I recently bought a 2003 bobcat 863 Turbo It ran fine for the first hour or so, then out of no where the parking brake engaged and I was stuck no matter what I tried it would not release the parking brake. I let the machine cool down tried again and was able to move it, I started using it again for about an hour then it did it to me again and this time I could get it to disengage for a second then it would engage again, I've replaced the battery Checked the switch but I'm not really familiar with these machines I'm getting 14.2 Volts out of the alternator the Hydraulic fluid it full so I'm not really sure what the problem is any ideas?
