[Healeys] Which brake fluid

I have used silicone for years without any problems....added  plus it does not attack paint..an accidental drop can wreck on a nice paint job. Have seen comments that silicone gives a spongey feel, but not that I noticed.

The BN2 is at the point where it is time to fill and bleed the new brake
system.  Now comes the time to decide whether to go with DOT 3/4 brake
fluid or try silicone.  Any recommendations,  advice or warnings on this
decision?

DOT4. If you want to try silicon you would have to rebuild your entire hydraulic circuit and fit all new rubber components. It may sometimes work without a rebuild or it may fail as DOT4 and DOT5 (silicon) are not compatible and do not mix.

What your life (and others) worth??

Sorry, did not read the question properly.

In a new system you have the choice obviously.

I would go for DOT4, which absorbs water, and change that every two years. That will get rid of any moisture getting into your system before it can do any harm. It also forces you to check the system when you replace the fluid. It is cheap and available anywhere.

The problem with silicon brake fluid is that it does not absorb water. Water will always enter the system because of condensation in the brake fluid reservoir. This moisture can than settle in the lower parts of the system and cause havoc unnoticed until it leaks.

In this instance I  agree with Kees.
The decision comes down to personal preference IMHO.

I'm with everyone else I've read so far; DOT 4. Simple and it works.

I have been using DOT 5 in my BJ8 for years.  Works fine for me.

I would like to say a few words on behalf of silicone brake fluid.It is non-hygroscopic (does not absorb moisture).It does not damage paint as do glycol fluids.
A newly rebuilt and scrupulously clean brake system filled with silicone fluid should outlast a system filled with glycol fluid by several times.
The military specifies Silicone brake fluid for a reason.?

Michael--

Both have pluses and minuses--I simply feel that DOT 3/4 has more of the
former and fewer of the latter than does silicone, but that's just me.
