I used to pull on handbrake to hard, one day the handbrake felt very slack, a friend adjusted it a few times, even took back wheel off and did something, think he said caliper was sticking or something, also brake disc was scored.
handbrake stayed firm for about 3 days, then went slack again, even adjusted it inside the car but after a few days it became slack again , also it took about 5 - 7 clicks just to secure the car from rolling.
even after replacing rear brake pads/discs the parking brake felt slack and took about 5 - 7 clicks to hold the car on modest hills.
also the new brake disc on the same side soon became scored like the previous one.
I've just gone out and used a ratchet and extension and got several turns but stopped before risking over tightening , the car is holding better now on around 2 - 3 clicks but am just hoping it will remain under tension and not go slack again, will have to wait and see.

if not do you have any ideas as to what could be the problem ?


thanks all and as always much appreciated
