I should have mentioned it in my post, but i had the shoes replaced... still no good.
then started reading on here and backed off the cable adjustment then adjusted the rear pads first with wheels off and just slipping the drum off the, with the wheels on and through the gromet... adjusted them untill i could turn them by hand and they spun free for 2 full turns then stopped.
re tighten the cable back up and really do notice the difference. they improved 10x to what they were, where it used to hold almost all the way up it now holds on 3 clicks.
its just really steep, i mean real steep hills that it doesnt hold... and its only on the nose up the hill, it holds if my hose is down the hill.
and my ute has a fair bit of extra weight, canpoy, drawers, long range tank, steel bar, winch, dual batt, scrub bars, rock sliders, rear bar, rack on canopy. but still there made to take weight.
im just thinking if it hold going down the hill there must be a way to make it hold going up the hill.
