Review on Improved SEO: Motive Products 105 Brake System Power Bleeder by Jacob Seymour

The adapter in Kit 105 is smaller than that in Kit #0115. The smaller size fits older dual reservoir cast iron master cylinders. However, this is not enough for later plastic tanks. Maybe that's why some had problems with the sealing. In my attached photos, the smaller 1105 adapter is included with the 105. As you can see the adapter on the right (1115 sold separately) is much larger and should work with molded and plastic tanks. The reservoir on the smaller adapter is for my Camaro 89. It needs to be perfectly centered to ensure a tight seal. The folding system can make this difficult. Also make sure the breather is level. The fluid hose has a brake fluid inlet pipe inside. If it gets low enough it will take in air you don't need.
