Disc brake performance fluid I own a mountain bike with mechanical disc brakes that seriously lack stopping power. I've tried tweaking things and replacing pads but always fell short on performance. I ride more on the road but sometimes offroad. I was just wondering: Does a fluid for making disc brakes "grab" better exist?
Not that I have ever heard of. Any liquid on the rotor or pad would tend to act as a lubricant and get worn or washed off anyway.
