anything off just yet... (due to time). i'll let you know how it goes!

Personally I'll just use brake cleaner or bike cleaner as mentioned. Depends on how much you use the rear brake I guess. Getting new pads for me would be a waste as I rarely use the back brake now.

Cheers

Remove the rear caliper. Fit new pads.

It isn't difficult and if you get stuck you can always ask for advice in here.

cheers, it's not the difficulty (or lack of it) that's the problem, it's the time/effort lol - i've played about on cars quite a bit so i don't think it will be too difficult to do.

if the brake works ok for me after cleaning it, i don't think there'll be any other effects i should worry about...right?
