Ive tried rubbing the roters with rubbing alcohol, I took out the pads and cleaned them with rubbing alcohol and sandpaper too and got all the black stuff off them. They needed to be broken in again but they worked better. The thing is these brakes arent half as good as the V-Brakes on my 1997 bike. It's hard to do an endo with these disc brakes, they just don't grab and if they do grab it takes alot of hand power. I have the inner pad adjusted all the way out too towards the rotor which I heard was the proper setup, so the rotor dosent flex when the brakes are applied.
Please what tips and tricks do you have to make these brakes perform!
