The master clutch cylinder is bolted to the pedal box at 6 and 12 o'clock above and below the piston arm, making it difficult to access the bottom bolt. The confines of the pedal box with the pedal arm and piston effectively block direct access on that side and the cylinder itself makes it impossible from the other.

Finally got the old cylinder out. I've not had a proper look at it yet, but it looks like the spring has seized in the piston. Rather than try a repair kit, I've got hold of a full replacement.

We'd decided that the master and slave clutch cylinders could do with replacing as the seals were very likely gone on both. The slave cylinder was first to come off.

The clutch is the main problem with the car at the moment, so the first order of business was to have a look at the piston going into the master cylinder. A little bit easier than said as the pedal box cover was totally rusted up and the screw heads just failed, so we had to revert to drilling out the screws to release it.
