No big problems. The pads sat a little tight in the calipers so i removed som paint at the ends of the pads to make them move more freely:
The rest was straight forward. I had the brake and cluthc fluid changed to fresh Castrol DOT4. Thanks to my girlfriend for working the pedals

The padmaterial was so brittle that it had loosened from the backing plate.
No more Greenstuff for me..
