[Roadsters] braking issue

Mike,

OK, thanks.  I don't recall ever shaking the bottle, and we do pour
carefully, because I just use the M/C reservoirs, and it is easy to overfill
them if one is not careful.

I originally drained the DOT3 fluid, flushed the
system thoroughly with denatured alcohol (which dissolves brake fluid), then
drained the alcohol, filled the system with DOT5 and flushed DOT5 through
until I was confident I had all the alcohol out.  Bled the brake/clutch and
never had a problem.  I probably wasted a quart of DOT5 in the process, but
considered it worthwhile.

Gary

I have found that it
is harder to bleed BECAUSE it is silicone based and non-hygroscopic, (its
blessing and perhaps its curse) if it is not handled carefully and allowed to
be shaken up the air bubbles are hard to disburse and takes a long time to
settle out to the bottom.  If poured carefully, and not shaken in the
container, then it probably bleeds just fine.  It IS better - no argument here
- but the cost, and trouble with totally flushing the old system before the
change just never made it my choice.  Glad you like it, and I may switch
someday myself.

Mike,

Why is it harder to get air out of
the system with DOT5 fluid?  I have never had a problem with my '66.

I use
silicone fluid because it is non-hygroscopic, so brake parts wetted with DOT5
don't corrode.  And the rubber parts last longer.

For what it is worth,
I have a '66 with a single master cylinder and it stops
on a dime.  In fact it
stops better then the '69 I used to have and I re-did
the brakes on both.  The
reason for the dual master cylinder is for safety, so
you do not loose all 4
wheels upon failure, and that is a good thing, but I do
not believe it helped
the stopping power at all.  Both cars will stop very
well when everything is
working properly.

I know you
 are firm on using DOT 5,
and that is OK, but
you do know it is much harder to get all air out of the
system. Unless you are
racing, I do not see the
 need, but then I think stock
systems work best with
OEM fluids and parts.
