Thank you for the reply, Tom. I would love to delve into the thread if you started one! Right now, I have installed new Aisin masters of both brake and clutch and a new slave, but I kept the originals. I would like to find someone in our neck of the woods to do this to the originals, to be kept for spares. My wife doesn't understand why I keep some things after I have replaced them with new parts...lol, but then, there probably isn't many wives out there that do
. Look forward to any info you come up with if you start a thread on this...then again, even if there wasn't any real info in your thread, I would read it for the entertainment aspects...lol

Thanks Skip.
I seldom discuss my cruiser work with my
and I'm lucky that she's never crawled under the house to see all the stuff I have stored there..
Both my original clutch cylinders (master and slave) had the ASCO branding on them ... and I think this may have been a company that AISIN took over, or perhaps it's just an earlier brand that the same company used. (Whether AISIN or ASCO branded, these items look EXACTLY the same in every other respect from my experience.)
My logbook records are interestingly concerning my clutch hyydraulics.
I got 104,108kms/10yrs from the original ASCO units before I had to rekit them.
That covered another 100,000kms/7yrs and then I bought new AISIN units from Toyota (instead of rekitting).
The new AISIN units lasted only 35,000kms/7yrs before the fluid in the master turned black (signifying a lot of seal wear inside) and the rubber boot on the slave completely disintegrated. Needless to say, I wasn't impressed with these AISIN units!
In fact, that experience gave me such a lack of confidence in OEM that I went to Taiwanese aftermarket cylinders (and they've performed perfectly for the last 17,000/7yrs and still look/work like new).
So if I decide to revert back to running my original ASCO cylinders right now it'll be based purely on "cosmetics" or being bored with nothing better to do
. I want to run them when I think of those beautiful stainless bores... Trouble is, there's one aspect of the aftermarket gear I prefer, and that's the boot on the slave:
This is the Biggs unit with it's beautiful boot:
And this is the kit for recently-sleeved Asco showing what I class as an inferior boot:
The Biggs boot covers much more of the pushrod (with 3 bellows instead of just 2) and has a drain tube built in.
I'm now thinking the poor performance of my AISIN units may have been due to premature aging of all the rubber components from excessively-long shelf-storage at Toyota. That's all I can think of ... The boot on the slave just turned to shreds as shown here!!!!
So I hope you get a much better run than I did from your new AISIN gear Skip.
..I wonder if I've contradicted myself anywhere else as well.... (I've only got as far as rereading the first post.)
