My 5yr old 206 has developed excessive brake pedal travel. The car still\nbrakes efficiently despite the travel which is very pronounced when the\nengine is running but the pedal has a 'conventional' feel when the engine is\nstopped. Fluid level is fine. The car is booked in for a service shortly but\nbrake wear wasn't noted last service as being likely to need shoe and pad\nreplacement this time. Is this likely to be simple brake wear, a problem\nwith the power assistance or something else?
