Five stars: Doesn't work. Please read for more information.

I'm giving 5 because the rating is going up. BUT, this thing does NOT work! I wasted an hour and a half. Half trying to get this thing to work. Air has entered my braking system. I couldn't get a steady flow of brake fluid into the hose. After much frustration, I used the tubing by inserting it into a hole I had drilled in the cap of a Gatorade bottle. I did a manual pumping by 2 people. It's a waste. The only good thing was the brake line with the black suction cup for the nipple. I would…

Pros
  • Inspires confidence

A good kit even better with a self-filling storage bottle

Works as advertised. By far the best part of this set is the filling bottle. It holds a full liter of liquid and you can clearly see the change in liquid level as it enters the tank, ensuring it stays full and therefore no air in the line. The rubber hose fits snugly over the breathers but still sucks in some air giving the impression of air in the lines. My old fluid didn't change color very much, so it was a little hard to tell if I was putting in new fluid. As other reviewers point out, this

Pros
  • Great for a small home
Cons
  • Negative impression

Makes pumping the brakes easier

Very satisfied with this product. It's always hard for me to find a buddy to help me with the bleeding. It just takes all the hassle out of it for him. Plug it straight into an air compressor, I use one of the little pancakes, and let the compressor do the hard work for you. Everything seems to be put together very well, nothing has leaked after double use on two different cars. Good quality in a good design, not much but I can ask. I can't even buy anything similar locally so I just have to…

Pros
  • Lots of positive emotions
Cons
  • Don't know

Cuts your break time in half!

If you do everything yourself like my husband, you really need this brake bleeder kit. I actually bought it as a gift for him, but it's also a gift for me. After helping him bleed a million times, this is probably my least favorite thing. Not that it's difficult, just annoying, but very necessary. With this handy tool, my husband no longer needs my help to apply and release the brakes to bleed all the air from the system. He can do everything himself and it's not difficult. This kit is designed

Pros
  • Still satisfied
Cons
  • Nothing

Couldn't get it to work as advertised.

I ordered this device to change the brake fluid myself. I received the device yesterday; Started draining the brake fluid this morning. This device worked well for getting fluid out of the tank, but when I got to my calipers it went sideways. What should have taken 10 minutes took an hour and this system blew so much air into my braking system. 1 hour later I was still trying to purge air. It was a big flop, I took the car for a test drive and it was in full swing. I had to grab a neighbor and…

Pros
  • Impressive
Cons
  • There are more interesting options.

Fast/well done.

I struggled to bleed the lines after a complete replacement of the braking system: new Power Stop rotors, carbon/ceramic calipers and pads. My wife was a champion pumper for me and seemingly blister free. I got behind the wheel and the pedal was never hard. I tried the hand pump option I bought because of vacuum issues but it just didn't work. I'll pump the vacuum up to 25-20 mmHg. and vent to 10-5 mm Hg. My hands hurt from pumping and I just didn't have enough fluid/air. The biggest advantage…

Pros
  • Free for educational purposes
Cons
  • Functionality

Large bleed valve

This is a bleed valve, NOT a hand pump. If you have an air compressor, bleeding the brakes will be done by one person instead of two. Convenience is very beneficial as it saves a lot of time and makes work easier than usual. Supplied with two lines: one to bleed the brake lines and one to drain the brake fluid reservoir. The one for the brake line has a black nipple that seals the line perfectly. The siphon line is great because it has a bent hard plastic tube at the end that is held in place…

Pros
  • Easy installation
Cons
  • Compatibility

Worked great! Tool for bleeding the brake system

The kit for bleeding the brake line includes two hoses. One of these you would use to bleed the brake fluid directly from the master cylinder. And other hoes have a connector that connects to the exhaust valve on the caliper. This is the tubing I used and here is how I used this kit. 1. Filled the reservoir with Dot 4 brake fluid my car needs. Pull out the filter at the top of the master cylinder and set it aside. Turn the refill bottle upside down and insert the end into the top of the master…
