2008 navistar 4300 medic unit. on brake application pulls left the harder you push the more it pulls. front and rear brakes were done on january 2018. everything normal up until monday. we have gone thru brake system and found no issues, the same with suspension. in january we replaced calipers, pads brake hoses and rotors front and rear. we just switched hoses, calipers and pads side to side and made no difference. i am thinking a problem with ehcu fluid feed to right front wheel may be restricted. i have brake pressure gauges and when hooking up to caliper found one of the gauges broken. crap!! any help or suggestions appreciated.
