alot of fun i must say but they are slowly killing my scooter bushes are going back brake has gone spongy over night its making all sorts of noises . pulling my fuckin hair out feel like scrapping the bastard thing
if by spongy you mean the brake lever is coming further towards the bars, its probably a stretched cable, used to get it alot with my mountain bikes/bmx's, if its not that it could be the pads, they may have de-teriarated causing your caliper to pull closer to your disc, dunno about drums, never had a look at one.
Leaky seal doesn't help! Mines leaking too, if I clean up the shoes then they'll work fine for a few miles until they get oily again and gradually stop working completely
