Need some advice please. My son called today and said his clutch pedal was staying on the floor when he released it. This started just a couple of times on the way to work this am, and got worse on the way home.

I don't have a manual on the car, but IIRC this is a hydraulic clutch system. If this is the case, I'm wondering if the master cylinder (?) may have gone out. If so, what is the process for replacing it? I'm fairly capable on repairs, but I've never worked on one of these before so any information/advice is greatly appreciated.

Thanks,
Steve
