After a day of overheating fun on the motorway today, eventually got home and parked it up. Tried to go out in it earlier and struggled...

Handbrake hasn't worked, so I've been parking in gear. Put it in neutral and spun it over, tried to put it in gear and it didn't go. It's been stiff as long as I've had it, but with some revs/rocking it/a good shove, it's always gone in.

With the engine off it went back in and parked in gear ok. Clutch pedal did feel light and not much resistance

Any ideas, short of lighting a match and throwing it inside?

check level in res first
