We love just about every British sportscar that was built from 1955-1967 (and we’re easily seduced by earlier and later cars too). But given that we are so stuck in the past, we see more systems aging out with each passing year. None of our bits are getting any younger.
This week, brake lines were in focus while working on a car that had been sitting for the past 20 or so years (like a lot of our favorite sportscars). And when the steel brake lines in this particular car fractured the minute we removed them from the vehicle, we had a chance to reflect anew on the (often) fragile fluid link between master cylinder and wheel.

The lines above broke at the nipples without persuasion. These are the original lines, and you can see deep pits and thin walls at the location of the fracture. We have talked previously about moisture in the master cylinder… it not only attacks the cylinder bores, but can damage the steel brake lines as well.
