    So I made a fairly bonehead move when oiling my chain recently. I have had a shaft drive, VF700C magna for too many years and forgot all my chain maintenence knowledge. Baiscally, I over-oiled the chain way too much and when I rode it after that, chain oil got everywhere, including, I beleive on my rear brake disc and/or pads. Since then, I have noticed that the rear brake effectiveness is greatly reduced.

    My question: should I attempt to clean the discs, clean the pads, replace the pads, or do nothing and just wait for the oil to wear off. If cleaning them is recommended, what should I use?

    Any and all help/comments would be most appreciated.

    Thanks

    Hootch

    Wow, you must have sprayed a ton on there. What type of chain lube did you use? I am fairly liberal with my chain lube, never extremely careful, and have never ran into this issue before.

    Use isopropyl alcohol to remove the unwanted grime from your rotors, if you want to be really safe, however I am sure you could just wipe with Honda polish also, and be all good. That stuff is amazing.

    In relation to the pads, depends on how much you got on them. If its just a light spray, it will burn off, however if its soaked into the pad, then you might have to throw them in the garbage.

    I ride downhill mountain bikes, which use a similar brake setup, just not as beefy, and can usually get away with burning the pads off, if I sprayed something on there. Just really depends what the substance is. If it was brake fluid, you would have to toss the pads.

    I am not an expert on the matter though. See what some other folks say.

    Yep...I soaked them. I used "Maxima Synthetic Chain Guard Crystal Clear" oil. I reckon I shouldn't have shaken the can first as it sprayed out real "foamy". It said to rotate the wheel slowly and spray on 3 different places...so I probably ended up spraying 3 times too much. It was dripping by the time I was done. Thought I had the excess cleaned up OK, but was wrong.

    I agree...that Honda polish is great.

    Thanks for the help.

    Do not attempt to clean it with slick 50.

    Yeah, make sure you use isopropyl alcohol on the rotor, and not rubbing alcohol. On the pads I would take them off, and block sand them. If the oil caused them to glaze over, that is the only way that you might be able to salvage them. Oh, and I would also give the rotor a quick scuff with sandpaper as well, just to help the pads bed in again after you block sand them.

    Replace the pads, they are toast. Remove the rear wheel and use brake parts cleaner to remove the film from the discs. Spray it on a clean, light colored, rag or towel and scrub thoroughly, continue to use the parts cleaner until you can no longer see any residue on the rag or towel. You might have to use a couple rags or towels. After the disc is clean, wipe with a dry rag or towel, checking to insure that no residue is left. While you are at it, use the brake parts cleaner to completely clean the caliper before installing new pads.

    +1 on replacing the pads, I am certain that they are done for.

    In addition, it takes all of 10 minutes to change them, and they are REALLY cheap. Good insurance.

    Thank you all for the the great advice. I think I will go ahead and replace the pads...for peace of mind and safety factors, it seems to be the best solution. I did clean the disc with brake cleaner, and it did not seem to help a whole lot...at least the brake still does not seem to grab as well as it did before, so that tells me to change the pads. I ride with my 8 year old son on the back, and there is no cost/benefit ratio needed when considering his safety.

    Appreciate it, folks!!
