It is really hard to tell from the pics if they are salvagable or not. Maybe he'll let you take them & clean them up before you hand over the cash or at least have someone look at them in person? I guess it depends on the price wether you take a chance or not. _________________ Mic

Especially the first drum looks really bad as the surface were the rim should rest is so corroded that it is not even flat anymore but I dont know. I never dealt with Porsche brakes before. _________________ ----------(VW)----------

Mr. Nize:
The issues you should be worried about are the splines and the condition and thickness of the steel liners. The spiffiest drums in the world are worthless without good splines and liners. And judging by the poor fotos, it seems what you see is evidence of serious corrosion of the steel parts (splines), so that I, for one, would expect the worst of the steel liners.
Unless the seller provides clear close-ups of the splines and good shots (and actual measurements) of the liners, I figure its a safe bet you'll regret the purchase.
Just one guy's opinion. _________________ Keep 'em flying...

Mr Szabo is correct in saying look carefully at the splines. Those last 2 photo's seem to show them in poor condition. Looks like they have been rattling around a bit to me. The inside of the drum as expected looks better than the outside and the liners although rusty might be okay. Again if the splines are defective then the roundness value of the liner might also be all over the place.
I would look for others, I think.

Good used A or B brake drums, in all areas excepting, or so I've heard, Cali, are hard to find.
It's a nasty process called "bi-metal corrosion" meaning that cast iron and (forged) aluminum don't stay friends forever. That creates some swelling between drum and lining and the dreaded "hot spots" that won't ever go away.
The only solution is to rebuild those core drums that are worth doing by one of the few-and-far-between persons who can handle that task of doing whatever it takes to make them safe and strong...and worth doing at all
(Call Brad Ripley in Reno...Stoddard NLA LLC.... for his advice.)
Those shown are hardly good cores for resplining and relining with those wheel-mounting surfaces being that corroded. A machinist could turn that down and create a plate as a substitute, but the price better be REALLY cheap with all the work anticipated from even those fuzzy pictures.

There are a lot of them for sale on Ebay. I just searched for 'drum puller" and this came up (along with about 60 other listings):
http://www.ebay.com/itm/Studebaker-Craftsman-Brake...mp;vxp=mtr
I have one similar to the one above and it works great. There are a lot of them listed so all you have to do is decide on quality and what you are willing to pay. |

Read through this thread. http://www.porsche356registry.org/356talk/1/35875.html
If you do get a puller you might need to make an adapter plate to fit the 5x205 (wide five) that is on the 356. Not a big deal but read the thread above first for some other hints. _________________ Mic

Once upon a time ilco made a bolt grip puller type of large scale drum puller. I own one,it works fantastic but is brutal. I use a chain wrench vice grip on it to dial it in for play I want to allow. More important,I think I have some extras of these drums,conditions are almost the same.Nize, if you think they might help you,you can have them. They do no good sitting around my place. |

first... check the splines... if they are worn... don't use the drums. IF they are ok... then proceed.
somewhere... I can't find it right now... is the correct minimum thickness for the liner on these things. measure that and if the liner is thick enough then step two would be to find that figure... and measure.
Next if they are useable... blast them with a "pressure washer" or scrub them with a really stiff brush and water until they are clean.
Next take them to the brake shop and have them put on the drum turning machine... to see how out of round they are...only do the absolute bare minimum to get them round and "faced".
then I'd either walnut shell or soda blast them. Don't glass bead or sandblast them... too much pitting will result. don't blast the "turned" surface.
after the blasting... get some 0000 steel wool and WD40... spray the exterior o the drum with WD40 and polish with the 0000 steel wool. this will get the drums looking pretty good. I'd spend an hour or two on each drum with this method until you are pretty sure you can't get any more out of it.
Stoddard sells the redone brake shoes and other bits You will need to turn in your core brake shoes. There are 4 different types of 356 brake shoe... so take a few photos of what yours look like... and make sure you get the exact replacements. _________________ some cars

Looking at the hole thru the drum next to the liner can also be a giveaway...if the hole is a circle or more.....gone. If some of the circle is obscured, there's hope for the liner. _________________ Looking for SP Kadron manifolds...please !!

I see how old this original post is, but if anyone else has questions regarding deteriorated/damaged brake drums, I would recommend contacting Martin Willis at http://www.mwthemachineshop.com in Colorado Springs. Check out his website. He is very helpful, knowledgeable, and easy to communicate with. I was very satisfied with the drum re-lining he did for me.

Even with the age of this thread, I gotta second the last comment regarding Martin Willis at the machine shop in Colorado Springs. Guy is kinda hard to deal with and you may find him on the pricey side but no doubt he can save old Porsche drums by installing quality brand new liners the way oem did them. He also has new lined shoes arched to perfectly match you fresh new lined drums. |

There is a guy in WI or IL that rebuilds these. I met him at Road America a few years ago and talked with him a bit. Convinced me he knows his stuff.
I’ll have to find his card, I know I have it and will post his info. |
