Hiya.
Weird one here...
TDi 110 (AFN) 98 model.
BRakes suddenly went rubbish this afternoon... Pedal sank to floor when approaching a roundabout, then came back after a bit of pumping.
Fluid level is dropping, but no visible leaks on calipers, master cylinder, ABS unit etc.
It's now intermittent and sometimes pedal is "ok", other times it just sinks as I press it.
Any ideas??
