I totally re-did my entire Brake system five or six years back...new Wheel Cylinders all round, I think I got an NOS Master Cylinder, and new Flex Lines also of course.
None of these cost all that much, and if memory serve all these parts had a long application run, so, they are still easy to get.
You can get your Master Cylinder and wheel Cylinders 'Sleeved' in Stainless Steel or Brass...uhhhhh...I used to know the place which did this, and now I can mot remember their name.
They have a good reputation though and do very good work...you just send them your parts, they Sleeve them, and Hone them and send them back to you...you are good to go then with standard inards, since the Bores are all Factory Spec.
If their name pops into my poor sodden Heat dizzied head, I will post the info.
