When to change brake discs
Okay so after about 1 year of racing and training hard on my rig the brakes don't seem to grab properly anymore. When braking with the front brake as hard as i can, even with two fingers, I can't even lift the back wheel off the ground when shifting my weight violently forward. We're talking xtr race brakes on a 21 lb (9,6 kg) scott scale. I've replaced my brake pads multiple times and cleaned the rotors with disc brake cleaner after every ride for a week. Ischanging the rotors and pads the only solution? I've also tried filing the rotors with rough sandpaper.
