John & John:
I have made the switch as well, and I am pretty happy with it.
I made the switch when I did my frame off, and rebuilt the front
and rear brakes, and replaced the hard lines. My soft lines were not
replaced, likewise for the various unions. I got a little bit of DOT 4
out when I purged, but not much. What I did notice is that my mi-tee-vac
(sp?) was not a satisfactory way to bleed things. The DOT 5 wants to
retain air, and I could not get clear fluid when using the vacuum bleed
technique. On the other hand, bleeding t the old fashioned way was cake.
Between the new cupronickel brake lines, and DOT 5 I don't think
I will need to worry about rust (my old caliper pistons were trash by
the time I got them out - deeply pitted and very rusty). That and the
freedom from paint damage make me very happy I made the switch. Besides,
it is soooo cool to have that purple MC reservoir. Worth the price of
admission just for that.
I did not get one of my fittings tight enough, and it dripped
brake fluid on my fresh paint for a couple of weeks before I noticed. I
wiped it up and the paint was still like new. Ahhh! So satisfying.

John,
Regarding the removal of the old brake fluid on a change over to Dot5, I
did
this 1 1/2 yrs ago and I still have some residue show up in my brake
reservoir. I completely rebuilt the front calipers, back wheel
cylinders,
and master cylinder. I also replaced the front rubber lines. I tried
to
flush the lines using Dot5, but obviously did not get it all. On the
other
hand, I have not seen any negative effect of the residue and I feel much
better about the benefits of using Dot5.
I use my 74 a lot as a street driver and take long trips with
confidence.
