In Derek Seward's Race Car Design and in some of the videos on race car braking systems, such as this one, it is mentioned the use of two master cylinders, one for the front brakes and one for the back. The bias between front and back being set using different lever length between the pedal and each master cylinder.

Why is this configuration preferred over a single master cylinder of same surface area and a bias valve? Is it safety requirement to keep both front and back hydraulic systems entirely separated or is there any technical benefit?

    $\begingroup$ @RodrigodeAzevedo don't think the edit changed the meaning much - it was pretty clear before, if you are after rep then writing an answer or two is probably quicker... $\endgroup$ – Solar Mike Aug 3 at 19:19
  • $\begingroup$ @SolarMike 30 views so far. If 20% are interested in the book, that's 6 people. Does it make sense to steal a second or two from 6 people when including a link is easy? Why not include a field tag? It helps those who subscribe to tags. If the standards were a bit higher, perhaps this site would have left Beta a while ago. $\endgroup$ – Rodrigo de Azevedo Aug 3 at 19:27
  • $\begingroup$ @RodrigodeAzevedo Never even opened the link to answer the question so your assumptions about how many check the link out are most likely way off... If you write some decent answers you will help improve the standards you are flag-waving so much about... $\endgroup$ – Solar Mike Aug 3 at 19:30
  • $\begingroup$ @SolarMike It's easier to answer questions when I can actually find them. I can only answer questions in very specific fields. I am not going to stare at the front page of Engineering SE all day until something I can answer pops up. Proper tagging is required, for I subscribe to tags. $\endgroup$ – Rodrigo de Azevedo Aug 3 at 19:44

Two cylinders are often needed due to the fluid input needed by the multi-pot calipers used front and rear.

The control of balance is also handy.

  • $\begingroup$ I mean at equal surface area what would be the benefit of two vs one cylinder? (I will update my question) $\endgroup$ – ITChap Apr 11 at 19:25
