Master cylinder

[63409]

I'm trying to identify this master cylinder I took off of my 63 SS Impala

 

[Phil Reed]

It's a correct 63 Tom.

 

[63409]

Power brake or non power brake master cylinder ?

Power brake or non power brake master cylinder ?

I believe both the same

 

[63409]

Something tells me that there was a notch somewhere for 63 power brake master cylinder.

I cleaned it and striped the Orange paint. What is the date for 171 . The built date for my 63 Impala is September of 62.


It also has the small writing on the cap.

Don't know if this is correct but looks like it may be a julian date code of June 21 or so.

Thanks ,is there a way to tell if it's June 1962 for 63 model year because my car was built Sept 1962 for the 63 model year.

Cecil may be able to shed some light on that.

I don't have any documentation on those master cylinders but I see the CFD wagon wheel on that one and since our engines were changed to CFD and julian dates in May or June 62, I would think the MC would have also. That would make it for 63 production.
I have a few of those on the shelf but never paid much attention to them other than to look for the 63 Corvette part number and 7/8" cast bore.

Ok thanks

I can get you an answer this week. Verne will know but he's busy this weekend helping with the judging at the MCACN show in Chicago

Don't pass by those lowly junk yard Corvairs, I think they used the same m/c that the Corvette used.
And, the Corvette vendors are repopping the M/C lids.
Oh and Pontiacs used this same style M/C in 62 and 63

Seems like I recall PB masters were also 7/8.

So did Oldsmobile.
