If you have ever checked into what replacing the brakes entails, you know the last thing you want to do is start the ball rolling on that adventure. In addition the operation of the parking brake is lacking as evident as the number of posts complaining of same. First up is my method of never moving the machine with the parking brake on, this is how I did it.
This is the switch that turns on the parking brake light on the dash.
The other side of the switch that now has the brown wires on it is in the normally closed with the parking brake in the off position. What I did was to tie into the seat switch wire, the signal side ( not the hot wire ). As you know getting off the seat with the machine in gear will kill the motor. Now with this switch in the circuit, if you put the machine in gear with the parking brake on, it will kill the motor. It caused me a few laughs today as I restarted the tractor, and it could become a pain in the butt, but frying the parking brake is now a thing of the past.
This is the harness opened up to get at the seat switch wire.
After I checked that it worked as intended I soldiered the connections and closed up the convoluted tubing. Jumping the wires together at the switch will take the parking brake out of the seat switch circuit.
As for the parking brake, someone needs an award for this.
My land is more hills than flat so when my parking brake got to the point where is wasn't as good as it was, now was the time to tear into it. The instructions tend to make you think of a rocket launch vs a brake adjustment. What they intend to happen is that as you press on the brake pedal the first thing that occurs in the differential lock is engaged, then the brake comes into play allowing both wheels to brake. Now what the intend for the parking brake to do doesn't necessarily happen. On the brake rod near where the adjustments are made there is a spring in a guide and a roll pin through the brake rod. When the parking brake is set there should be an opening between the spring guide and the roll pin as when the brake pedal is pressed to the max. The problem now becomes as you set the parking brake, the brake mechanism is allowed to relax and you no longer have max pressure on the brake mechanism. There is no way I can see to adjust the parking brake to hold the brake in max effort. Any ideas?
