Reviving this thread after it just happened to me.
Basically every reported noise, in tandem, happened to me.
Noise when fully depressing the clutch, if I could describe it, it sounded like hydraulics actuating in high pressure mixed with grinding noise and goose honk. This are the steps that I took to pinpoint source of squeak.
1. Replace Clutch Fluid
2. Grease the Slave Cylinder pivot point.
3. Grease the Clutch fork (Remove slave cylinder without touching hydraulic lines, remove boot, feel for the pivot point and grease).
After the noise was somewhat reduced, one stayed, sounded like a bad door hinge or dry rubber being dragged across steel.
Here is the culprit
What you see above is the Master Cylinder Assembly which sits above the Gas Pedal. That rod contains a rubber seal I believe that can get dry, along with the rod, rub those together, and bam, goose honk noise. Either use a spray type of lubricant, or really get in there with Toyota recommended (
NICHIMOLY N-13).I went with Mobil-1 red grease.
