sleeve M/C or buy new
 
Master cyl is leaking and running down inside the car. Didn't take it out yet so I don't know if it is pitted or not.

Do you think having it sleeved and then rebuilding it myself is better than buying new? I'm thinking once it's sleeved I'll probably never need to buy a new one, only rebuild it again if necessary.

I'm assuming Wagner is a reputable replacement. I can get a new Wagner MC49221 for $75 and free shipping.

New replacement would be my choice.

Sleeve a master cyl?
I can't imagine that to be a DIY kind of repair ...

This is a single-system m/c off of an old (66?) GM passenger car according to the buyer's guide.

I'm thinking that many of us (myself included) occasionally tend to buy "the best that money can buy" in the hope that it will last forever.

If we were to stand back and looks at it realistically, most our hobby cars will likely never be driven more than 50,000 miles in our remaining lifetime ... during ideal conditions to boot.

Here in Canada ... I think we pay a little more than you do in the US.

NAPA United 36242 (new) "joe retail" price is $181.79
NAPA TruStop 10-49204 (reman) is $54.79
At the reman price ... I seriously doubt that you could buy the m/c repair kit and a brake hone.

My advice:
Buy 2 remanufactured units ... one for the first 50 years (or 50,000 miles), the second one for the next 50. :D

Unless this is a show car/numbers matching/original survivor, etc., I'd be putting a dual pot MC on it, post-haste!

If you are bound to keep it a single reservoir, you can see if the bore is pitted. If not, a simple hone and rebuild kit (if you can still buy such a thing) would be my choice over a new or rebuilt unit unless cost is no factor.

I agree sleeving it is not usually a DIY repair; it requires precise fitting, the sleeve itself, and rebuild kit to boot.
