Downeast Johnny Posted June 21, 2016 Report Share Posted June 21, 2016 I would try a salvage yard. Quote Link to comment Share on other sites More sharing options...
BC DOORMAN Posted June 21, 2016 Report Share Posted June 21, 2016 Remove that piece from your vacuum booster. It pulls right out and goes in the hydro booster. I had that same problem, luckily i caught it quickly lol Quote Link to comment Share on other sites More sharing options...
12secss e.mack Posted June 21, 2016 Author Report Share Posted June 21, 2016 (edited) The one from vacuum boost does not have the return spring plus its seems to be to long. [or don't need the spring] Edited June 21, 2016 by 12secss e.mack (see edit history) Quote Link to comment Share on other sites More sharing options...
BC DOORMAN Posted June 21, 2016 Report Share Posted June 21, 2016 Well I stand corrected, I will hit a salvage yard ( good buddy owns a large one buy my house) and split a hydro booster from the m.c. that could explain why my brakes would engage and not release. I replaced the hard lines, rubber hoses, front calipers and rotors (07' upgrade) and it is fine again. It worked fine for a thousand miles or so, then would randomly not release the brakes. The push rod seemed to be the correct length, but I was not aware of a return spring. Glad you mentioned it, I will let ya know what I find.

12secss e.mack Posted June 21, 2016 Author Report Share Posted June 21, 2016 Ok , get one for me to thanks Quote Link to comment Share on other sites More sharing options...
eberhama Posted June 21, 2016 Report Share Posted June 21, 2016 (edited) This is the vacuum on the left, and hydro on the right. Very different, and not interchangeable. Vacuum is actually shorter, but with the pointed end of the steel rod, they end up about the same.
