you see ducky the big problem i have with hydrolics is when fitted to front of the car you loose your hand brake turns as i will call them,when all four corners are braking together.
also four wheel hydro makes for tricky handling and tricky braking.they are powerfull like,the reason i state this is a friend had them on his mcd and he used flip the car a lot.
u know when you have rear brakes alone its very handy too to be able to swing the arse of the car around when rear brakes are locked.
,with hydro fitted to front its a totally differnt ball game,differnt braking,in my opinion the hydro set up is more suited for track use for intense braking.
otherwise offroad like ours(my opinion) a set of discs atthe rear is more than enough. or your set of hydros at JUST the rear would be good.
im iffy about hydros on all four corners. (not cutting them,my opinion)
