To read the press releases, the rewelding program is needed because some welds were less than thoroughly formed and are susceptible to breakage.
If the bad welds are left alone, the repeated stresses on the car frames (braking being one stress, but only one) will eventually lead to the welds coming apart. But as of this moment, none of the welds on any of the cars has failed.
If I understand the above, rewelding the frame won’t alter the braking mechanics. The creaking will still be there, although with wear on the joints and bogie bolsters it may change somehow over time. I don’t see a conspiracy theory here, although bad welds are a damning enough defect.
Unless there is retrofitting of snubbers or similar, the creaking will remain a defining characteristic of the car. Our children will wax poetic about the characteristic creaking when the Flexities go off to scrap in a couple of generations. Nobody said that PCC’s were meant to sound or ride the way they did, it’s just what we learned to love.
