Urgent brake pipe needed for event

Hello sorry for English but we are passing through Germany and trying anything as it is an emergency. We are driving through the east side of Germany tonight and tomorrow and looking for a brake pipe for the rear right brake caliper which broke in our Volvo 240. As well as the hose that leads to it as we had to cut it and plug it to move forward. 

If anything we are hoping we could find a sped 240 around Hamburg/Bremen/east Germany where we can take it from and if anyone can help us at least point us to German websites with s parts that would also be appreciated thanks
