Review on 🔧 Orion Motor Tech 1L Vacuum Brake Bleeder with 8 Master Cylinder Adapters - Efficient One-Man Brake Bleeding Tool Kit by Marvin Perry

The device comes assembled in an empty carton. No direction and fitting for the 2nd air compressor. I looked it up online and it should have been pretty vague but still had instructions. And the instruction tells you to assemble the device. It appears to be a return that was resold to me. Now for the functionality. I'm a mechanic by trade and bought this for the simplicity of what an auto bleed brake does. It's very easy. Air pressure flows through the orophore and creates a suction under the orophore, that's how it works, sucking new brake fluid from the master cylinder bore through the fracture lines and filling the caliper with new fluid. Well this block is starting to work properly. But eventually it starts pumping air into the caliper. I ignored the block for about 15 seconds and as I looked at it I saw air being pushed out of the duct towards the caliper. I removed the blader and tried again. It started sucking again, then made a weird noise and started pushing air back into the caliper again. A complete waste of money and will cause more problems than anything else. Stay away. I am sending this back.
