96 Ford Ranger clutch pedal?

From time to time when I get into truck the clutch pedal won't go down. It hasn't happened while driving. After a little time it's back to normal. The truck did sit for a year, could this have anything to do with it? I'm not sure if I should be driving the truck or not. Insight please.

Your clutch is hydraulic. Could be something as simple a a binding on the clutch actuation rod that passes through the firewall to the master cylinder so check that first. After sitting for a year with no use it wouldn't be unlikely to have clutch issues. Probably your best bet is to bleed out all the old fluid as a previous responder said but if that fails there's a couple of other possibilities. First is to change out the clutch master cylinder. They commonly develop a condition called bi-pass where the fluid leaks past the seals instead of being forced down to the slave cylinder. Another possibility is a bad slave cylinder but leave that to last because the drive line and transmission have come down to replace it.

Is this a hydraulic clutch? Sounds like the fluid needs to be flushed from sitting and collecting moisture. Just like a brake master cyl, it has a piston in a bore that could rust, get sticky. Or maybe the slave cyl is bad.

Not sure how to drain the system thou.

Use a hammer
