Thorstone Brake Bleeder Kit with Hand Held Vacuum Pump Tester | 16pcs Brake Clutch Bleeder Tool with Adapters for Car Kitchen Uses | One-Man Brake Bleeding System Apply to Bike, Motorcycle, Car, Truck

I apparently got some fluid in the pump by my not noticing I had turned the catching cylinder and sloshed fluid into the lid and so subsequently sucking the fluid into the pump. So be careful to keep the cylinder upright and dont overfill.Disassemble pump, cleaned and dried it out, and put back together. IT's back to function. I've used for a few projects including bleeding brakes and taking oil out of a grass trimmer.Typical tiny font difficult to read instructions.

The tool meets its advertised functions... mostly. The vacuum pump is metal, the vacuum pump's fluid coupling devices and tubing are plastic or vinyl hose. The pump did provide over 25mmhg of vacuum when one's finger is used to restrain "air" from entering the vacuum pump path. My reading was a few points over 25mmhg.The use of this tool takes a bit of reasoning as to how effective it can be when drawing a vacuum from a brake hydraulic line when the ZERK fitting is loosened to pull a vacuum. A great deal of attention needs to be focused on the "loosened" ZERK fitting, because AIR is drawn into the vacuum pump through the loose ZERK fitting threads. This loose ZERK arbitrates between air in the brake fluid and the air path through the ZERK threads to the vacuum pump. When using a full covered ZERK with the vinyl tubing, then air is allowed to enter the vacuum pump through the ZERK threads; however, there's a bit of ambiguity of how much "suction" of air in the brake fluid can occur vs the ZERK threads when a pointed TIP is inserted into the ZERK fitting opening. Just wonder how much air from the ZERK threads will enter the pump vs the amount of air that can be drawn through a pointed device inserted directly, via the ZERK opening into the brake fluid, it would seem that a better brake fluid air diminishment could have occurred with the pointed vacuum adapter inserted directly into the brake fluid stream via the ZERK fitting fluid drain hole.

Does what its supposed to. Any purchaser be careful, I spent 4 hrs bleeding brakes with this to find out air was getting in through the threads on the bleeder valve on my motorcycle. I would recommend using this tool to get fluid all the way to the caliper then bleed the rest of the way by using the brake and bleeder valve.

It's a great little pump set. Worth the price you pay for it. Not the most robustly made tool but highly effective nonetheless.It bled the brake system on my 78 Camaro very easily at all 4 corners. I would recommend it to anyone. 👍👍

Using this kit was marginally helpful. I ended up bleeding my brakes in the normal messy way after trying to use this kit for a while.the pump, hoses and containment vessel work just fine. The main thing making this kit hard to use is the fact that none of the bleeder valve adapters fit snuggly on my valves. I don't know if the bleeder valves on a Chevy Colorado (2005) are just particularly small, but I figured there can't be that many sizes of valves out there.The kit comes with 3 sizes of adapter boots. The smallest one fit reasonably over the valve point but would not stay on without holding it with a finger. This was a clumsy effort trying to pull suction with one hand while the other simultaneously held the boot in place and operated the wrench to open and close the valve. If I removed my finger from the boot it would pop off and lose suction.One would think the boot would have a rib inside it similar to how the dust caps are shaped, but no the insides of these boots are completely smooth, so they won't stay in place without help.

As stated by another reviewer the o-ring for the catch bottle does not have a spare. Mine had a crimp in it but after a lot of work I managed to get it to stay in and seal.The reason for the 1 star: It took 30-40 full pumps to get the gauge to start registering. Just to be sure I connected just the short hose to the pump and plugged it up with a tapered rubber stopper. Same issue. There was some vacuum but the gauge read 20 even after all the hose was removed.It did pump I guess as set it all up like I was going to bleed brakes and placed the end in a cup of fluid. Sucked it right up after pumping 20 times. That's a lot of pumping. Gauge still reads 15 sitting in the box.I took it apart and no obvious damage to the soft parts or rings. Gauge is junk; never could get my brakes bled - had to find a helper to do the pump and bleed method.Would not recommend - or at least try it right away; not a few months later like I did. At least if you have prime you can't send the POS back.

I am using this and my muscle power to vacuum seal my glass canning jars when I store my dehydrated items in jar for food storage. It takes a little power and I know my old hands are benefiting from the exercise! This item is what creates the vacuum, but you also need the cover things for over the tops of the jars with lids on them. The cover things don't come with this item and need to be purchased separately.

What able to pull about ~21 inHg (according to the included gauge). Never exceeded that. Bought to assist in bleeding a ford explorer (1993) clutch master cylinder. This has the same goofy design that the ford ranger has in that vintage which makes it nearly impossible to bleed. It was helpful in removing air from the line (after removing the entire assembly so that I could straighten/twist it to allow air to be free to float up). I consider it a useful tool to have in the future (for only $20). It is not all that well made and the pump mechanism is a little cheap (the pin that captures the pump handle fell out). But I will keep it and find uses for it in the future. But it did not really solve the original problem of bleeding the clutch.
