I only dismantle the center console around handbrake, pulled cabels out, nip off right cabel from calipper (left one rusted and breake off earlyer), undo (break

) bolts for holding the cabels and that was it.
Hardest thing to reassemble was to get rubber collars into the holes above heat shield - took me an hour to do this

... but it was worth it.
Now i can park her on slopes, not only on level ground.
I don`t undestand why I would need to remove rear seats to do this, they are not obstructing you in any way.
PS
Price for both cebels - 50€
