hi, i just bought a 90 accord LX as is (5), but the breaks are awful. i bought fresh pads and calipers, installed them but the breaks are still not operable. i took the tires off and it turns out the pads aren’t even hitting the rotor when the break pedal is pressed. my father suspected something with the pistons, but we exchanged the old parts for new ones so that wouldn’t make sense. whats wrong? we tried bleeding them in the order the hayes repair manual stated, but nothing.
