I have my Pathy for 2 years now, done 30k and already replaced discs and pads front and rear, including rear brake shoes.
Regarding braking performance I just miss some BAS ABS helper to engage brakes faster, but for almost 2 and a half tonne vehicle it stops quite normally.
But PARKING BRAKE was a joke before I changed rear discs and shoes, and is a joke after replacement. I can tighten it as much as I can pull the handle, I also adjusted pads properly, but still it's only good for leveled surfaces. On slight incline it simply does not hold, so I usually park near a tree or a building and turn wheels so that they touch the tree or wall.

Any advice on which shoes/discs you use, or what have you done to make parking brake more brake-like?
