After lots of reading about the Motive power bleeder I finally got me one of those. BUT I'm unable to pressurize the system - leaking pressure - and it's not a faulty power bleeder (tested that one).

The cap that connects to the brake fluid reservoir is tight and I'm losing pressure somewhere within the reservoir but where? There should not be a vent or an overflow or am I wrong? Has anyone had the same issue?

TIA

Did you buy the universal adapter or German specific threaded adapter?

I have both and found that I had leaking issues with the universal. Perfect seal with the threaded one.

It would help if you put your MY in your signature.

If your car has the brake resiviour vent you need to clamp it.

Look at the forward upper side of the reservoir, some have the overflow blocked off w/ an oe plug others will have an overflow/breather hose which will need to be plugged to pressure bleed

Thanks all, found the solution. There is a vent line running from the reservoir back alongside the inner fender back towards...not sure. Putting a C-clamp on the rubber portion of the this vent line (the part is metal) allows me to build pressure. Thanks!

Spot on!

Hope it didn't **** brake fluid all over the floor.

I clamp off the hose using needle nose vice grips.

The universal adapter - good for a range of brands including Porsche. The universal is threaded as well...

I just did the update which removes the vent line, replaces the cap with a vented one, and has a plug/clamp that goes on where you removed the line.

Any special tool to install the plug/clamp?

Small screwdriver by Craftsman.

BTDT... and squirt fluid everywhere too...

these are the porsche parts, need the vented cap, and need a plug & clamp. I got the porsche one and porsche clamp, but it was way more 'expensive' than it should have been ... :-)
