Worked well for vacuum bleeding power steering
I bought this kit hoping one of the two adapters would fit on my power steering reservoir and one did. I recently replaced the power steering pump, high pressure hose and the steering rack on my 2016 GMC Acadia and the new pump was noisy after multiple attempts to bleed the system by turning the wheel from lock to lock. I bought this kit since I already had a hand vacuum pump (pump is NOT included with this kit) and figured I would try it. It definitely helped as the pump is quieter but not dead silent like it should be. There is a good chance the pump I got is defective and should probably be warrantied out. If that is the case this kit will be needed again. As far as using it to bleed and/or flush the brake fluid, you get three different attachments with the kit so it should cover most bleeder screws on calipers. I could see this working well to remove a stubborn air bubble trapped in a caliper but for a full on flush and bleed, the two person method or pressure bleeding from the master cylinder will work better. Gravity bleeding is also an option if you aren’t in a hurry. Nice little container, plenty of clear hose and an extra o-ring seal is included for the cap on the container. The power steering reservoir adapters are worth the $20 for this kit alone.

READ THIS BEFORE YOU BUY........
I have a 2001 Ford Taurus and used this kit to get the bubbles out of the power steering system. The large rubber adapter is too small to fit the reservoir so I used the bubble pack envelope as a gasket to get suction. You’ll see what I mean in the video that I made to “mansplain” to my wife what I was doing 🤪 Overall I am happy & really like this product so I will keep it for other repairs. If you have the same Ford pump with the larger opening reservoir, you’ll need a gasket or use the padded envelope like I did.

Decent tool, could be better
As a professional mechanic I needed a way to better bleed the air from a power steering system on a Chevrolet Traverse. I saw this and for the price I thought I would give it a try. The tool function like it was supposed to and I did get a large majority of the air from the power steering system. My only complaint is with the adapters. I feel rubber of the adapters should be a little softer which would give a more air tight and secure seal. Better yet if the adapters were like the design of some coolant bleeders with an expandable adapter that once tightened would be secure and free from leaks. Again the tool is decent and I will use it again since I own it.

Sizes of stoppers in 27311 power steering adapter kit
The larger stopper is about [1 and 5/8ths] on the small side and [1 and 31/32ths] on the larger side; just under 2 inches. This makes it not work on the 2" ford power steering pumps. The smaller stopper is about [13/16ths] on the small side and [1 and 5/8ths] on the large side. To be more precise the measurements I took with a caliper read (in order previously listed) 1.946, 1.600, 0.835 and 1.625. Fractional values were first for quick reference. Measuring a rubber cone with a caliper is not ideal so measurements will be slightly off. I held the larger stopper up to my power steering pump and it was too small. I did not test any of the pieces of the kit so no input on quality other than the plastic case was very cheap feeling and the air/liquid separator looked like every other vacuum bleeding kit's you can buy for under $100. Ended up ordering the Lisle 72070 which I found measurements for showing the larger stopper being over 2 inches in diameter.

Rubber stoppers not sealing
The plugs leak air through the center even when pressed into the cap tightly. Junk. I would have returned but I modified it so it would not leak. My guess is the rubber is too stiff in the cold to seal properly.

Great kit and worth it when on sale.
No complaints from me. I specifically bought this kit to bleed the power steering system on my 4th Gen RAM 3500 after repairs. It's difficult to get the air out any other way with the hydrobooster, and the single Mopar bleeding adapter is more than double the cost of this set. The narrow cone fit the reservoir perfectly and I was able to easy maintain a vacuum to specification. Totally worth it to me. As for the complaint about the blow-molded case not holding the ported lid for the cup, that's true but is fixed simply by taking a flat file to the end of the ports. One stroke of the file to each port to remove a little material was all it took to snap into the case. Where this kit really shined is when I used it to bleed the hydrogears on my zero-turn mower after changing the filters and fluid!

Great tool.
My steering was noisy when turning due to an air lock in the system. With this tool, I was able to rectify the issue and I am now a happy driver. Great tool and very easy to use. Wish it could come bundled with a handheld vacuum pump. I had to buy that separately. However, I like the quality of this product and seller was also quick to ship. Whole transaction was smooth. I would recommend buying from this seller.

Excellent product
This product works perfectly for what I was using it for. I needed to bleed my power steering pump of air. The rubber fitting supply worked as indicated. There are two rubber seals supplied which will cover most reservoir opening sizes

Loose connection so no suction
Really disapointed, didnt fit my ford ranger power steering but that in it itself isnt the worst. Even if it would have fited, the connector are loose inside the rubber fitting... so no suction possible... I feel bad saying this but its garbage, I felt robbed.
