W87030 Hand Vacuum Pump Brake Bleeder Kit | One man automotive fluid bleeding and vacuum testing. Diagnoses systems and bleeds brakes. Complete kit with gauge

Did what I needed it to do. I used this for a vacuum filter flask, it’s a bit weak but if you’re using it for its intended purpose then that won’t be a problem for you. I appreciated the multiple adapters that were included!

I got this to replace a 40 year-old Mity Vac that couldn't be taken apart and serviced. This one works great, pulls a good vacuum and holds it. It's even easy to take apart and clean, which I had to do because I accidentally connected it to the wrong fitting and sucked a bunch of brake fluid into it. Doh! But no worries. A few screws and it was apart, all cleaned up, relubed with silicone and is ready to go again.

Comes with some hose and several adapters to fit most hoses in your application. I was most interested in vacuum testing and hand pump. The adapters are made of some "soft" black material. May want to get better adapters if you use it a lot.

This pump is awesome works very well, i purchased this one to replace other branded one that keept leaking cant have that when testing parts for leaks. Look high quality great value.

I needed to check the distributor vacuum advance for my 1959 Nash before I assembled and re-installed the distributor. I have several old spare parts and wanted to try to find one that would work. All 4 pulled in with vacuum but also leaked out in a few seconds. It didn't make sense that they were all failing at exactly the same rate so I checked the vacuum pump without a hose or connector. It showed the same leak down rate. It turns out that there are two O rings on the stem of the vacuum gauge but there are too small a cross section diameter to seal up reliably. I put in a couple .010" cross section diameter O rings with a little silicone grease to seat them. The pump is working fine for now and does not leak down. This probably would not matter if you just need to bleed brakes. If you use it to test vacuum as the description says you can, that slight leak makes diagnostics impossible. After fixing the pump I found 2 of the 4 vacuum advances are working fine. One is scrap and one has a very slight leak. In general I do not like to repair or re-engineer things I buy new but this was a quick and easy fix that enabled me to get my car back together this weekend.

The pin holding the trigger mechanism to the piston that operate the pump is garbage. It broke the first time I used it -- pin slid out of the groove that held it in place, and was impossible to reset with any reasonable amount of effort. On inspection it's obvious this is a badly designed unit with an obvious weak spot at a crucial location. I would have returned it, but the return window was closed by the time I got around to doing the job I'd bought it for. I eventually managed to use a vice grip to lock onto the piston and manually push and pull to pull the relatively small vacuum pressure needed for the job....oakie powers in effect...but this unit is garbage.

Worked as it should Fast shipping Good price

Hope it lasts - had a Different manufacturer which lasted since. 1986 - lost a pin on the vacuum - will let you know how it does

Very well designed. Simple to use. Very effective kit in maintaining those sharp breaks on your vehicle.

Bought under good condition. Working well only when their is zero air intake in the system. So make sure of tight fittings and connection. I used this product to bleed back how loader master cylinder. I first bleeded the cylinder unit first. While doing so, slightly pedal for 20 to 30mm, it will bleed effectively ( flusing + sucking ). Given 4 star only for product packing. Would they given with container box for storing.

Works as intended
