Does anybody have comments on the special bleeders which let one person bleed the brakes? Do they work well? Are they available in various threads or only one or two?

I have new Willwood calipers on my Cobra which have four bleeders per. Only the two highest will need bleeding if I understand correctly.

if you have extra same fluid your using,connecting a rubber hose buried in a bottle of fluid,so you can see bubbles the fluid won't let air back in your system.

Yes I've been using one and it's great.

I have the one where you put a fitting on a reservoir and you pressurize the bleeder canister with a hand pump.

It works fast and saves your master cylinder from all that foot pumping.

Just make sure you depressurize it before you remove it.

I think Tom is referring to the "self bleeding" fittings that replace the normal fittings on the caliper.

If so my comment is that they did not work very well for me. My experience was they still let some air into the system.

It appears that cristuna is referring to a pressure bleeder. If so they work very well and that is the only method I use. Makes it a one-person job.

Bought a Motive Power Bleeder maybe 15 years ago and still pleased with it, works like a charm. Maybe five years ago I had to replace a clamp, the hose and the rubber seals, after it wasn't used for a couple of years. Makes the job easy peasy.

I've used them, with good results They're available in various thread patterns. All they are are bleed nipples with a smear of sealant around the threads and an internal valves.

I use the pressure bleeder. Been using it for years. Easy peasy nice and easy.

I have used the vacuum bleeder and the one with the special fitting and both worked fine. Just don't let the reservoir go dry.

I have a miti-vac which I have seldom used. Is there a kit with fittings to make this a pressure bleeder?

Believe a miti-vac is vacuum, you need pressure. The miti-vac pressure tester, with the right fittings, can be used to bleed brakes, but it's less convenient as a pressure bleeder.

The typical hand held Mity-Vac (or similar) can be used to vacuum bleed the brakes but it is a little more difficult since each caliper must be done individually by attaching the vac source to the bleed screw. I think it still offers opportunity for introduction of air around the threads of the bleed screw.

The pressure bleed is a no-fail easy method. As a bonus, it also ensures that both master cylinder chambers remain full, often a point of frustration when bleeding an ABS system.

I had a set of those bleeders on my Vette and they worked great. I have a master bleeder that I’ve used on most everything else for FLUSHING. Bleeding a system that has been opened up in multiple places is a different kettle of fish and often requires two people or one of the professional bleeders.
