Item Subject: Clutch slave cylinder leak - 87 Syncro
Hi All,
Sorry for this late response -- just now catching up on all the
mail. From my experience on wheel and master cylinders rebuilds (I've
done about 7 complete jobs), I would only rebuild the cylinder if
there were no signs of pitting. I have tried many times to save a few
bucks and tried honing the cylinder to remove the pits. I have never
successfully rebuilt a cylinder unless they were without pits to begin
with.
Almost all of them have pits because brake fluid attracts water from
the air. Since water is heavier than break fluid it tends to sit on
the bottom of the cylinder and corrode the machined surface.
Coincidentally, I am doing a rear brake job on my '85 Westy this
weekend. The cylinders are leaking and the break shoes, although they
have lots of lining left, are cracked (I have never seen this before).
And, you guessed it, I bought new wheel cylinders. I did not even
take them apart--it's wet in Oregon.
Hope I caught you in time.
Vince.

Vanatics,
Today I discovered a hydraulic fluid leak from the clutch slave
cylinder on my 1987 Syncro. Normally the van is in warm weather
(in Southern California), but I'm currently in Spokane Washington
where the temperature is below freezing. I suspect that the cold
weather has caused a seal (or seals) to contract and allow the
leak. Since I'm away from home, I'm not prepared to crawl around
in the snow under the van to repair it myself. I plan to take it
to a shop (likely the dealer) and see what they'll carge for repair.
Questions:
1. Does my premilinary diagnosis sound like the likely cause, or
is there something else more likely?
2. If it is a leaky seal, what needs to be done to repair it?
Rebuild by replacing wear components? Replace?
3. What is this repair likely to cost?
Thanks,
Jim Davis
