<p class=MsoPlainText><font size=2 color=black face="Courier New"><span
style='font-size:10.0pt;color:black'>I’ve been using DOT 5 for some 30
years; and IMO the advantages far outweigh the disadvantages on the
street. (Racing is quite another matter, though, I wouldn’t use it in
a race-only car.)<o:p></o:p></span></font></p>

<p class=MsoPlainText><font size=2 color=black face="Courier New"><span
style='font-size:10.0pt;color:black'>IMO, there is something to be said for
doing the whole megillah when converting: completely disassemble the system,
replace all rubber components, clean all the lines, cylinders etc.
However, I’ve converted several times now by just bleeding through until
only clean silicone fluid comes out; and it still works out OK. It just
seems to take awhile before you get the full advantage of the DOT 5. It’s
almost like exposure to DOT 3/4 starts a slow deterioration process that doesn’t
stop (or may even accelerate in some cases) after converting to DOT 5. If
you don’t change the seals now, they’ll be leaking eventually and
you can change them then. By way of contrast, I am still using the brake
calipers I rebuilt some 30 years ago and have never seen DOT 3/4. Got to
be well over 200,000 miles on them; and the bleed screws aren’t even
stuck!<o:p></o:p></span></font></p>

<p class=MsoPlainText><font size=2 color=black face="Courier New"><span
style='font-size:10.0pt;color:black'>I also (eventually) switched to the “braided
SS” soft lines and copper alloy (aka Cunifer) hard lines.<o:p></o:p></span></font></p>

<p class=MsoPlainText><font size=2 color=black face="Courier New"><span
style='font-size:10.0pt;color:black'>As far as DOT 3 vs DOT 4; I don’t
think it makes much difference. DOT 4 is just like DOT 3 in that it will
eat paint, absorb water (and salt!), turn corrosive over time and so on.
This is an extreme example, but seems typical to me of the kind of damage you
can expect from DOT 3 or 4 if it doesn’t get changed.<o:p></o:p></span></font></p>

something starts to leak and then the fluid gets changed while fixing the
