John, I generally believe in the axiom, "don't fix it unless it is broken".
If your wheel cylinder/caliper/master cylinder seals are not leaking and the
hoses are not hardened, and your brake lines are not rusted, then I would
just refill with DOT3 or DOT4 fluid and bleed it. I have not done a
complete brake system overhaul for at least 25 years, but have replaced a
wheel cylinder, that is all.
Best, Mirek

Subject: [Healeys] Hydraulic system maintenance
Hello,
I am seeking the collective wisdom of my fellow Austin-Healey owners.
I restored my BT7 10 years ago and I drive it about 500 miles a year at the
most. In the last few years, while the pandemic was in progress, it has been
even less.
About a year ago I installed a remote clutch bleeder tube and I did not
tighten the bleed nipple sufficiently. As a result, fluid leaked out and I
need to bleed the air out of the clutch system.
However, I was wondering, because it has been ten years since the hydraulic
system was completely restored, if it would be wise to rebuild all of the
cylinders in the brake and clutch system.
Also, would it be wise to replace the front caliper flexible hoses and the
flexible hose under the jumper seats. It should be noted that all three
hoses do not seem to have hardened and there are not any other problems with
the hydraulic system other than having to bleed the clutch line because of
the air leak.
What are your thoughts?
John Spaur
