I bought the Motive product one listed in the link but the flat aluminum plate (red) did not fit my Wilwood big bore master cylinder as indicated
..It was about a 1/16 off so it didnt seal very well and made a mess so i just bleed the ole fashion way...
I did use it on a standard master cylinder on a friends Hotrod and it worked fine. Poor fluid in, pump it up and bleed away...
More than welcome to try it if interested..
