"... There is a newer Glycol Ester DOT5 ..."<br>
<br>
I think you're referring to 'DoT5.1' I also think it was
deliberately named so as to confuse the issue.<br>

I've used both. Currently prefer DOT4.<br>
<br>
Also everyone is speaking of DOT5 but there are now two different
DOT5s. The first is the older silicone based DOT5. There is a
newer Glycol Ester DOT5 that is compatible with DOT3 and DOT4. It
has a lower viscosity than the DOT3 and DOT4 so it works better in
some ABS systems. It also has a higher boiling point than DOT3 and
DOT4. Don't see an advantage in Healeys.<br>

<div dir="ltr">The best selling point for Dot 4 is you can mix
any Dot 4 or even Dot 3 if you need to fill up. As I
understand it with Dot 5 you should be careful to always use
the same brand to fill up if necessary.<br>
<br>
Also, neither Dot 5 not Dot 4 is great for sitting a long
time, Dot 4 absorbs water, Dot 5 will push any water down into
the components.<br>
<br>
Dot 4, if the car is not used regularly, needs to be flushed
every couple of years.<br>

<div>At this point in the restoration I have a completely
rebuilt brake system with all new components and
tubing. Now is the time to make the decision to use DOT
4 or Silicone. What's the consensus, if there is one?</div>
