I have been told by my local Porsche dealer that the four short metal brake pipes which connect to the brake calipers are corroded and need replaced. They have quoted a price of over £400 for the work. I can do this myself for a fraction of the cost, but am unsure of the type of pipe I can use - copper / cupro-nickel / stainless steel. Can anybody help with comprehensive data on what I need, including pipe size and fitting thread size, and if there are any hidden pitfalls in doing the job? Also, any recommended supplier or will anybody on Amazon or ebay suffice?
Thanks for any help provid
