Parking brake for your Polaris PRO SERIES - Fits all PRO XP, PRO R, S and TURBO R models.
This brake allows for a pad-lock to be inserted through pre-machined holes to give you the added option to use as a theft deterrent.  
Installation is simple and quick
Back out the 15mm nuts on the master cylinder behind the brake pedal.
Put on the Spring Brake Thingy.
Then put the nuts back on.
It is that simple and quick, takes no more than 2-3 minutes.
To operate, depress brake pedal with right foot, slide lever over brake pedal arm with your left foot and the SBT engages all 4 brakes.  Once set, add your own pad lock (1/4" to 5/16" shaft) for that extra security.  To release simply unlock pad lock, remove, and depress brake pedal.   
 ALWAYS USE PARK WITH THE SPRING BRAKE THINGY AND MAKE SURE YOUR BRAKES ARE IN GOOD WORKING CONDITION.
