Thanks every body. So far Lynn Peterson has brought up Castrol LMA. I think I can get that locally too. Maybe I'll try that stuff. The AP Racing 550 brake fluid is only available from Race supply houses, and I think it's a bit overkill for a street car. I have to disassemble all the brake line connections from front to back and clean everything out so after that it will be a great time to introduce some brand new fluid. I have a brand new master cylinder and front calipers in good shape, the rear wheel cylinders may be good too I haven't checked them as of yet but they still worked fine before I began all the change overs.
