Disc Brake Science - Braking Point
|
Pedal ratio, or mechanical leverage, is the ratio calculated from the length from the pivot point of the pedal to the center of the brake pedal (A), divided by the length from the pivot point to the master cylinder pushrod (B). Mechanical leverage is simply a means of increasing the brake force without increasing your leg effort. As "A" gets longer and "B" gets shorter, the mechanical leverage increases brake force without pushing harder on the pedal. The disadvantage is that the pedal stroke also increases, requiring you to push the pedal further. "P" represents the pivot point and "F" is the force, or push. With a 1-inch master cylinder stroke, a 100-pound push on the pedal, and the pedal having a 4:1 ratio, the force is 4 x 100, or 400 pounds, and the stroke is 4 x 1, or 4 inches. If you are not sure what ratio is best for your application, then a 6:1 ratio is a great starting point. View Related Article
