2015 Cat 236D Skid Steer

I was delivered my Cat Skid Steer this week upgrading from a 2000 Scat Trak. I haven't brought it to the job site yet have been driving it around the farm trying to get the feel of it. I have an issue that I need help with. When I stop/brake the skid doesn't stop it continues forward some then stops. I don't have a manual at this time the dealer is mailing me one. Any thoughts.
