Can anyone source a master cylinder for 69 w/power disc brakes?

If the only problem with yours is the grove of rust in the bore, you can have them resleeved with a stainless sleeve which will almost prevent rust from forming again.  That is what I am going to do with the core I just got.  Have it stainless sleeved and then have it rebuilt and it should be good for life, just like my 4 piston calipers.

Sounds like I'll be calling my local machine shop on Monday to see what they charge to sleeve my M/C. The M/C is too important to NOT have it right.

Crap......

White Post Restorations in VA is supposedly the best for this.....  Their website is down right now...

Basically, any brake place that does calipers and master cylinders should be able to sleeve it without any problems.  I know a place up in NY called Apple Hydraulics that I got a rebuilt kit from to do my 4 piston calipers.

Anyone know if these sleeves are predrilled with the correct holes for the reservoir or does the shop drill them before they put the sleeve in???

[resq302]

I don't know.  I would assume that they press the sleeve in and then drill the holes in the appropriate location going down from the reservoir to make sure the holes get into the correct location.  I do know that we had a master cyl sleeved for our 70 El camino by a company (forget which name) and when we installed it, it would push fluid throug the lines but not return it to the reservoir.  Aparently, they claim they had the sleeve off center in the bore slightly allowing the one hole to be in the right location but not the return.

[Mfr426]

That would mean that that particular sleeve was predrilled before it was pressed in. I would think that would be the way to go. Obviously getting the sleeve lined up is paramount.

I'm eager to talk to a machine shop tomorrow.

[resq302]

Personally, I would think that drilling it after wards, meaning once it is pressed in, guarantees that you get the holes in the right location.  Plus it also cleans out the holes to the reservoir of any loose debris.

[Mfr426]

We'll find out tomorrow...

[Mfr426]

I just looked at the bore and the holes and without a doubt your are correct and it would be far easier to press in the sleeve and then drill the holes. That makes it look like a fairly simple job.

I tried Rock Auto for one of the 101475's but they apparently sourced theirs from Cardone and no longer have any either.  Cardone is apparently trimming their list of available parts down because this same thing happened with the power boosters.  If there is anything you think you might need from them, I would order it now.  No telling how much longer they will have it.  These old parts are the ones being dumped.  I wouldn't be surprised if this same thing doesn't start happening with a lot of the parts we buy for 69 chargers.

Well persistance has paid off once again! After about 5 failed attempts at NAPA to get the correct MC (and the last one was full of rust from sitting on the shelf for so long), I finally hit the jackpot yesterday! On a whim I went to a local National Auto Parts. Now keep in mind that I have had an aversion to these folks for many years (the place just seemed out of touch compared to the bigger chains). Anyway, the guy "had one" of the MCs that I needed and ordered it for me on Friday. I fully expected it to be wrong or have the lines on the wrong side when it arrived but when he got it yesterday it was 100% CORRECT!!!! Additionally it was a nice rebuilt. I disassembled it when I got home and it the cylinder was clean and machined nicely!

So, the lesson learned is that as our car's parts become more difficult to source, we'll need to look under every rock that you can find. I never thought that National, with their lame dialup modem for parts ordering, could source such an item but sure enough, they did!

Thanks for all the help in this adventure. This week I'll pull the booster for a repaint and reassemble the brakes. Perfect timing as this week it looks like we may hit 70!!!!

Great Mike!  Keep us updated on the progress

[resq302]

Mike,

That is how I found the correct one for my car last year.  A small shop called REN Auto Parts in Denville, NJ was able to get me one.  I tried getting a spare from them this year but they kept coming through with the Cardone reman'd ones (like the one I got last year) only this had the ports on the fender side and for some reason, they cross drilled new holes and installed tubes onto the engine side.  Not only did it look like a frankenstein job, I could almost guarantee that it would have probably leaked.  So not only did they destroy what was once a perfectly good HEMI casting, they made it look like crap at the same time.  That was the whole thing that got me into picking up spare parts of the hard to find items for our cars.  Now I am on the look out for another "spare" hemi style brake booster just to have in case mine ever craps out and I am going to a show the next day or so.  I have 3 extra 4 piston calipers, one of which is rebuilt and ready to get installed should I have a problem.  The other two are in despirate need of rebuilding as the pistons are frozen into the bores.  Definitely a candidate for a sleeve job in them.

[Mfr426]

Brian, I know EXACTLY the Frankenstein job that you are referring to. They did the same with the last MC that I retured for being rusted internally. It had "ears" on all sides and would have looked like hell.

Funny, the core deposit on the correct one was $15.00. I will be keeping my core for a future sleeve job as well should I need it.

[resq302]

Same thing I did.  For $15, it is cheap insurance just to have another one in your possession.

The saga of the master cylinders continues.  I reported in an earlier post that RockAuto didn't have the 10-1475 master.  That was based on me ordering two they said they had and getting an e-mail saying sorry---no longer available from mfr.  Well, I figured that was it.  Based on an earlier post, I called my friendly National Auto Parts store in Knoxville, TN (we don't have one in Chattanooga) and they checked and said they had one in their system---and only one.  I said fine, order it.  Then the next day, I get a second e-mail from RockAuto saying they were shipping two 10-1475's.  What the hey?  So I figured I would just lay low and see what they sent.  Well, one was correct and one had the extra ears on the left side.  I sent that one back.  Then the one from National came and it was correct.  So I have one to use in the car and one for a spare.  When I called Rockauto to send the "bad" one back, I asked the guy if they had any more and he said no.  Also, the National guy got the good one out of his Florida warehouse.  Said it was the last one listed on their system.  There still may be some out there in mom and pop stores----who knows.  But what a crazy turn of events.  As Mfr426 says, sometimes persistance really does pay off.

I tried ordering one from Rock Auto as well back in January......they called me and said they couldnt get one....cool that you got one from them

[Mfr426]

Sounds like you guys made out OK then too? Frankly, I'm surprised that we've been able to get these period!
