Pressure loss in the brake system is getting worse :( think i need to replace the pump.
It doesn't take any longer to get up to pursue and switch off, just loses pressure quickly
 
hmmmm....

Compressor repair kit, type in amk on the Bay.;)
Like this.... It's only an experiment..

While cleaning my windscreen (so much glare this time of year) I noticed some trim on the edge of the dash has come away, might go a long way to explain a new rattle/buzzing sound. Anyone have any ideas how to refit it without removing the windscreen or pulling the dash?

I don't know about that. It will lose a bit and you'll see the fluid climb above the max but cannot recall it doing it without quite a few pushes of the pedal.
That's what I'm on about, the level in the reservoir creeps back up almost as you watch it
 
There is a valve that is known to fail. Same valve was on a Saab and some American cars. @Datatek might have the details.
The SAAB part is the pressure switch, I don't know about the valve. I did post some time ago that there might be a non return valve in the pump assembly. Mine runs the pump on start up for a few seconds but the brakes work immediately. When the accumulator was duff, the brake s were poor until the pump got the system up to pressure which took a while.
The fluid does bleed back into the reservoir which is why the level is checked with the engine running or ignition on but drops very quickly on start up.
 
Pump has started running every other push of the pedal too, uncanny. I think it's pressure loss not a dead accumulator
I’ve got similar since doing the brakes and bleeding. Starting to think something isn’t air tight, although no fluid seems to be lost. Could be I just have air trapped in there somewhere making its way around. Is in the clutch now :(
