Photoweborama So many options, and even the expensive ones aren’t that expensive...

Sc_trini I did all 4 corners using a Pneumatic Bleeder from Harbor Freight. It costs about $40 at most and I was able to do the job myself in an afternoon.

Can also make a one-man bleeder for manual bleeding out of an old (clean) gatorade bottle, and some aquarium tubing if your helper happens to be busy. drill a hole in the cap of the bottle, shove the tubing through the hole all the way to the bottom of the bottle, drill a tiny air relief hole in the cap. fill bottle about 1/4 to 1/3 of the way with clean fluid.

Never had any issues with manual or one man bleed, can be done pretty easily without even raising it. Just as easy to flush, I did it this way last brake job, may just flush every brake change since it doesn't get driven that much anymore and it's so easy.

If you're replacing calipers, you might as well replace brake hoses if they're original. Front hoses are easy (though mildly tedious), haven't done rears yet.

I have one and it works great, when it seals. The vacuum cup doesn't want to seal all that well. Fittings/tubing could be better as well but it still works.

I found one from the '90s I had left in my parents' garage. It still worked fine after putting a bit of oil in it to lube the seals. It wouldn't move otherwise.

Wabatuckian Gravity bleeding = slow, least work, requires one person
Manual bleeding = faster, most work, requires two people
Suction bleeding = fastest, medium work, requires one person with equipment; most expensive

Wabatuckian I've done both power bleeding (with a hand pump) and manual bleeding on my WJ. No problems with either method.

BrokeJeepJoe I replaced the front to rear line recently. Gravity bled the rears and then the fronts. I bleed brakes a little different than most. I don't pump the pedal and hold, I open the bleeder and push the pedal down and hold then close the bleeder. This is all after gravity bleeding. Learned that method from an old timer when I was in my teens which was many many decades ago and it hasn't failed me yet on any vehicle I've worked on ABS or not. I also replaced every line on my YJ and TJ and used this method without fail. Just make sure you have good flow when gravity bleeding. Patience is the key!

That’s how I used to do it years ago, except I’ll be replacing the cement block with my son..

I have to replace calipers on my WJ this time and I wasn’t sure if this method was still possible on these “new fangled” cars...

DJCantonGA I'm planning on doing my front brakes tomorrow, and I'll bleed all 4 when I'm done. The fluid needs replacing. I'm using a vacuum pump I picked up at HF. There are several good YT videos, it's not a bad job at all.

By manually, are you referring to gravity bleeding? If so, you can, and there are good videos on that method as well.

WJ’s and manual brake bleeding

Can you manually bleed the brakes on a WJ, or is there something that makes you use a pressure bleeder?
