When you decrease the pedal ratio, you increase the stroke in the M/C. Power brakes systems use less pedal ratio, therefor more stroke at the MC for a given pedal travel.





Please explain to me how the mechanical ratio of the pedal is modified when you install a booster with no other changes.
A brake booster is a straight through design. It simply uses vacuum to help push the pedal and reduce your leg effort.



Where are the levers and other gizmos to change the mechanical advantage?
