Anyone know how I can check or fix this? | | | | | Joined: Apr 2005 Posts: 1,107 'Bolter | | 'Bolter Joined: Apr 2005 Posts: 1,107 | put your foot on the brake pedal then start truck. if brake pedal drops slightly then most likely its working. disconnect the steel vacuum line from the unit(line coming from engine) if you get brake fluid running out then some of the seals are leaking and the unit is on borrowed time. if you havent post a pic of the unit. | | | | | Joined: Sep 2013 Posts: 20 New Guy | | New Guy Joined: Sep 2013 Posts: 20 | Ok, thats what it does.
