For my TB 20 I’m looking for 2 Brake Disk. They can be used.
Is there someone could help.
Best regards Thomas
These are standard parts from Cleveland who make most wheels used in light GA. You can get them from any normal parts supplier. Not expensive.
They are listed as Cleveland part number 164-01900, same as on Piper Comanches etc. They’re about $150 USD each.
If by chance you need them for some unusual reason where condition is unimportant as per your mention of used parts, I see a set on ebay at the moment for $80 each 
I would not buy used disks as replacements for use on an airworthy plane, that would really be plumbing the depths of cheapness!
