C2 Master Cylinder

[John Lokay]

The master cylinder in my 1967 small block has the numbers 5455509 embossed on it side. Is this the original unit that came from the factory? Also, it appears from prior posts on the DB that White Post in Va. is the place to send it for restoration/resleeving? Thanks

John:

Some folks like Apple Hydraulics, some White Post Restorations. My '65 m/c was sleeved and otherwise restored by WPR. Beautiful job, reasonable price, quick turnaround.

John -

The 509 is the correct master cylinder, and should have "DC" stamped on the fly-cut machined surface at the front; White Post just sleeved/rebuilt mine a couple of months ago and did their usual outstanding job. When you send it in, tell them you want it painted black, not their standard gray.

John,
The last I heard was that White Post sleeves with brass. I prefer Stainless Steel. I use Imperial Machine in Lincoln NB. They're listed in Hemmings. Outstanding workmanship.

Re: C2 Master Cylinder

I guess there are two schools of thought in the sleeving "industry" - outfits like White Post and Apple Hydraulics apparently prefer boring the casting, pressing in a brass sleeve, and then machining/honing the I.D. of the brass sleeve to final dimension/surface finish. The outfits that do stainless steel bore the casting and press in the stainless sleeve without any further machining or finishing, and control the process well enough that the stainless sleeve doesn't have any distortions or "waves" along its length. In any event, I'm sure either process will outlast any of us.

White Post has the fastest turn around time in the hobby. Outstanding work. Ditto on the black finish.

Regarding sleeving material. If you will be driving the car with any regularity, brass is fine. If on the other hand, it will sit for indefinate periods of time, use stainless, which will prevent corrosion even if you store it for years.
