Noobie here. Looking for info to adjust the brakes on an allis chalmers 620 (made by Simplicity) hydro with 3 ranges. Just freed the left right pedals to work independently and see some Braking but mainly stop just on the hydraulics. Parking brake is marginal at best. Needed the brakes badly when it popped out of gear on my hill. I'm hoping there is an external adjustment because the machine is running good and I don't want to get into the axle unit unless something breaks.
Thanks.
Thanks.
