Bleeding Rear Brakes - BX

[Roscoe]

I tried that tonight after getting home and if I move the height lever to high immediately after shutting off the engine, the rear of the car will rise a bit. If I wait for 30 seconds or so after shutting off the engine before doing it, nothing happens. Same for sitting in the boot - car will sag and then raise up if I do that right after shutting off, but if I wait for 30 seconds or more, nothing happens. This is with an accumulator sphere that comes off a car that only ticks every 45 seconds or so. Strangely, the TZD pump makes the 'whoosh' noise every 3-4 seconds, but I only hear the loud accumulator 'tick' every once in a while - it's hard to time as it seems to vary. Sometimes every 4 seconds, sometimes every 20 seconds, but the 'whoosh' sound is pretty much constant at 3-4 seconds.
