I read a bunch of threads on this gizmo and it sounds like everyone has had good results -including non rx7 folk. Has anyone had a problem? All 3 of my cars have brake issues so for <$70 this thing sounds like it will save a ton of time.

Plus it basically tests for leaks in the system as well right? If you pressurize the system and it can't hold the pressure... How hard is it to get it sealed to the resevoir? It would suck to think you had a leak when it was the tool all along. Is the 10-15psi enough to reveal a leak?

I ordered the 'import' version that is supposed to fit the RX7 plus any car with a round resevoir under 3in diameter. Anyway TIA for sharing any experience/tips.

edit-oh, if you could mention where you ordered from and if they were any good that might help some people. i ordered from cdoc.com which called to say it was out of stock, i haven't called them back to see whats up.

pushing the brake pedal is the best leak tester there is... nice way to flush/bleed the system by yourself though

I love the Power Bleeder. It is my favorite way to bleed brakes.

I didn't test the seal with the master cylinder the first time I used it and ended up leaking brake fluid all over the place. That's the only problem I've had.

It does not test for leaks in the brake system. 10 psi is WAY less pressure than you get from stepping on the pedal. If you want to check for leaks, step on the pedal.

You do need to check for leaks in your PowerBleeder / master cylinder connection BEFORE you add fluid to the PowerBleeder (see second paragraph of this post). Basically, just hook it up with no fluid in the PowerBleeder and pump up the system. If you hear a hiss or it won't hold pressure, you need to make some adjustments. Do that before you add fluid or you will get fluid all over the place. It isn't that hard to get it to seal, but it can take a little fiddling sometimes. You only need to pump it up to the pressure you will be using to bleed (perhaps with a few extra psi as a safety margin).

The import version is the one I got, too, and it has worked on my FD and my '90 Integra. I ordered it from http://motiveproducts. com/ with a bunch of ATE brake fluid.

Bummer on the leak testing but it wasn't a big worry. Only problem with stepping on the break to test for leaks is you're back to having a helper. Course you could just look where the paint isn't doing so good

Thats wild max, my other ride is also a 90 integra - a gs. Just replaced the master cylinder on that (saw a thread about that you contributed on) and had to bleed it a ton! We used like 4 big bottles of fluid. Even with good bench bleeding it still needs bleeding. Great to hear it worked for you.

Question: the instructions that came with the master cylinder I bought said to install it with the brake lines loose and push the pedal to the floor. While holding the pedal (it really said to the floor) then connect the lines. We had much better results doing that but I thought putting the pedal to the floor could damage the seals in the cylinder? Neither my haynes manual or my buddies prelude shop manual mentioned that step.

edit- I didn't order direct from the motive site (which is nice) because they only take mastercard and visa. discover is my dedicated internet use card.
