Sounds like you have a lazy piston, or a badly bled brake, Both pads should move the same amount at the same speed at the same time, Or there abouts.
---Oh, I didn't know that. Thanks. Will 'borrow' some Spray grease tomorrow from work and have a look.
As for your trackside fix, you might just end up ruining your brakes doing things like that, follow the video and set them up properly, Only takes 5 minutes and will make a world of difference in reducing slipping
---Which video?
And i know. But i was out riding. and i had no tools. And i was like 45 mins away from home in the car :/
