Works especially well when using DOT 5 fluid which likes to trap air when agitated.
I would strongly advise against using DOT5 silicone fluid in any vehicle that did not use it as a factory fill. There are compatibility issues with the rubber components, as well as issues with any moisture that gets in the system settling to the bottom of the cylinder, causing rust pitting. Had that happen to me, will never use silicone fluid again in anything other than a vehicle that sues it as OEM.
