93 PU Empty clutch master cylinder.
So I first noticed my clutch pedal becoming very easy to press with no resistance.
I left it for a few days thinking I was being paranoid.
Decided to check the clutch master cylinder and found this...
Since there is a bunch of sludge and possible air in the master cylinder, is it possible to leave everything attached to the truck and just flush it out with fresh fluid?

Yes could be.
I don't think that this has been looked at in years so i'm going to take the cheap route and try flushing it as i'm a student on a budget.
I'll be keeping an eye on it in the future.
Thanks for the help.

I did a master/slave cyl swap on my 4Runner, its a PITA but the clutch is solid. They were very cheap from AutoZone, but the first one we got was defective. Definitely flush as well, don't want it getting into your new system

Do yourself a favor and purchase an Aisin master & slave cylinder online before you have a complete failure. Get a clutch hose too, they can cause trouble in a hydraulic system and have definitely given a few on this site trouble. When the hose gets old it'll expand a little when you step on the pedal. That slight ballooning action decreases hydraulic pressure and it won't allow full clutch movement. You can find what you need at http://www.aisinaftermarket.com/English/Catalog.php then do some price comparisons.
Here's why you should purchase the parts before you have a complete failure:
Toyota installed an Aisin brake master cylinder, clutch master cylinder, cluch slave cylinder, brake wheel cylinders, as well as many other Aisin parts while your vehicle was being built. Think of how long they have lasted and the miles on them. In some cases the online price is comparable to what the local parts stores want for normally generic parts.
If your clutch master or slave fails and it's your only vehicle you'll likely need to get it replaced FAST. That usually means generic China parts from a local parts store. Don't be fooled by the "Lifetime Warranty". If you do some research on this site you'll see a TON of out of the box failures and failures soon after that with those parts.
Another thing to think about is that if you can't shift it and you don't have towing on your insurance or there's nobody close by that can tow you,
it will likely cost you at least the price of the parts to have it towed back.
Then you still have to purchase parts to fix it

Check your floor board behind the clutch pedal. When the Master Cylinder leaks, it leaks to the inside of the cab. I would have my Master and Slave Cylinders with me before starting the job. Once you start messing with them, as old as they are and as corrisive as brake fluid is, they will start leaking.

Listen to the good advice being given here and replace both the M/C ad slave cylinder with Aisin parts now to avoid any trouble down the road. The brake fluid didn't just evaporate, something is leaking. It is just good common sense to replace them both at the same time. It's not that hard to replace them.
