Reconditioning Brake Lines
I'm glad others made the safety point.
I wouldn't hand bend a damn thing. Buy the kit, there's a few companies that make em, and it'll have all the armor and everything. The only bending I did on my car was UN-bending the straight section where they coiled it for shipping.
I DID get the stainless and had zero issues getting it to seal. I will say that the stainless that they use does get a thin film of rust on it but so do stockers.
And yes, DOT5 brake fluid is superior.
