Hi all, just need some opinions/advice if anyone else had same situ.

Handbrake shocking....adjusted the ratchet close to its max, still needs 7 clicks before beinging fully on, anything less, it would roll down a hill, I suspected poor/worn rear discs and pads, but had wheels off, and would say discs airnt that worn, just a little grooved on the inside, and pads only halfway thru there life. cars done 64k. is the parking brake fussy on having tip top discs etc, or is there another adjustment somewhere on the calipers that i can try?
