Regarding Triton 5550I pump failure, the Salamander RSP 50 fits in its place without any piping changes, using the same connections as you use on the Triton 5550I pump. Its also much quieter
Triton T550I motor brushes are 5x8x15.5mm carbon blocks available on Amazon and many places . Need to completely dismantle the pump to put new brushes in, so need plumbing , electrical and mechanical skills
