Hi gang, 
I have been using the repop Datsun aluminum drums on my TR3. They are from 
Centric. There are two choices, standard and premium. I have ordered two 
premium pairs and machined them to fit the TR backing plates, hubs and wheel 
studs. 
I replaced the first set because I damaged the fins on one and decided to 
replace both in order to keep even wear. 
The first set had been working fine with no signs of unusual wear or cracking. 
I think they had 8 race events and a couple thousand miles on them. 
I can't imagine what is different between the standard and premium, besides 
price. I could not get any information of that topic from any supplier, 
including whether they were cast iron or aluminum. 
For the premium price, which might have been $50 or $60 a piece, it's worth 
changing them as soon as a problem arrises, even if it's every couple of 
seasons. 
I would definitely go for the UK units that Marcel uses, but I think they are 
very expensive and shipping is too. I think they were over $300 a piece if I 
remember correctly. 
I never go cheap, but do try to be rational and sensible. 
I have been using the same set of standard shoes from SBS all along. I think 
they are glued on.

?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.
