Another noob question - clutch issues

So I've had a weird couple of days with the truck. Out of the blue the battery stopped holding a charge - it's been fine for the year I've owned the truck, I left the lights on on Sunday morning for about 2 hours - had to use jump leads to start the truck, truck started fine the next couple of times that day, but battery was near flat Monday morning - I figure that it's just time to replace the CostCo POS with something decent, but i wanted to ask if there might be some related issue that would cause it to suddenly fail.

The other issue started maybe the middle of last week, gear shifts started to feel notchy and when the truck was first started and doing its EFi warmup thing it was very hard to shift into 1st or reverse. Yesterday evening it felt much worse and this morning I could not disengage the clutch at all - pedal pressed hard to the floor. I did some reading and figured it must be the well-documented cracked pedal bracket, but upon inspection the bracket is perfect. The previous owner told me he had recently installed a new master cylinder, and though he has been proven to be full of $hit about many things on the truck, the plunger assembly under the dash does look very new. What I did was adjust both the plunger rod and the engagement switch out a few threads. This immediately fixed the problem, in fact I had to adjust it back in a little bit as the clutch was disengaging to early in the pedal's throw. It felt perfect, shifts were super smooth and light, so my wife drove the truck to work (10 miles), she just called and said it felt super smooth at first but by the time she got to work shift into 1st felt a little stiffer - still OK, she said, but harder than when she got into the truck.

So, am I on the verge of some major failure? anything else I should be checking? There was snow on the truck this morning for the first time this year - really a bad time for a serious issue to happen, and as usual we barely have money to pay the mortgage, eat, etc.

Follow the tubing from the master cylinder all the way to the slave cylinder on the transmission. Look for oil leaks, or wet spots. Pay special attention to the clips holding the tube to the body. Even a small tiny pin hole not large enough to visualize low fluid level can cause air to get into the system. Down by the slave cylinder on the transmission is a bleeder valve you can use to get the air out. But make sure there is no leak or break in the tubing somewhere. If you do find a leak,technically you are not suppossed to use pressure fittings for this repair, but it does work on the cheap until you do the proper repair.

:iagree:
also check the slave cylinder for leaks. out of the 3 toyotas i have owned i have seen the piston seal on these go multiple times. they make rebuild kits for these for pretty cheap too.

In the mean time, until you locate your problem, try double-clutching and see if this helps your issue. It's not a fix, but rather it CAN be a good way to "nurse" it for a bit.

If you're not familiar with double-clutching:
- Depress clutch and move shifter to neutral
- Release clutch
- Depress clutch and move shifter to desired gear

You can do this rather quickly when you get used to it.

I have NO clue whether or not this would do you any good. I just thought I'd suggest giving it the old "college try"

How does that help? Honest question, I really don't understand.
