I just put them aside without really thinking about it. but I'd like to know proper part #. I'll see if I can find a "Made in..." on them. bet they're brazil nuts, I mean drums.
There were also some pads, I'll check for #. Busdepot sent me some that were smaller than T-1 pads, have no idea what they really go on.
311501615 - drum
pads??? But the ones I got were correct, they must have pulled your order wrong FROM THEIR VENDOR!!!!
As I found out, they just have all the stuff drop shipped like all those other Internet parts houses.
The original German drums were two part. They had the outer drum section made from a seprate piece...an wededto the flat center section on a jig. Very straight. Ray
Thanks, I checked out the drums. They have 3 stamps on the lip of the drum, (at about 10, 2 and 6 o'clock), but no 'made in' anywhere. Forgot to write the number/codes down, but they did have the VW logo

Those sound like the same ones I got, but on the inside they say made in Germany.
Bought some "rebuilt" 914 calipers from MOFOCO, luckily I also bought 2 rebuild kits from Bus Depot. The "rebuilt" calipers had some cheap flimsy seals and no piston retaining clip. BUT the calipers were sorta clean and shot with gold paint. The rebuild kits were German FAG so I wound up with some pretty nice calipers in the end for around $125.
Good Job DBus! Smart to open them up and put the FAG parts in!
Now you know what you really have! Did you have to check the piston and wall area to see it they spec out? I'll bet it would be sweet to go to a junk yard and check out the cars and the systems and then setup a sweet brake system up! Have to have all your measurement layed out! bill

LUCKILY the pistons and cylinders WERE SMOOTH, i took some fine emery cloth and toched them up.
Aaaaaaagh....do not tooth up the caliper walls. They must be smooth as a babys a*s. These do not have piston rings to break in. Although it won't hurt anything, the ttooth burnishes the piston. The piston rubs on the seals. Also, rough sides collect micro water bubbles. These should be polished unil smooth with like 1000 grit or better. Same goes.....especially...for a brake or clutch master cylinder. The hone marks on the walls....must be lapped out as they wear away at the seals. Ray
So how do you make sure the walls are true? Can you create a weak spot for fluid to pass by the seal or is that rare chance? I wonder if one of those white buffer stick cone polishers would work good with a extention?
Should you use polishing compound or valve grind compound? Ray is right about the hone marks being a problem I had my clutch slave fail because I didnt polish the walls! bill
