Review on 🔧 8milelake Pneumatic Brake Fluid Bleeder Tool with 4 Master Cylinder Adapters, 90-120 PSI - Ultimate Solution for Efficient Brake System Maintenance by Bill Roberts

This product is good for what it does. I have a small Mityvac that can do the job but it takes a lot of hand pump to flush the entire brake system. I used the product to flush/bleed all the brake calipers and lines on a 2009 Honda Accord. This device simplifies the task but still has the problem of vacuum leakage around the exhaust valve threads and fit to the exhaust valve. Exhaust valve to improve the seal, I still got a lot of air in the exhaust line to the tool. It's really not a problem for the braking system, it just makes bleeding a lot slower than it should be. I think this product will probably work just as well as any vacuum induction system. If I knew what I know now, I'd probably buy a pressure relief valve, but that has issues as well. Just a time saver compared to trying to vacuum all 4 brake lines manually.
