Type 3 Drum Brake Cyls
1500S - June 9th, 2010 at 08:52 PM
As most would know, early Type 3 drum brake slave cylinders are getting hard to get. Some turn up NOS on Fleabay from time to time but can be
expensive. I got caught a bit, only because I treated early Type 3 as being all the same with the slaves, forgetting that pre 64 had different
diameter drums and shorter slaves. What to do?? Don't keep looking for NOS for the 64 and later as you'll waste a lot of time. Get them sleeved
with stainless steel back to new without the worry of the dreaded rust coming back. If you have a lathe and the knowhow it's not a great deal. 316
stainless being preferred for corrosion resistance making sure that the surface finish is nice and fine off the lathe before the final hone after
assembly. Use a proper interference fit rather than rely on some chemical fixing compound........... it's only used as an excuse for a poor
machinist!!

Little things like this is pure entertainment compared with some of the stuff I still do Lee! I was back at the old work for a couple of days last
week and it took more time to find the "flexhone" than do the actual sleeve! No! I didn't do any foreign orders there as there is generally too
much interference from bloody apprentices! The store is in a bit of a mess and things seem to be getting scattered by "the new bloke" who has no
interest in the section. After I get the both sides done the master cyl will most likely get the same treatment. I have a kit to put into it but
haven't taken it off yet to see what the inside's like. It was NOS back in '91 but the back seal is definitely weeping. Just not enough use over
the years.

Well not fully Toby! As you are aware, out west of Sydney and no doubt, many other areas, it's difficult to find parts for our old cars especially
if you want them to conform to near original.
After wasting time scratching through dust and grime in semi darkness at an outer west "repairers" as well as at the local Windsor Brake and Clutch
repairer, it was back to the home workshop where I should have stayed in the first place . 
The 46 year old bleeder nipple was showing it's age along with being partly rusted in on the thread so in less time than it took to drive to
Riverstone, I now have a couple of stainless steel bleeders to do the job. Sure looks better than the old one!
