Clutch Not Always Disengaging

I just got my first second gen last week. It is a 2005 4.0, 6 speed manual, TRD off road. From time to time the clutch doesn’t want to fully disengage. I will have the clutch pedal firmly on the floor and the truck will still want to lurch or slowly jerk forward. Obviously it is very hard to pull the trans out of gear and into neutral when this is going on. I thought it was very strange that it sometimes doesn’t have a problem and other times does. Shifting is also randomly very notchy. Before I dive into it are there any common issues that would cause this? Thanks for any answers.

 

Have you adjusted your clutch throw rod at the master cylinder?

 

I’ve heard by now it’s a good idea to replace the master

if your pressure plate is original I bet the fingers are bent too

 

Take a look down by the clutch pedal. You’ll find the master cylinder. Good chance it’ll be wet with brake fluid on it and the carpet below.

If you need to replace it due to leaking, be prepared to get frustrated. If you’re a 15 year old circus contortionist with the hands of a 7 year old girl, maybe not. It’s one of those parts that seems like Toyota started there and built the truck around it. The existing mc is probably plastic, the replacement should be metal.

If it’s dry, you could try bleeding it. I used clear tubing on the bleeder, the other end in a container of brake fluid. Pump the pedal up and down, you might see bubbles pushing out then slightly back in. You might need to use your hand on the pedal. The shared brake fluid reservoir is chambered so you shouldn’t end up with brake problems but it empty’s quickly so keep an eye on it.

Boy you ain't lying.

I've found it's easiest to pull the drivers seat so I can lay down and get on my back if need be.

Even worse on the offroads as the brake pedal has extra junk linkages on it.

Another reason I went to the steel FJ pedal and 3rd gen parts so I wouldn't have to get in there again, serious annoyance, lots of little cuts from all the stamped steel razor edges in such a tiny place then the frame is for some reason two pieces that never want to align with the pedal pivot being the primary combining point for some reason.

I'm sure some engineer is just rock hard with how clever and efficient he was with that design and I'm sure there's a thousand more techs who would love to meet the b̶a̶s̶t̶a̶r̶d̶ guy.
