Car, '96 A4 Avant, 1.9tdi 110. 140k.
Only bought it just over a week ago, cheap reliable motor for the Mrs

Its started to have a couple of problems-

Brakes, no lights on, they seem to work fine for slowing down, when when slowing to a stop, in the final few feet of stopping, i can feel a bit of a jump in the pedal, and a sound that i would describe as a bit like a spring releasing.

Second problem, the clutch pedal feels okay, perhaps a bit on the high side unless thats just the norm for the car, but occasionally is a little hard to get into gear especially at standstill.

Am i right in thinking the car has a hydraulic clutch? which shares the fluid with the brakes? Possibly air in the system? Am i barking up the wrong tree here?

Thanks
