If the Race lever pushes less fluid than the Tech, how can it be more ‘powerful’? I can’t work that out.
Surely how far the pad moves is a function of how much fluid is pushed into the calliper (assuming the lever is the only variable in the system)? Or does the physics change once the pad is in contact with the rotor and therefore not moving, but applying pressure?
The larger the ratio of distance the finger pulls the lever to the distance the piston pushes the pad, the greater the mechanical advantage. Same with the brake pedal in a car with unservoed brakes, the further you have to push it, the stronger the brakes if all else is equal.
