Break Boost Vacuum Analysis / Pic / Movie Posted by jeff02 [Email] (#2992) [Profile/Gallery] (more from jeff02) on Sat, 8 Jun 2013 16:48:58 Members do not see ads below this line. - Help Keep This Site Online - Signup |
Just replaced a break booster and it is behaving strange. Please find a photo and a movie what it is doing with a vacuum gauge analysis. You can see in the movie how it "multiple dumps" sometimes. So, do I still have a bad booster?
Test done at idle and tapped into just before the pressure switch with electric pump 99 I4 lpt.

Movie Shows one break looks good, another has the "hitches"
