We used to make brake pipes to pattern for any one that would visit our trade counter .... We had the skills and the latest equipment .... then one day a customer sued us for poor quality brake pipes after a brake failure and crash of his car .... This actually went to court !!
The driver never mentioned he was drunk when he crashed , and yes the brake pipes where broken as a result of the crash ... the Police report showed we where not to blame and we got our costs from the idiot, rich idiot.
We stopped doing them, the annual income did not make the risk worth while .... not our loss, just all the local guys doing their own maintenance ...
