Pneumatic brake piston wind back tool?

[signcrafter]

I have a brake job coming up that has the wind back pistons. I have the astro set and also have an older lisle set, but don't have them with me. I can just order another kit, they aren't that expensive. But then would have multiple kits of the same thing. Yes I could rent a set from autozone or oreillys but I hate dealing with that and would rather just order something off amazon and be done with it. The sets I have always have worked for me but I see a pneumatic version. Figure if I'm going to be spending money on a new tool I would rather get something different to add to the collection then multiples of the same tool. Anyone have one of these sets and does it work good?

Watched a few videos on it this morning and there was a bunch of good reviews for them so I think I'm going to order one today. Deciding weather to go with the cheaper amazon knock offs for 55 bucks or get one of the brand names for over double.

They all seem to work about the same, I'd not spend a lot more on one vs the other. What I've found about them is the air pressure to force is basically locked, 90psi, there's about a square inch of piston area, it's 90lbs of push. 100psi is about 100 pounds of push, you can stop them with your hand if you curl your palm over it. It's not a ton of push back force if that was ever the aim, but if just like keeping in place and rotating then that's all ya need.

Thanks for the info. From what I see the air isn't neccesarily to push the piston back but more to keep pressure on it while you rotate. My astro set has worked good for me and thought about just picking up another set but don't need 2 of the same set so was just thinking to get something different to do the same job and then have more options in the toolbox. Does astro make a pneumatic kit? I didn't see one but would rather have an astro then a no name.

We didn't put out one because in use I didn't see the upside vs the cost and added size + having a tether - but that doesn't mean it has no use
