Just got a new roof rack with a fork mount. I've been warned on the dangers of activating my Hydraulic Discs with the rotor removed. I'm concerned about inadvertent pressing of the brake lever, either by me or accidentally by others.
How best to combat this? I've heard there are shims that can be placed in the calipers. Are these worth trying? Will they stay in while the bike is on the rack and transporting? If so, where can I acquire these?
Any other alternatives?
