How do copper automotive brake pipes compare to steel?
Copper is much better, however given the age of your vehicle the real question is, which is the cheapest solution. Copper is much more expensive, however, the price of steel replacements from the main dealer is likely to be far greater than the amount charged if the garage is an independent and forms and fits copper replacement pipes. Any dealership garage will charge you an extortionate amount, of course, whether they use steel or copper. Several years ago I owned a Citroen that required replacement of all the hydraulic pipes and the dealership quoted me over £700 just for supply. I got the pipes made up by an independent specialist for £140.
