Copap Hand Held Vacuum Pump Test Brake Bleeder Kit Set with Adapters Brake Bleeder Pump for Car and Motorcycles 16PCS Set

I wasn't about to drop $70 on a specialized pump when they already price gouge for decent cylinders bc they're "specialized" so that comes at a premium.It's hard enough finding stuff we can use for just about everything and I hate spending more for things than most folks have to bc of "novelty". Most cheaper options are flimsy or inefficiency, and they don't have a gauge, which is way more important than you would think!Even on the cheaper side, I was still seeing $40 for vacuum pumps marketed for use with cylinders, so I just started searching for generic vacuum pumps.I was really iffy about picking this up since it's obviously more for industrial use, but I figured $20 was an alright amount to spend to at least check out the pressure gauge and see if it was similar to the $70 ones—and it was!I tested it out on other things first to make I wasn't gonna mess something up beyond repair and honestly I felt a lot safer using something like this than cupping pumps, or god forbid, those twisty things. And having a gauge REALLY makes a difference.(Please read up on the appropriate PSI to set it at. I think it's something like 5-10 PSI, but don't quote me on that. That may sound low, but you don't want to end up in a hospital bc you broke something.)Obviously I didn't really have a use for most of the stuff it came with, and I will say that the tubing is not the greatest, and I don't think it came with a compatible coupler to connect to most higher end cylinders. For that I already had a decent silicone hose.Btw if you're still looking for a decent hose, if you just search on Amazon for a "silicone hose with male fitting" you should be able to find something compatible.You want at least 24" or it'll be a pain to use. I've found that the kind that have the little rubber O-ring on the fitting are the best (and maybe necessary for a good seal) and you can find replacement rings fairly easily if it ever breaks. At the very least you're going to need that type of fitting if you're fine with the hose it came with or want to use a different material.I will say that if you get silicone and attach it directly by to the pump, plan on leaving it on bc I've found that the nozzle on the pump really tears up that soft of a material if you keep detaching it. You might be smarter than me though and have a better solution that doesn't destroy your hose or even find a use for the other parts. I'll be the first one to say that I know absolutely nothing about break bleeding so I've got no clue what most of the things that came with it are used for.To any other guys out there, really look into MacGuyvering things for your own use instead of wasting money on the junk that gets marketed, probably by CIS (if you weren't sure about what I was referring to earlier). I'm also disabled so I'm used to having to find ways to make things work because they aren't designed for people like me in mind. There's almost always a cheaper solution with a little creativity.I could have easily dropped $100 for subpar tubing and essentially the same pump but in the end I paid less than $40 for both!

I have used one before and this one but the instruction manual that came with it is pretty straightforward and easily understandable. The product itself seems a little bit lacking. I had to make some modifications to the boots that go over the bleeder nuts and fit in to the end of the hose supplied with the product. The very first one seem to fit nice and tight but after that it was very loose and did not want to stay on at all. After I finally figured out a way to get the boot to stay on the bleeder nut it was OK, but up to that point it was a real headache trying to hold the boot onto the bleeder nut with one hand and pump the bleeder with the other hand all while trying to loosen the bleeder nut to do the actual bleeding. All in all I think it’s worth what I paid for it but it could use some upgrading to the boots or maybe a few extra boots to go along with it to fit over the bleeder nuts.

Couldn't get a great seal with it so it was difficult to see when I bled the brakes enough. I pumped the heck out of the lines until it was only micro bubbles from the seal leak, then kept going for a while after that just to be sure. So far, my brakes have been working perfectly all year, so it must have worked.

I guess it was okay? I wish I would have just purchased a motive brake bleeder like I have in the past. It did the job fine but I wasn’t thrilled at all while using it. Replaced brake lines with stainless and used this to bleed it out. I think I did get all the air out in the end but blech I won’t be using this again.-Rubber fittings for the bleeder screw did not fit my Nissan Frontier. I had to chop one in half and use it as an adapter sleeve thing instead of as intended. Even tried tie wraps to seal it. Helped but bad seal in the end, the adapter sleeve solution worked to hold a vacuum.-Vacuum is so minimal, you have to keep pumping just to retain any sort of vacuum. The reservoir is so small it’s just annoying.-This one may be my least favorite part about it. Some brake fluid managed it’s way into the vacuum pump itself. This started to aerosol the brake fluid and I breathed a little of it and got some in my face. It was not fun. A one off situation? Possibly but it could happen to anyone.It was also hard to tell when the air was out of the system. Since you have to continually pump it you just can’t tell. The motive created a nice output of fluid from the screw.Overall it got the job done but I’m sticking with spending a little more for a motive bleeder!

Cheaply made in china

Works as expected

I put off buying one of these for years and kept bleeding brakes the old school way. Holy crap this makes it easier! I bled a clutch line in under five minutes that would have taken me an hour, and buddy or wife points to bleed the old way. Buy yourself a vacuum pump!That said, the quality of this kit is good with the exception of the finishing of the bottle used to collect fluid if your using it for bleeding. The top of the bottle had just enough plastic flash on it that it would not seal and create a vacuum. I was able to carefully remove the offending plastic with a sharp blade but had this not occured to me I would have just sent it back. It wasn't even enough plastic to be noticeable, just enough to not let it seal.So, good product for the money but be prepared to have to fool with it for a bit.

It worked at the moment but it is really cheaply made. Not sure if this will hold up for constant professional use. More of a use a couple of times before it breaks kinda deal.
