Not unexpected for a 30 year old vehicle. Especially if you live in an area that salts the roads in the winter. Most simple solution is for shop to replace it with new steel tubing. There’s another type of brake tubing available, copper-nickel alloy, something you might consider, said to last longer. Brake tubing of either type must be installed correctly, using a double flare technique. Make sure shop does the job correctly. ---

Ah, appears to be the same problem that Professor Godel ran up against … lol … > **[Gödel's completeness theorem](https://en.wikipedia.org/wiki/G%C3%B6del%27s_completeness_theorem)** > > Gödel's completeness theorem is a fundamental theorem in mathematical logic that establishes a correspondence between semantic truth and syntactic provability in first-order logic. > The completeness theorem applies to any first-order theory: If T is such a theory, and φ is a sentence (in the same language) and every model of T is a model of φ, then there is a (first-order) proof of φ using the statements of T as axioms. One sometimes says this as "anything universally true is provable". This does... I wonder how to get that umlaut symbol above the “o”? Nothing is simple these days. ---

> [@ArtTenbrink](#): > > Right rear brake hydraulic tubing needs replacement If it is rusted out and leaking then the rest of them are probably not far behind… May be best to replace them all… Might even have to replace the wheel cylinders if the bleeder screw are seized and or calipers and hoses, all depends on the extent of the rust… Some vendors sell complete lines as kits and some have to be hand bent, labor will be much higher if hand forming the lines…
