Motion Pro08-0143 Hydraulic Brake Bleeder

Great product. Makes bleeding the brakes real easy.A+++ on shipping

Now I will say that I was very skeptical about purchasing this item in the first place because there are many check valve based brake bleeding products on the market right now. Many of them do not work very well; check valves will pop off from the pressure on some and others just don't seem to be able to do what they are designed to do, which is to allow flow in one direction and not the other as a check valve should. However, this was not the case with the Motion Pro brake bleeding tool.This product worked perfectly fine and finally made brake flushing/bleeding a one-man job for me. Now mind you that this is an extremely big deal as many of you know that brake flushing/bleeding is a tedious (yet enjoyable) job and can be frustrating for the slave, I mean partner, that you are getting the brake pedal assistance from. The check valve properly allowed fluid and air to flow in one direction but not back in to the caliper.However, I will say that the plastic tubings that are supplied with the check valve are a bit short. In fact I had to use my own extended tubing to be able to do the job. Therefore, be warned that you should probably get some aquatic tubing or something similar at your local hardware store (fuel tubing for lawn mowers will also work). Still make sure to use the plastic tubing the is supplied for the initial end of the check valve as it is a perfect fitting for the nipple and the check valve; only use your own longer tubing on the ejecting end of the check valve.Another thing that I will warn ahead of time is that when you release the bleeder nipple (1/4 - 1/2 turn; I personally do no more than 1/4) once you have attached the tubing, you'll notice that brake fluid seeps out from the threading. For the most part, this is normal; all you have to do is use some paper towel and shove it around the nipple before starting to bleed the caliper. Some of you may worry that air may be able to seep into the caliper through the threading since it won't be going through the check valve, but I assure you it probably will not, especially at 1/4 turn like I did. Nevertheless, nothing is perfect and it is possible that your bleeder nipple may be warn out and therefore give you a different experience than it did for me and leak air through the threading. To ensure that this is not the case, when you are done pumping the brake pedal to bleed/flush the capliper, close the bleeder nipple, use something to hold down the brake pedal (like a crow bar between the clutch and gas pedal), and open the nipple to see if air bubbles shoot out of the bleeder nipple (jury rigged one-man bleeding). Do this a few times at the end for each caliper. This will let you verify that the job was done properly.

If you were paying attention in school and learned how to read then you will be happy with this neat, keep it simple, little one man bleeder. Read and keep the instructions that come with the unit or if you can't read then find someone who can read the instructions to you. (Those of you who can read please don't laugh. You would be surprised how many people can't read Engwish ;-) Bleeding brakes is not rocket science. If you can type on a computer but don't have a clue about bleeding brakes then go to Youtube and watch some videos on brake bleeding whatever type of vehicle you're working on. Works great on motorcycle brake systems. This unit is made for brake systems that already have fluid in them. Air in the brake system is what keeps it from working correctly. This unit will bleed the air out if used correctly. You must prime the unit before it will work hence the reason for having the ability to read the instructions. The bleeder has an arrow on it to tell you which direction the fluid must flow. Use a water bottle or something similar to catch the fluid as it pumps out. Do not just pump it on the ground. Do your part to help protect our planet. Any auto parts store will take the fluid you bleed out of the system free of charge. Do not flush it down the toilet. I own bleeders that cost a lot more than this one with too many parts required that don't work as well. Another fine Motion Pro product.

works great

This little thing works perfectly! I use to use a pressure bleeder, but was concerned about what some people say, that pressure bleeders push more air into the brake fluid, which causes both more air and moisture to absorb into the fluid. Best way is to press the brake pedal, or put a vacuum on the bleeder screws. A vacuum would be nice, but also a lot more work to setup initially.Instructions say this check valve does not work on air, only brake fluid, but on empty systems you can still pump the pedal until fluid comes out, and run your drain side pipe into a container that has brake fluid at the bottom. That way you only suck back up fluid, not air. Once you have fluid in the lines, this is completely unnecessary. Did all 8 bleed screws on a Brembo-equipped car, was effortless. I completely trust this little check valve, hope it lasts. Rinsed it out with simple green and then a little PB Blaster to keep it from corroding or whatever.Remember to buy a couple more yards of cheap 3/16" clear hose from the hardware store, so you'll never run out, and can throw away what you've used after each brake job.The included hose clamp is worthless, but you don't need it anyways.Another great trick to compress pistons is to crack open the bleeder screw first, then push in each brake piston. Fluid will go out through this check valve, instead of fighting every other brake piston. Makes life a LOT easier, and does not push old fluid back up the brake lines or risk overflowing your reservoir.
