I use a reliable family garage for servicing my C180. On recent services and MoTs no reference was made to the offside brake pipes. However on its MoT last month it failed because of "excessive corrosion" to these pipes. I had them replaced, however I became more uncertain about it. It is 2009, it is relatively low mileage (51K) and it is stored in a dry garage. I then took it to one of the recommended garages in the Club Directory for an opinion. They were surprised that it needed doing - something they rarely do and only on older models. They confirmed that the work had been done. They observed that there was no evidence of any corrosion on other components (the near side pipes, suspension ...). I have brought all these and other points up with the garage but they insist it was corroded and have the sections of pipe to show me (I have no way of knowing whether they were mine). Does anyone have a view on this?
