[Fot] Supplier for Brake shoes for TR4

In Europe, the Datsun Z drums are rare. I use the aluminium drums from Moss Europe with the circumferential fins. These are much better than the radial finned drums.

It sure is, the center hole and stud holes require slight mods, but they will crack with hard use (racing). 
With frequent inspection you can catch the cracks early and monitor them. 
IF you can find OEM, I was looking awhile back and all that was available was repro.

The OEM Datsun Z finned aluminum drum is a nice retrofit. Several of the racers and street enthusiasts have installed them. The conversion doesn't require much modification. Lighter weight and cooler running that steel drums. Like Triumph parts, the original Z drum is what you want, not the aftermarket piece. Can be machined to 9.055" dia. Lot's of info in the FOT archive.

As the drum gets thinner/closer to the regrind limit, it will have a tendency to warp & get bell-shaped. 
I can't explain the difference in the cost between the drums, but in my experience the cheap drums/discs/etc are cheap for a reason, and not suitable for hard use.

Thanks to all who replied regarding the brake shoes. I’ve ordered a set from Ted Schumacher. The drums didn’t clean up with 0.025 removed from a side (final size 9.050). It would take another 0.020 on a side to clean the drums up making them 9.090 diameter. I think that is probably too much to take off but I’m not sure. We have a set of original drums on a street car rear axle that we could try and clean up or I can order some new ones. There seem to be two type of drums available; $27 ones and $58 ones (Moss). Nothing in the specs as to why the difference. Any input on drums would be appreciated.

The left rear brake shoe lining came off the shoe at Blackhawk Farms last weekend. I am looking for suppliers for brake shoes with riveted linings as the one that came off was a “glued” lining. I’d also like to specify the lining to use, the Carbotech linings whose pads we use and like on the front discs. I’m also open to any suggestions about what to use for the rear brake shoes. The above would just be my preference based on the latest experience. I see Revington has competition shoes with “Mintex 20” linings I think for about $120 a set which appear to be rivited. Anyone with experience with these brake shoes and linings? 
Thanks in advance for any info you can provide.
