[CAUT] pedal squeal

[kpiano]

Isolate the sound to those brackets that hold the rod or the lift felts. If it's the lift felts I would 
try TFL 50 spray stuff. Replace the felt if the bracket is making the squeal. The pressure fron 
the dampers may be pressuring the rod backagainst the action rail.
