Yeah these do suck. When I first had mine it was beyond dangerous.. but after finding and replacing: the peddle rod mis-adjusted, all the sliders seized, air in the system, replaces all pads with EBC-Xs and added chamfered edges and replaced the fluid with DOT4 synthetic, I can say at least they will stop it now...and lock-up all four..and with using only one foot...lol. Still..no where near as good as others like my friend's RzR. I still think the pressure ratios are incorrect.
