I've had a hissing from the brakes after I release the pedal. I told hubby who could'nt hear it... so it's ok then innit? :D So now it's got worse and hisses all the time - and is languishing in a joe bloggs garage. "Joe" says it's the servo seal which cannot be replaced separatly, and that a vacuum pump has also gone wong because of the servo's failure which overworked it. Does this sound about right please? EDIT: The engine power has also drastically dropped
