Car problems?

Either your master or slave cylinder is out and bypassing fluid. Or just leaking it all out.

If you know where to look, you can look for leaking brake fluid at the slave cylinder or from the bellhousing. If that's not the case, then your master cylinder is probably the culprit. It could possibly be that the slave cylinder piston is mechanically broken, but that is less likely.

Either way, unless the hydraulic lines busted and leaked all the fluid out, you'll be replacing one of those two components.

Might want to ask Immortal which one is the usual suspect, since he owns a Del Sol around that year.

Edit: Arainach is wrong, the clutch assembly inside the transmission is not what is causing your problems. If you take it somewhere decent for repair, the repair bill shouldn't be more than 300, I would figure.

Jam it back in, in the dark.
