Every so often, my rear brake starts groaning at almost-stopped speed, and if I let it go too long, the brake gets grabby. When I take it apart, I find a bit of oil on the brake shoes (it doesn't take much to cause a problem). After cleaning everything with brake cleaner, it's ok again, for a while.
I assume that the oil is coming from the chain. I use the best chain lube I can find (Chainwax), but I use it often, and it just occurred to me as I'm writing this that I haven't been wiping the chain off after lubricating.
Anyway, I just wanted to know if any other A65 owners have experienced this problem.
