Hydraulic clutch question

I just fot an 86 T/A w/ 5 speed. It had been setting for a year or so, and the owner's brother had it before, so they don't know anything about it. The problem is, when you let the clutch out, it doesn't engage till almost all the way out. They said it slips when driving, but I didn't drive enough to tell. The pedal is tight. Is there any adjustment, or could it possibly have the wrong throwout bearing, or is the clutch just worn out?

If its at the top, must be a good clutch. One thing I don't like about the hydraulic system is it engages so darn high. When the pedal gets low, that is usually the sign of a clutch wearing down.

There's no adjustment. The hydraulic system is inherently slf-adjusting.

If the clutch doesn't engage until the top, it's worn out. Basically your car just needs a clutch. No big deal.

That's pretty much what I thought. Also, the car has a disc brake posi rear, but the RPO codes say it is drum. Can you identify the gear ratio by the posi tag?

The tag could be just as wrong as the RPO codes. 50% chance; either it's right, or it's wrong. Tags are alot easier to swap than rear ends, or even carriers.

Take off the cover and look. It's the only 100% sure way to know.

Same for the posi. Look, otherwise you can't be sure.

Thats strange though, on my t-5, when I put in a new clutch, the engagement was alwasy very high, right about a 1/2" from the top. Even on my T-56 with brand new hydraulics and a brand new Spec Stage III it grabs really high.

"put in a new clutch and have high engagement" is a totally different situation from "I just got a car and the clutch slips and the engagement is real high".

He never stated it slippeed, but was told it did. They say they know nothing about the car, may be like my cousin when the moron said thier was something wrong with my clutch because it was so high.

Nope.

When a disk becomes thinner, the pressure plate fingers become higher, which puts the pedal higher.

So, more wear on clutch = higher pedal. Not lower.

Oh, I never knew that, I was always under the impression it was the opposite, considering when my clutch begins to go it engages low and every new clutch i've installed it engages always at just about the very top .
