Searching will lead you to tons of info.
Read the Ogre's Cave, linked at the top.
One thread here suggests this procedure to make the calipers self-adjust:
1. Set the e-brake (at least as far as you can).
2. Step firmly on the brake pedal and HOLD.
3. Release the e-brake.
4. Release the brake pedal.
You can also put a long needle nose vice grip onto the lever to manually activate it; see
https://gafiero.akroncdnr.c...oBrakeAdjustment.pdfThe service manual tells you, in short, to tighten the adjuster until either parking brake lever just lifts off the caliper body, then loosen it until the lever touches again.
It's fiddly, and I find requires much patience -- and an inspection mirror is handy to judge whether the lever has lifted yet (assuming you have the car on stands with the wheels off, vs are working on a lift.)
