My pacbrake has been installed for about 4 weeks now and I enjoy it very much. I was able to do it all myself. I just have one question about it though. When the brake is actually working are you supposed to be able to hear the brake itself running? I can hear air pressure at the brake itself when it is on. Is the elbow supposed to go in exactly as the stock factory one comes out? I was not able to get the pacbrake elbow to line up exactly as the factory one came out. The V-clamps seem to work on the turbo outlet side but when I went to put the second one on the elbow was a little off. Have any of you had this problem? And if so what are my options. ? I have yet to check for an exhaust leak around the clamps as I am busy working.
