MANUAL BRAKES anyone use them?

[GregWeld]

Measure your pivot point to the center of your brake pad (i.e., the length of the pedal)... and then from that pivot point to the Master cylinder push rod point.

Divide the longest length -- by the shorter length and that's your rod ratio. It needs to be 6 or 7 ---- if it's 4 that's a power brake ratio.

The brake pedal is a LEVER -- you need less leverage for power brakes than you do for manual brakes...

You want to be able to push 100 pounds with your leg and have that translate into 600 or 700 pounds of effort on the master cylinder.
