Push Toggle front ( Charlie Cuninghams 1st ever and most powerful brakedesign)

T.D. .. cable is anchored to the fork crown, so the housing pushes down on the center of the linkages, parting the upper ends of the brake arms. That pushes the lower end of the arms and pads toward the rim.

It's probably better in all regards in terms of those three performance metrics (better than the LL, CC´s last and best brake linkage ever made), but it's a royal pain to set up. For example the centering of the arms is adjusted by twisting the angle at which the cable is anchored to the fork crown. There is also not an easy way to adjust for pad wear like the Lever Link. There is also some concern that it could cam over and not return. Making these brakes by hand was a huge effort which Charlie described as "fiendish."
