Need recommendations for a good one. Read thru some of the older threads couldn't come to a decision on one. Would like to keep it $125 or under but if ones in that price range are only OK I can go higher . Most all my work is on 73-91 GM's and older jeeps (pre '00). Thanks in advance.
 
I'm guessing the motive 0108 gm would be the one to get? ......Never had a problem before but have a '89 wrangler I swapped an explorer 8.8 with disc into can t get the rears to bleed and also a 14bff with rear disc swap I can't get the rears to bleed both also got new ss hard lines at the same time. Done both of these swaps before with no problems and only bleed those with the pedal. It was suggested to me to get a pressure bleeder.
 
My beef with the pressure bleeder is you gotta have a cap that seals to the master, and there's a lot of sizes/types of masters out there.

I did my own with a garden sprayer, spent a lot of time with brake fluid all over the motor, the truck, me, etc, and have gone to vacuum bleeding.

Far less messy, works on anything, easy peasy.

You can use a gasoline engine as a vacuum pump--all you need is a jar with a tight fitting lid ,two pieces of 3/16" brake tubing (a foot long hunk is plenty to make the two)and about 15 feet of clear vinyl hose,a pair of vise grips to use as a shut off,and you can bleed brakes and hydraulic clutches in record time,all alone,no pedal pumping either..

Sounds complicated to build,but all you do is drill two 3/16" holes in the jar lid,metal lid is best,then you can solder the tubes to it or use RTV or J-B weld putty to seal them up ,run one of the tubes down to 1/4" from the jar bottom,and the other one only needs to go past the lid an inch...
Use a jar that sturdy enough not to collapse from the vacuum..glass is best but breaks,so thick plastic is a good substitute..a mayonaise jar is good enough..

Hook a hose from the shorter tube to a manifold vacuum port on the engine,hook the other tube to the bleeder screw,and use the vise grips to pinch off the vacuum supply when no more air bubbles can be seen going into the jar..

Actually,all the jar does is prevent the fluid from being sucked into the engine--I have done it without a jar in a bind,just a hose straight to the engine,to bleed brakes...
 
IIRC, Mityvac is the good name in handheld ones.

I actually use one of the HF cheapos for <$30

I think I've had two in four or five years, but that includes a total brake rework on a crewcab (LOTS of bleeding) and many instances me forgetting to clean the thing before putting it away :doah: I really REALLY hate brake fluid.

I love the garden sprayer pressure bleeders. With one caveat- you've got to have a way to make a good seal. This can be a pain with big plastic lid masters. It works great on my screw top lids and old school cast iron masters.
 
Ive got the motive setup, and it works well.

The cap for our masters is ok, but toss the little chain things they give you to secure it. I use a maple block on top to keep it flat, and a big c clamp to apply pressure. Works great.

This ^^^^^


I can speak first hand about the same experience Dremu had. Brake fluid everywhere in the engine bay and I even had the moron moment when I busted a brand new master cylinder reservoir from trying to tightly clamp my fabricated cap in place on top of the plastic reservoir. NOT smart! :doah:

I read all the threads, and seemed to come up with the same answers from guys I highly respect, vacuum bleeding is plenty sufficient. I grabbed the big ole 2.3 gallon mityvac with pressure and vacuum, and it works awesome for all sorts of applications.

I used one before it didn't work good out of the box .

I got to looking and unbolted the top lid and it poped up 1/8" off the gasket .

the long fluid tube to the bottom was to long so I trimmed it just over 1/8" and cut 3 groves with a triangle file .

boy talk about night and day difference after words . that thing rocked .
