RE: Accumulator bomb?

["Reid, Les C." <Les.Reid@centrilift.com>]

Thanks for the input Aleksander,
That's correct, the h-oil level rises in the reservoir after a while when
off.
Does this mean a new master cylinder?
Any suggestions how to trouble shoot the problem?
What am I giving up, safety wise, if I don't fix the problem?
My understanding is the bomb provides some power to the brakes/steering if
the engine dies when driving. Does it do any thing else? 
Les

The bomb should hold pressure after the engine is shut off, if it doesn't
(the fluid level slowly rises after shutdown and then starts to drop after
starting the engine) then you've got a leak somewhere. The leak might be
internal, the most common cause is the brake servo not holding pressure and
leaking fluid back into the reservoir.
