jeeaholic, i have still not finalise to change the brake system, yes looking for different options.
unimog421 has drum brakes powered by master brake cylender independent from engine (thats good because i can use brakes on slopes with engine off).
sir brakes are very hard, i have 2 options: 1- join gym again and workout on my thighs
2-install servo with boster driven by generator (thats bad because brakes will not work on slopes with engine off).
purpose of restoring mog is purely offroading, what do you suggest option 1 or 2 or something else?
