Master cylinder question
I know it must be simple but:-
A twin circuit master cylinder will maintain pressure to either circuit if the other one fails (leaks). So when you bleed the brakes (equivalent to a
hose break etc)why does the pedal go to the floor. Surely the pressure would be maintained to the other circuit? Not sure if I've explained that
OK

the pedal will go to the floor due to the pressure in the system being lost however there will still be pressure applied to the circuit without the
fluid loss allowing one front and opposite rear to brake for you. prior to this type of set up you would have instant failure as all wheels relies
upon the same circuirt, the new system incorporates 2 circuits as a fail safe, if it does ever go and you stop the motor dont think about carrying on
driving as the toltal fluid will be depleted at somne stage Hope this makes sense.

Pedal shouldn't go to the floor if on circuit fails --- you just get a very big increase in pedal travel.
