[Healeys] Brake fluid

Hi,

My brake fluid reservoir also had a leak. I took the fittings to a local
hydraulic supply shop and got the right size sealing washers for less than
$2.

Ira's story is a great reason to use DOT 5 silicone brake fluid. It is not
a matter of if our cars will leak, but when. DOT 5 does not harm paint and
is not hygroscopic, which is a major benefit for cars that are not driven
regularly.

Best regards,
Harold
