This picture is an AFCO master cylinder designed for a remote reservoir. I don't believe this this is available any longer. there are similar but not exact available. Throughout my entire career I have had the best luck with the 74 series Tilton masters, less wheel drag and long life. The AFCO's and Wilwood were patterned after these. Typical is a 7/8" front and 1" rear bore. You can run identical bores on both front and rear but occasionally have a brake balance issue that you cannot adjust with the balance bar on the pedal.
