I guess I will spend the day pulling the brake drum off to alleviate by dragging brake issue......what fun
It might be worth having a new
wheel cylinder (CW15953) handy to pop in as this rusting up internally and seizing up is a common fault if the car has not been subject to two yearly fluid changes which is what most of us do on the 4 wheelers.
I used
this outfit when I rebuilt the brakes on my 1999 Plus 8 eight years ago and they are good quality and still going strong.
Good luck.
