Who rebuilt my rear brake, focin lazy previous owner

[joebloggs]

Had split the rear caliper prior to painting as suggested by someone on here, after looking at the pistons I noticed one was further out than the other, and after trying to move it I understood why, seized rear caliper syndrome. On the bench, gently rotating said piston reviled only one seal each side, someone obviously didn't think two seals were required  :wall

Tbh the pistons look fine and hopefully the remaining seal will be OK to reuse, just hope I can source some outer seals (dust?)
