I'm trying to diagnose this remotely, daughter is away with the car. She tells me that the pedal occasionally needs a lot more effort.
Fluid level is unchanged so I'm fairly sure that both circuits are leak free and probably working properly.
The car is running normally. In my mind that rules out a punctured diaphragm, and leaves me thinking that either something else has failed in the servo, or the vacuum pipe is suspect. On older cars with a laminated rubber/textile hose this would be the laminations breaking up and constricting under low pressure giving exactly these symptoms, but this is a rigid plastic pipe.
Anyone seen this - does the pipe ever suffer on Puntos?
