Another post inspired this question. I’ve had some luck with vacuum bleeders, but not a lot. I like to use them to pull as much fluid and air out as I can before bothering my wife to help. My cheap vacuum needs replaced. I am looking at a mighty vac for about $50. The documentation says it has adapt…

They sell many types of vacuum pumps, I have a Mityvac MV6830. The brake bleeder adapters that came with this unit are just 90 degree rubber boots that slip over the bleeder screw nipple.

Harbor Freight (among other vendors) has a version where you hook your own air compressor up to the gadget and that somehow creates the vacuum to pull the brake fluid out. Guessing they use the Bernoulli effect, the air flow from the compressor creates the vacuum. No need to pull on that trigger o…

No one seems to believe me but I will again recommend attaching a snug fitting piece of rubber hose 4" + to a bleeder and pointing upward with the bleeder just loose enough that it will flow, then while paying close enough attention to the reservoir that it never runs empty pump the brake pedal unti…

your method works great if system has no air, otherwise some “persuasion” is still needed

I used this one: [image] Brake Bleeder and Vacuum Pump Kit This brake bleeder tool and vacuum pump kit makes it easy to perform brake service on your own. The brake bleeder kit includes an accurate gauge for testing and servicing many different pressurized systems on your vehicle. Easily…

I use a method similar to Rod Knox but use longer tubing to a jar mounted above the bleeder and I put enough fluid in the jar to cover the end of the tubing. this takes slightly longer than Rod Knox’s method but not if you count the time cleaning up the brake fluid.

[image] George_San_Jose1: Suggest to check that version out to see what sort of adapters it comes with. I have that one. Has pretty much any adapter you need for the m/c bottle. Works very well, actually, and surprisingly for Harbor Freight, has lasted me something like 15 years.

Harbor freight scared me, but maybe I’ll check it out today. I’m going right by there later.

I found it was enough to dab a little bit of petroleum jelly on the bleeder threads (externally, no need to unscrew it) to make it seal enough for a $15 Harbor Freight manual vacuum pump to do its job with no external help altogether.
