Introducing the Evolution trans brake button (Evol-V1.  This button was developed to be smooth and accurate.  The all new stop design provides a simple travel adjustment as well as anti-rotation for the rod.  The chrome plated rod rides in an extra long linear bearing eliminating any play while providing an incredibly smooth feel.  Button return is driven by a single constant force spring. This spring allows for a constant feel as the return force does not change throughout the 3" of travel. The spring is also rated for 4000 cycles. All aluminum parts have been hard coat anodized. 

The button comes configured with one of two spring options. 

-Stiff Spring = .018 to .060 delay  (This is the standard option and best option when     additional delay is not needed

-Light Spring = .023 to .080 delay 

Two button head styles are also available, Smooth or Stepped.
