Hi Cliff!

Did you go with the fancy braided hoses or stay with the rubber hoses? I =
am thinking about switching over to the braded ones while I am at it but =
don=E2=80=99t know if the gain is worth the expense.

I had to change all the hoses - they all leaked after I switched to =
DOT5. I'd already rebuilt the calipers and cylinders and had new brake =
lines  I suppose I shouldn't had reused the hoses.

Randall,
Interesting. I have been running DOT3 in my TR4A since I got the car
drivable (about 2 years now) and only used DOT3 because there was a big
sticker on the side of the master cylinder telling me "USE ONLY DOT 3 =
BRAKE
FLUID OR WARRENTY IS VOID". I was wondering how big a PIA it would be to
flush out the DOT3 fluid and replace it with DOT5. I have read many =
posts on
this list where people have used DOT 5 with no issues so I am =
considering
changing over as I should probably replace the current fluid after 2 =
years
anyway.

Another contested question.  My experience is as Paul said, just =
"bleeding
through" will not remove all of the old brake fluid from the system.
However, I saw no ill effects from the small pockets of old fluid left =
over.
The DOT 5 will not mix with the old fluid, and is slightly less dense, =
so
you get little pockets of fluid in corners that don't get used (like the
base of the rear slave cylinders).  The DOT 5 also surrounds it, so it =
can't
promote corrosion (and I assume not absorb water or salt).

Main disadvantage seems to be that the remaining DOT 3/4 will suck all =
the
purple dye out of the DOT 5.
