Macleesh Posted July 12, 2023 Report Share Posted July 12, 2023 To assist in tracking down my misfire I think it's time to add a vacuum tester to my toolbox. Looking on Amazon most seem to be combined with a hand pump for brake bleeding, that would probably be a useful addition but I'm not sure if they display the level of vacuum exerted by an external source. What's everyone using? Thanks Sean Quote Link to post Share on other sites
BlueTR3A-5EKT Posted July 12, 2023 Report Share Posted July 12, 2023 I have used a MityVac hand pump for years. For both applying a vacuum to test leaks and capsule operation and as a brake bleeder. The tool has a dial with a vacuum scale on it. https://cartoolstore.co.uk/manufacturers/mityvac/mityvac-mv8000-automotive-tune-up-and-brake-bleeding-kit-mv8000 Quote Link to post Share on other sites
Ransomes256 Posted July 12, 2023 Report Share Posted July 12, 2023 +1 for Mityvac. There are plastic bodied and more robust die cast versions. Neil Quote Link to post Share on other sites

JohnC Posted July 14, 2023 Report Share Posted July 14, 2023 (edited) Just get a regular vacuum gauge, like this one (this is an Australian supplier, but they're pretty generic). There are also more sensitive ones, but I assume you only need to measure around the 10"Hg range. I have a 0-100kPa and a 0-15kPa connected in parallel for my PI calibration rig. If you need to generate a vacuum it's very simple if you have a compressor - just connect the airline to a vacuum generator (a venturi with an adjustable flow rate). No need to pump, and the vacuum stays nice and stable. Ish. John C Edited July 14, 2023 by JohnC Quote Link to post Share on other sites

Note I've never had much time for vacuum brake bleeders- unless you are really careful they will suck air in around the bleed nipple. Quote Link to post Share on other sites
Macleesh Posted July 14, 2023 Author Report Share Posted July 14, 2023 Good idea re the compressor, forgot I have that capability, although I don't use it for brake bleeding, I prefer my Eezibleed. Thanks Sean Quote Link to post Share on other sites

Agreed. I love my Ezibleed. I use the compressor/vacuum generator when calibrating the PI. Quote Link to post Share on other sites
