This kit is intended to fix SLOW LEAKS in your older door lock actuators. It is NOT intended to repair leaks caused by cracks or tears in the rubber diaphragms!! Please CAREFULLY INSPECT ALL of the rubber on your leaking unit before ordering this kit.
If your early door lock actuators do not have any cracks in the rubber diaphragms, but they just won't hold vacuum - it may be possible to fix them by taking them apart and cleaning and resealing the outer lip of each diaphragm.
Old age hardened vacuum lines and hoses can sometimes be a real pain to remove. Then tend to just get "stuck" in place. Rough attempts to disconnect them can cause damage. If you are not careful you can crack the rubber hoses or break the plastic lines when moving or pulling on them.
This is the same guage that we include in two other kits. See related products below. We realize some may just want a simple vacuum gauge to have in their tool box for troubleshooting purposes. A gauge like this is a "must have" if you are having vacuum related problems on your older Mercedes.
