I'm resurrecting this thread to warn people who may be using the Motive pressure bleeder. I used the Motive on my Subaru previously with a separate adapter for the reservoir which worked great. I put the European aluminum adapter on to bleed the brakes on the 135 this weekend. The aluminum adapter has a rubber gasket you must insert to ensure a seal when connected to the reservoir.

I should have tested the seal just using air at first, but I didn't due to the success using the Motive with the Subaru. It turned out that my gasket didn't exactly fit the aluminum adapter causing me to leak brake fluid all around the reservoir.

I ended up resolving the issue by buying a proper sized o-ring and inserting it into the adapter which worked great. In short, verify everything is sealed before pressurizing the Motive with fluid in the tank.
