Review on ABN Universal Brake Bleeder Kit with Vacuum Pump & Brake Bleeding Tester - Ideal for Automotive Service & Airtight Food Canning by Brian Warmack

Unbeatable for the price. However, you must press firmly on the rubber gasket that goes over the zirconia fitting. If you don't, it will suck air through that fitting and give you a false reading of "air in system". That aside, it's a fantastic device considering the price. I have used it to bleed the brakes on 6 cars (2 muscle cars) and have 3 other muscle cars in my personal stable and will be using this device on all of them.
