I sendt a mail at 1355, and 1413 Paul sendt his reply :
"Dear Bjørn-Are,
Thank you for your e-mail. Yes, this could be a kit I assembled and sold. The brake pads are also used on the new Santana PS10 and the old Peugeot J5 / Citroen C25 / Fiat Ducato van of a particular year.
You can also upgrade to the ventilated disc system by changing the discs and calipers.
If you have any questions please contact me.
Regards,
Paul Heystee"
This relieves my worries regarding the brakes, now I just have to find a local dealer of the mentioned carbrands.
Thanks alot for all suggestions and thoughts!
