Clutch pedal adjustment?

My '95 Tacoma (2.7L) has issues with the clutch pedal. Clutch itself feels fine, and shifts okay, but it feels like it needs to be on the floor (or close).

Its the same for Starting. I have to push the pedal down really far.

Is there a way to adjust the clutch pedal so the clutch engages and the starter switch works with the pedal not so far down?

I searched, but the only promising threads I found were older with broken links.

Thanks

 

Yes the clutch pedal has a locking nut on the master cylinder rod, the clutch start cancel switch is also adjustable in the same manner.

Just look under the dash at the clutch pedal and you'll see what I'm talking about.

If your clutch needs that much throw and thus adjustment your clutch disk is probably getting pretty wore out. I would start budgeting for a disk pressure plate and flywheel at least, main seal pilot and throw out bearings for the whole shebang.

 

Use a turkey baster to drain the clutch master cylinder and fill with fresh
DOT 3-4 It will make a difference.
Do this a few more times as the fluid darkens. Clutch bleeding can be tricky and it's very easy to end up with air in system by trying to bleed.

 

A worn out clutch disc is indicated by engaging at top of pedal.
Having to depress the pedal fully does not indicate worn disc.
If the clutch engages while holding pedal fully depressed in gear for over a minute the hydraulics are kaput or you have a pressure leak.

 

Thanks,
I didn’t time it but I sat at a few long stoplights with the pedal engaged and in gear, and I didn’t feel anything or hear the engine speed bog down, nothing to indicate the hydraulics were leaking internally. Reservoir looks full.

I’ll try to adjust the pedal.

thanks everyone

 

What color is the fluid in reservoir?
Brake fluid is Hygroscopic
It absorbs water and turns Amber to black in color.
Fresh fluid is clear.

 

Your clutch pedal assy probably needs to be rebuilt. My 3rd Gen 4Runner had the same symptoms, esp with the pedal down start switch. (corrected with clutch pedal rebuild)
When the bushings (for the clutch pedal) are trashed, it throws off the alignment with switch, and with the "throw" of the pedal in order to disengage the clutch.
Funny there was just a related post on this...

The silver part on clutch fork has been known to fold over also

 

I looked for my turkey baster but couldn’t find it, so I’ll got my mY t vac bleeder kit to duck the fluid out...

I was looking under the dash, and saw that the pedal needs to go down pretty far to trigger the switch, so if I adjusted the pedal up, not sure if it may over-center the clutch when starting... free play ( with my hand) feels okay, maybe 3:4 to 1 inch, do near the top.


Then today I noticed something.

while sitting at a light, in neutral, I was tapping on the clutch pedal to the music and I noticed I could feel where the free play ended... but the all of a sudden I could feel as though the pedal dropped as if the line/ hose broke. I had to have the pedal near the floor as usual, But then sometimes if I pumped the pedal, then the engagement occurred with the pedal higher...

just seemed random and I was thinking “ failing master cylinder.” But it was random. Then while sitting at a stoplight, I pumped once, got the higher pedal and put it in gear and kept the clutch pedal with just enough pressure to keep it all disengaged. Truck never moved, Tom never dropped, So it’s an intermittent issue?

no loss of fluid, so I am guessing it’s something to do with the master?

intermittant swqueak under the dash with the pedal too. I’ll look at the pushrod and look into the pedal rebuild...

any other suggestions?

 

That sounds like either a failed master cylinder or air in the lines or both.

 

The silver bugger in pic is wonky
Or the bracket weld broke free from firewall. Both happen

 

Have someone keep on pressing on the clutch pedal and take a looksy at the clutch slave cylinder. Also see if the pedal itself is not broken.

 

Looked under the dash, everything looks fine. Nothing appears broken or missing.

surprised to see a linear spring for the clutch pedal return ( and no sign that it ever had the torsion spring).

pedal has a little play, about 1/8” at the foot pad (measured off the brake pedal). Looks like the main pedal shaft bushings, no other movement.

looked like maybe some side to side play where the push rod enters the rear of the master, but no signs of leakage.

in the engine compartment, everything is tight and dry, no signs of anything broken or loose or leaking. Fluid was full, a little dark so I’ll look at changing it...

 

I think I’ll replace the master, the slave and the rubber hose. I have seen brake issues with hoses collapsing internally... but still the intermittent nature with a mechanical system puzzles me a bit...

 

Interesting that your Tacoma (6 lug) has the linear spring, I'd only seen those stock on the 5 lug 2wd models.
The 6 lug 4WD Tacomas and all 3rd Gen 4Runners typically have the torsion spring. Maybe because yours is a 3RZ? (my 3RZ 4Runner has torsion spring, ???)
So that's definitely not the issue, I'd start with a complete flush/bleed, then look at replacing the master and slave cyls if the flush doesn't change it.

 

Looking through the Toyota Parts Books (on-line from various dealers), and for the 95.5 Tacoma, they only show the linear spring. There are no diagrams or part numbers for the torsion spring or the bushings for that spring.

 

I have ordered new Aisin master and slave cylinders, and a new hose. I am also thinking of ordering new hardlines (just because local Toyota dealer says they are like $11 and $8 each)... I figure that way if I can't break the old tube nuts loose... I'll also pick up the pedal bushings and a few other pieces.

Driving around yesterday and today, and I think its the master that's failing (maybe the slave?). If I pump the pedal before slipping into gear, the release is mid-height, feels right... But after a few minutes driving or idling, its back near the floor... A few times while in neutral, I swear I could feel the pedal slowly dropping with only some light pressure applied. Of course, other times I can hold the pedal down in gear, and it never releases enough to start engaging...

Its pretty consistent once I pump the pedal.

Probably be a few weeks before I can gather all the parts and get them all installed.

 

Good info! I looked it up also, under the fitment for the linear spring 1995-2004 all 2RZ (2.4) and 1995-2004 3RZ (2.7) Tacomas are listed. So on 1st Gen Tacomas only the 3.4 V6 got the torsion spring.

 

What does the "Torsion Spring" look like?
Mine looks like it is "sprung" in the middle of it.
Is this normal? Do I need a new spring?
The pedal doesn't always return to the right position. When it is working properly, all the pedal & push rod measurements seem to be correct. I know I need to change the Dot 3 fluid, once I get a turkey baster.
Just got this truck. 1999 Tacoma SR5, V6, 346k miles.
