Looking at the Willwood website at the SC1 brake calipers, thinking about using 3 (1 rear on the spool, 2 up front), but I'm having a hard time looking for a master cylinder on their website for these. Any part numbers or links to a suitable master cylinder would be great. Also, is there a biased balancer so I can set it up to be like say 60/40 or 50/50 front/rear bias? Or is it an automatic 50/50 split?
