Not neccessarily if you have a lot of air in the lines. Its easy to compress air and not feel any resistance. Be patient on the bleeding. Start at the fartherest bleeder. Have your help pump the pedal three times , hold it to the floor then you crack open the bleeder at the wheel cylinder and let out the air. While the helper is holding the pedal to the floor and air and fluid has quit coming out,close the bleeder and repeat the process until clear fluid comes out. Then move on to the next fartherest wheel cylinder from the master cylinder. Good luck!:bigthumbsup
