Hi KiwiJochen
At Syd BMW they always change the pads and disc at the same time. In parts alone its costing $1250. The pads have eaten into the disc, the boys say always replace the discs with pads. The car has only done 28k too
From an estimate on the phone 2k. Dont forget there hr rate is $165
I knew this was going to happen anyway, it happens on all german cars the brakes cost money when they wear.
Cheers
Bourdo
