..the only negative I've ever encountered with Dot 5 in our old cars is =
it does not lubricate the rubber as well as older fluids.
Synth and natural rubber also react differently ...as with everything =
with LBC's...   ymmv

When restoring my 3A in 2002, while the body was off the frame I =
replaced all the brake lines and hydraulic cylinders.  I learned about =
Dot 5 silicone based fluid from the List then and went with it. After 15 =
years of driving, the same brake system remains rock solid plus I never =
blistered paint with the occasional spill.  Doesn't silicone wear easier =
on rubber seals?
