Posted on 14th, August 2008 about 4 Pack Organic Disc Brake Pads
I've had the Shimano M525s, the standard compound ones (S2). They stop quickly and wear out about the same rate as shimano ones under normal conditions, maybe a bit better. Do check them when they get down 1.5mm because I blasted through 1mm in one very wet, very gritty 20km ride. When they got down to below 1mm, the remaining pad came off the backing plate. I can't complain, I should have put fresh pads on before I started the ride! Basically they're not the "best" pad out there but they are good VFM.
