    Dear all..
    I need some comment and suggestion regarding brakes system.The brakes
    spongy.I tried to bleed the system with the engine running but show no improvement.What could it be?Is it any air leak from brake servo unit?Or do I
    make wrong procedure for bleeding?Or still have 'air-trap' in the system?
    Help me...
    Thanks in advance!!

    Regards
    Hans

    How or when did the brakes become spongy?

    I thought you needed the SD2 system to properly bleed the brakes. It is all to do with the need to open the ABS valves I think.

    It suddenly happen even in idle-standstill.There's no sign of fluid leakage.More than 5 liters I use for bleeding procedure.When apply the brake,the pedal half way down,too low.I tried to pump the brake,the pedal still in same position.I'm so curious.

    If it happened all by itself something is bad in the brake system and you need to have it looked at by a mechanic that knows 360's and their systems. Air does not just get in a brake system so no amount of bleeding will fix it. Brakes are not a good place to start to learn how to work on a car, have a pro fix it.
