I dont know how to thank you. Your diagnosis is completely correct. This is my father's vehicle and hasnt gotten my attention since i was 18 yrs old and lived at home. I guess i have become too used to my american Z28 and forgotten what real automotive engineering is all about! The parking brake is doing almost nothing and i suspect those shose are far overdue for a change. In fact, i vaguely remember the e-brake was almost useless years ago when i used to drive the car. Thanks so much for your time and attention to my problem.
