Pressure Brake Bleeder - CTA Manufacturing 7015

I made my own with a garden sprayer some years ago, and it would lose pressure around the gauge. Then I bought a cheap one online recently which would not hold pressure right from the start. I recommend not even bothering with any of those. This CTA tool just works, no leaks, no mess, no drama, worth every cent. Having the right cap is key, in my case the CTA 7029, which has the matching Nitto connector. A+++

Extended feeder tube is incredibly convenient and you can pump from the ground. Pumping mechanism is very sturdy feeling, you will not be disappointed.

The Good: 1) The discharge hose and cap (purchased separately) are excellent quality, and the hose is long, flexible, and clear to easily view. The cap seals well and does not leak. 2) Once you work past it's shortfalls, it works well up to about 30 PSI (unfortunately, my Audi needs a little more due to running the reservoir dry prior to purchase, so this will be used for backup). 3) It has all the necessary elements to function and bottle is durable. The sub-optimal: 1) You need to take it apart and clean/reset the one way valve every day of use, and if it tips over and the rubber valve is exposed to brake fluid. - Annoying, but manageable. 2) The pressure release valve can be unscrewed and is a point of leaking until you crank it down tightly. - Annoying until you understand and fix it. Then it's largely functional. 3) To take apart (see no. 1) is not easy as the flexible gasket (presumably EPDM) sticks in the threads and interferes with unscrewing and tightening. 4) The pump gasket sometimes flips if you pump it too fast (heats up and sticks). This requires stopping mid work process, going to step 1 again, and taking it apart to fix. Likely I need to add more silicone grease to the tube to resolve this issue. I can't find it in my garage, but will as soon as I find. For now, slower, steady long pumps are the way I go. It takes a minute of pumping to get up to pressure. If not moving by 10 pumps when connected to the master cylinder, it's leaking somewhere. 5) It's a pain to clean inside the reservoir. If you are cycling fluid through the system like I was (repetitive bleeding), you'll get little debris in the bottle. While the suction tube doesn't pick them up, due to the bottle size (and my hand size), it's almost impossible to get them all out once the bottle is sticky with brake fluid. 6) When I first got it, and had all the trouble, I was ready to throw it in the woods. Due to necessity (needed to use on weekend to fix spongy brake pedal and no other options), I worked my way through the issues (engineer and son of a mechanic). Ultimately, I resolved how to make it work, partly against it's will, lol. In short, if you take your time and are reasonably willing to work within it's limitations, it seems like it will work for my lifetime.
