been wondering about reg brake pads such as you have
will cutting groves in pads help with the stopping ???
ride that thing Mountainman
wow, something I can answer. cutting the pads themselves wont do any good and at best will crack the graphite compound usually embedded in disc pads.
you'd want to cut grooves into your rim itself or for disc brake rotors....just use the stock ones with holes. grooves are mainly to remove dust as it forms to help maintain a good grip on the other surface without gas buildup.
sorry, I just have been into scca racing for the past 10 years. just not familiar with bike terminology/behavior yet
