Wim, when the action brackets expand, the action spread also increases.
When I suspect this problem in a piano, I measure the action spread.  If it
is longer than the specs call for, I know the brackets have grown.  Reducing
the height sounds like a fun thing to try, but as others have said, it
should be temporary.  Please take extra precautions (gloves, face and body
protection) if you are using a bench grinder or similar power tool.  Just be
prepared for more metal flying off than you want.  I want to see you in
Grand Rapids without any new scars!
