vaccum leak? there is no vacuum. much more of hydraulics. check for leaks in the clutch slave and master (check this inside the car). If ok, any noise coming out of the car? noise that goes away when you step on the clutch? btw, how many miles do you have on it?

You still may have a problem with fluids, even at 46k. Defects can happen. Further more, a 20 year old car with no mileage may still have some wear.

Here's a helpful set of steps to getting your clutch to work better:

1. Change the fluid
2. Bleed the system
3. If you still have the problem, replace the master and slave clutch cyls. One of them is going bad, and when one goes the other is close, if not already gone. They're a little over a hundred dollars for the both of them and easy bolt-out, bolt-in replacement.

The reason it is soft at the beginning and harder later is because there is air *somewhere* in the system or the fluid is bad. When that's happening, you just have to pump the pedal a bit before you take off or when you're sitting at a stop light, this builds pressure.

The air could be in there from just a long period of time, or fluid could be leaking out of the master or slave cyls, causing the problem. Until the money, you should be alright just bleeding often. The system is a relatively simple one with only 4 parts. Pedal, Master Clutch Cyl, (line), slave clutch cyl.

Hope it helps
Jon

Oh, and buy a Heynes manual, it's the best 20$ you'll ever spend.

BTW victoria british has rebuild kit for the slave and master cylinders for alot less than new ones, they are easy rebuilds too.

But from the sounds of it you need to bleed it, replaceing the fluid wouldnt hurt either (had the same thing happen 2 days ago)

Rebuild for the master and slave cylinders are not too reilable, because they fail faster after the rebuild. It is usually money ahead in the long run to just replace the two cylinders, then to keep rebuilding them again and again

with the relatively low amount of miles, the pistons and cylinders shouldnt be worn much at all, it the cylinders are bad it will be from the o-ring aroud the piston dry rotting, in this case a rebuild should be good.

But you are right usually people rebuild cylinders that have much, much more miles, and then they arent so reliable
