Not sure what you are asking.
The needle bearing just come out with a sharp tool.
Best to take the assembly out of the car.
Don't loose them.
Clean, put grease in to hold them in place while putting the thing back in with the shaft.
The bushing on the brake peddle is just lubed and reused if good.
Is it bad for something?
I want to detach the brake pedal arm from the pedal housing so that I can replace that plastic bushing with one of the metal ones valiantone has. I want to get the brake pedal apart like in your second picture. How did you do that? Thanks.
