In my sixty sears of driving mostly sticks and all but one with hydraulic brakes, I have never had a catastrophic hydraulic failure; lot of leaky ones but no failures. So, it seems to me, the one reservoir / master is like having one spare for each tire - would it totally irresponsible to have only one reservoir? Makes for a much cleaner Firewall (I hate the HVAC plumbing) If one system fails it won't affect the other two even if the reservoir runs dry (not immediately) and if anything is leaking I'm parked til it gets fixed
