That was/is a method for one man bleeding. Probably still at risk of sucking some air.
Dorman speed bleeders

The 1976 CJ-5 service manual says to open bleed screw, push pedal down, let up slowly, close bleed screw.
all that does is push fluid back and forth, without a checkvalve of some kind, you will never get a good bleed.
A buddy and a twelve pack still seem to me to be the best method. Modern mechanical contrivances that remove hops and barley from the process may work, but they suck the soul out of the procedure.
I modified my Motive Products Power Bleeder by teeing in an 1/8" tank valve:
Pros:
Input air introduced above the brake fluid, no aeration.
No more pumping!!
Cons:
Requires compressed air source.
Another port for potential contamination - don't want to be pumping wet, oily, dirty air into the tank.

I've used speed bleeders on motorcycles and the TJ with no issues. It is simply a one way valve that lets the pressurized brake fluid out of the bleeder valve, but does let anything back in after the pressure is released.
There are only 2 issues to watch for: running the reservoir out while pumping the pedal, and loosening the valve too much where it may draw air back through the threads (1/4 turn is normally sufficient to get decent outflow).

For my '06 TJ Rubicon, I am also looking for the speed bleeder valves. I see that Dorman makes one for the front brakes (ref Dorman p/n 12701). I don't see anything for the rear disc brake bleeder valves. Does anyone have a source for valves for the rear disc brakes. According to my Parts Manual, the front bleeders are OEM p/n J3203313 and the rear bleeders are 05179732AA (post 10/2005) or J0920463 (pre 10/2005).
instead of buying an expensive bleeder, buy a paint pot from harbor freight and convert it over to brake fluid with new hoses.

Old thread, I know. Has anyone been using the Dorman speed bleeders for a good length of time? I’m considering putting them on but am concerned about them being a failure point, especially just the Dormans.

Wasn’t sure if I’d be able to get them in Canada but looks like I could, $30 per 2pk.
Dormans are $10 cheaper for the 2pk and I can get them locally.
However I just came across this that might suit me well…

Same idea as the speed bleeders with the check valve but on a bottle, has good reviews too.
One thing I haven't seen mentioned is gravity bleeding. It's a good way to exchange your fluid for fresh and eliminate air. Takes a bit of time and babysitting so the master doesn't run dry. The TJ is so short though it doesn't take all that long. Use clear hoses and Gatorade bottles with holes drilled into the cap to hold the tubing, watch for the clean fluid to appear and close each bleeder when you see it come through clean. One man job.
I've never tried this approach so educate me please. Do you just crack open the bleeders, with a tube running into a container filled with fluid, and wait? Do you do one caliper at a time or all four at the same time? No pumping of the brake pedal involved? Obviously keep the master topped up so as not to run it dry. Anything else to know? Thanks.
I do one wheel at a time starting with the furthest from the master just like normal. You don't touch the pedal and no need to submerse the tubing in brake fluid, the container is just to catch the fluid so as not to make a mess. Some people may do more than 1 wheel at a time but I haven't. There are some You Tubes on it out there. I did it on my TJ when I replaced the master.
I also have an Ares power bleeder but the time to get it out and use it, then clean and put away wasn't worth it, plus I don't have the adapter to fit the Jeep master and they were on back order. It's surprising how fast the fluid makes it's way from the master to the wheels when the bleeder is open without any input from the pedal. Of course no ABS pump on mine.
Lol all these posts about "use a friend" date back to before 2020, when it was still possible to find a single human being who wasnt brainwashed with one flavor of mental health condition *or the other*
Im planning to use a suction setup to bleed mine, but Im here researching if the check-valves get in the way of air bubbles coming out cleanly?
Im replacing everything on the calipers, that Im painting, as part of an off vehicle restoration of an axle Im prepping to put in, and Im basically trying to decide if spending $20 on these instead of a few bucks each for basic ones, will *hurt* me?
As long as they dont hurt, I feel having at least a modicum of a chance to bleed my own brakes on the side of a trail at 2am drunk where a line snagged and I was carrying spares, seems logical? Right?

Yall just call AAA? or do you helivac out, leave your rubicon on the rubicon and then wait for the drunk buddies to fly back out with you by helicopter? (Im kidding I know Jeeple dont ever actually leave the pavement loool)
