Hi All, I recently got a 1991 753 Bobcat. Going over the machine. It has the manual parking brake. O&M manual says to adjust (the linkage adjustment nuts) for 3/4" play between heel of pedal and floor. I don't understand the instruction. To me, it sounds like they want 3/4" slop in pedal movement before the spring on the brake linkage starts to be tensioned. The spring on the brake linkage holds tension on the pedal and is further tensioned as you set the brake. Without any tension, that spring would simply unhook and fall off. So I'm not sure what the manual refers to when it says adjust the adjustment nuts for 3/4" of play at the heel of the pedal. Anyone familiar with proper brake adjustment on this vintage 753 machine? Thanks, Dale
