Hello,

I have a question about the brake backing plate, and the brake drum.

Were they the same as the CJ3A or were they the same as the M606?

Did we get an initial production with a model like the CJ3A and was later replaced by a model that was also used on the M606?

Any help would be greatly appreciated.
Thank you
Alexandre

Were they the same as the CJ3A or were they the same as the M606?

Which backing plate & drum are you starting the comparison off with? You are asking us to compare CJ3A and M606 (CJ3B) drums and backing plates to something but you are not telling us which plate & drum.

i think he is meaning m38 brakes as thats the thread title and he continues his talking with the post

Alexandre,
I hope we are on the same page here:
