i just purchased a 97 avenger , has 4 wheel disc, i have replaced the rotors, calipers, brake pads and master cylinder. after bench bleeding the master cylinder and the brakes it still has a soft pedal. also the antilock brake lights is going on and off occasionally. is this a possible problem with the abs system? im stuck here, have had someone tell me that i has to cross bleed the brakes and after doing that the problem is the same.
