[quote=”spelunkerd” post=33635]Occasionally I think about doing this. But then what goes through my mind is the question as to whether the cap on the MC is the same size with all vehicles. Is it?
If they are different sizes, you would need a set of adapter caps to make the pressure device fit on top. By the time you make a whole set of caps, you could have bled the brakes normally with a friend pumping.
I do have a vacuum bleeding device, but it seems to regularly find a leak at the hose connection, so I rarely use it.[/quote]
Unfortunately…they are. I have a ‘professional’ unit and had to buy a drawer full of adapters only to find sometimes I still don’t have the right one to do the job :angry:
As for using the vacuum bleeder, I too have found they seem to show bubbles in the fluid being pulled out of the caliper/cylinder, but what’s really happening is it’s sucking air down through the bleeder’s threads. That doesn’t mean air is getting in the system, just a bit annoying to gauge if it’s air in the system or not. Applying dab of grease or anti-seize on the treads helps.
