any one no if you can buy a Torque Sensor for a 2015 cf800

looking for a Torque Sensor for a 2015 cf800 800cc power steering system..

I have been getting a squeaking from the back brakes for a while now. I would only get it when bike was sitting for a while. It would go away after a ride. It seens now I have no foot brake. I checked pads and there are grate. I am getting a very small bit of compression on the piston, but no stopping power... Fueled is toped up. I bleed the brakes to see if air got in but still foot brake leave is soft.  Any one???

dont leave a 5lb hammer in it and go for a ride on a hard rocky bumpee traills.. smashed everything in it and cracker a hole in bottom.. lol  had to replace box.. $29 Wal-Mart

on two different rides,, the steering get very louse,, the problem is the part that connects to the shaft right under the power steering drops off the gearing. if not for the plat under it, it would fall of.. I loosened the boult and put it back in place.. but it happened again.. has anyone had this trouble and best was to fix... 
thanks

i have a 2015 cfource 800
