    The secondary assembly will do nothing when there is complete failure - NOTE THE PROPORTIONING VALVES!  IT is a combined brake, it is not INDEPENDANT!

    "Diagonal split systems were used initially on American Motors automobiles in the 1967 production year. The right front and left rear are served by one actuating piston while the left front and the right rear are served,

    exclusively,

    by a second actuating piston (both pistons pressurize their respective coupled lines from a single foot pedal).

     

    If either circuit fails, the other, with at least one front wheel braking (the front brakes provide most of the speed reduction) remains intact to stop the mechanically damaged vehicle.

     

    By the 1970s, diagonally split systems had become common among automobiles sold in the United States. This system was developed with front-wheel-drive cars' suspension design to maintain better control and stability during a system failure.

    The diameter and length of the master cylinder has a significant effect on the performance of the brake system. A larger diameter master cylinder delivers more hydraulic fluid to the caliper pistons, yet requires more brake pedal force and less brake pedal stroke to achieve a given deceleration. A smaller diameter master cylinder has the opposite effect.

    A master cylinder may also use differing diameters between the two sections to allow for increased fluid volume to one set of caliper pistons or the other.

    A proportioning valve may be used to reduce the pressure to the rear brakes under heavy braking. This limits the rear braking to reduce the chances of locking up the rear brakes, and greatly lessens the chances of a spin."

    What rubbish, if the brake caliper drops off then it doesn't matter how much you press the brakes the fluid will just take the path of least resistance and the secondary circuit will do virtually nothing, the brakes will not be two entirely separate circuits, they will be LINKED as are most Honda setups. They are not totally independent.

    What rubbish, they are totally independent, on the pressure side. They do share a master cylinder reservoir, on the low pressure side. 

    There is enough travel designed into the pedal movement to allow failure of one side - the pedal should just drop lower, then the good circuit pressurizes.

    And I thought driving schools taught how to brake with the engine and gearbox in case normal brakes fail.  Also, normally the brake pedal affects the front brakes, and you can still use the handbrake for rear brakes.

    Major question, Raro - you should have two hydraulic brake circuits - sorry, you HAVE two hydraulic brake circuits - even failure of one circuit, one still working should provide enough braking for 90% of stops, possibly with higher pedal pressure, & also perhaps a bit of a pull to one side or the other.

     

    You need to ask Honda -

     

    P.S. Glad to hear you have started to use the brakes, at least occasionally -

     

    P.P.S. Hey, nice pink dot, Raro!

    you found what, someone that does a little bit of research? What does NASA say about it?

    Irrelevant, Danielle.

     

    The planet is infinite, or the planet is finite. Which is it?

     

    Gulf of Mexico polluted, half the Great Barrier Reef dead, you say carry on?

    It just needs someone in authority to say that sterilising these soi dogs will keep tourists safe and benefit tourism and ...Voila!....budget found and problem solved in a flash.

    Many tourists are bitten by dogs here. Seems they have a taste for 'aharn falang' ?

     

    My frontage is abt 12 m. Once or twice a year Thai kids come off their motorbikes RIGHT IN FRONT OF MY PLACE after they have been chased by dogs. Won't calculate the cost to Thailand - and the death or two, or hundreds countrywide -
