First and foremost,
Pads are not available anymore. You have to re-line the old.
Here are a couple "how to" threads:

If you are trying to use the brake/clutch when going downhill, you need to stop. This is a tractor, not a car. Use a lower gear when going down hill. If the tires are sliding, brakes wont' help anyway. You need more aggressive tires (ags) and weight (wheel weights/fluid filled tires) to hold the rear end to the ground. Pressing on the clutch and hoping that the brake will slow you down on decent is a bad idea, and crash waiting to happen. Please, listen to this advice before you get hurt. But do fix the brakes. A gear drive without brakes is bad news.
