i just got my truck back on the road after about a year of setting its a 97jimmy. the pedel is spongy and they need to be bleed but the major problem is that sometimes it will stop just fine but other times the pedel is rock hard and wont move no matter how hard you push not like a bad brake booster it just wont move at all what could cause this? maybe the abs or port valve idk
