In August I installed new: Ate shoes, Ate drums, VW springs and plates.
5 miles drive and OS drum was hot and NS was very hot. Could not touch NS drum it was so hot. Took the drum off and everything was Ok. Another 8 miles drive NS was still extremely hot, took it off and everything was Ok. In total the drum was in and out three times.
I have searched the internet and it was an advice how to self-position the shoes relative to the drum: “go forward and brake than go in reverse and brake”. I have repeated this four times and done 8 miles, the drums were just warm.
The clearance between the new Ate drum and Ate shoes is tiny and a small misalignment could be the reason of the heating.
Regards.
