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?

1Have you tried bigger rotors? What bike and terrain do you ride?– SwiftyCommented Aug 3, 2018 at 17:31

1Do you mean a fluid for 'washing' the disc pad and rotor, or the hydraulic fluid?– mattnzCommented Aug 4, 2018 at 3:37

Well trains have a pipe that drops sand in front of the wheels to increase friction. You can all head over to Kickstarter for my Iron Rooster Disc Friction Enhancer.– Henry CrunCommented Aug 5, 2018 at 7:41

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.

Mechanical or hydraulic brakes ?
If mechanical, maybe the cables are not tight enough ? or too used ? If hydraulic, maybe there's a leak in the system ?
In both cases, maybe the pads are too worn out ? maybe the brakes rotors themselves are dirty or worn out or have some oil/grease/dirt on them, clean them out.
Have a looksie at :
