1. What is the minimum fluid pressure required to open ABS check valves when power bleeding M-B brake hydraulic systems equipped with ABS?


2. There are a large number of brake bleeders on the market....

Any recommended manufacturers and models?


3. For ease of use, electric powered bleeders seem to have a definite edge over those using compressed air. Anything else worthy of consideration? Anyone have the opportunity to use Power Probe's electric bleeders?
