Update: My Bobcat dealer showed me that my control valve is on a separate block, which is why I couldn't find the solenoid. After locating the solenoid, I had to hammer and chisel the old one off, clean up the stem with emery cloth, put the new one on, it's now happy! The brake solenoid, I believe, is shot so......once again, my Bobcat dealer told me that if one chooses not to replace that solenoid, they simply remove the wedge that's in there and sure enough. Next trip to my dealer will be to pick up the brake solenoid and that wedge. Thank you everyone for your support.
