Motion Pro Brake Bleeder

Anyone use the Motion Pro brake bleeder tool that is a combination of the wrench and check valve? I tried it this weekend and had the tool as far onto the nipple as it could go with the socket fully over the nipple nut, but once once I cracked the valve open and started squeezing, brake fluid was squirting out from the socket in addition to some going into the tube. Air made its way into the system and ended up calling my wife into the garage to handle the lever and watch the fluid while I used the wrench. Anyone else use this tool with luck? I'll try to return it tomorrow.

You want this one...

Using the above tool I had my brake fluid completely changed in about 10 minutes, no air got in the system and only a minor weep came from the bleeder nipple.

I went back and forth between the two. I'll try that one next. Thanks.

A box-end wrench and the correct size of vinyl tubing works perfectly, costs less, and is rarely defective.

Another option...

A MityVac LINK

It has worked well for me.

this come with argon tubing or whatever that is not affected by brake fluid?

'standard' tubing tends to get hard after a few months

I was trying to go a simpler than that setup, but lots of people seem to have good luck with it. Maybe the next time I'm bleeding brakes I'll look into it again.

I haven't tried the Motion Pro bleed with check valve. But, I've tried a couple of similar types. They work OK. The mity-vac works OK also. At one time or another I think I've tried about all the gadgets available.

What I found worked the best - aside from pressurizing the master cylinder with compressed air - was attaching a clear PVC tube to the bleed nipple, route the tube to a can or jar, then open the bleed nipple and let gravity do the work. After fighting a mity-vac (which will work), watching the check valves separate from the tubing, and generally observe how anything which can go wrong will, I just use gravity draining. It works with the most complex brake systems along with the simplest. If I could, I would put a piece of vinyl hose in a box with a DVD and patent the technique. Of course, then the real work would be in marketing and convincing people to use such a simple approach.

I will admit that after installing new lines, brake cylinders, calipers, and master cylinder on an anti-lock brake system that pressurizing the master cylinder is about the only way. But, if it's just a matter of changing the fluid then opening a bleed nipple and routing the fluid to a container is my first choice. However, if someone has no attention span then I recommend they train their significant other to pump and hold the brake lever or pedal while they open and close the bleed nipple.

The gravity bleed technique is not super fast. It takes ~ 20 minutes and the master cylinder fluid level needs to be checked fairly often. If fast-fast-fast is the goal, I recommend getting some speed bleeder brake nipples which have a check valve built-in. They may need a wrap of teflon tape after being used some, but they are fast-fast-fast.
