Hi to all the tech experts.... 

Can someone please advise what this "grubscrew" (see pic attached) is for or what it does?? 

I can't find anything on this and / or the function of it....

Any help will be appreciated

It does "free stroke adjustment". If it's anything like their MTB brakes that basically means it does f*ckall.

But theoretically it adjusts how long the lever pull is until you reach the bite point.

Hi J. Nope. I'm fimiliar with the  free stroke and "lever reach" adjustment. This is an additional grub screw on top of the lever. 

See image attached.... 

Tx a mil though and please help me figure this out😊
