Thank you for the new photo. The brake and idler pulley arm looks like a better fit in this picture compared to your other one because the brake pad is actually resting against the drive pulley here where your last photo it appears to miss by a mile. The only thing I could add is to check the brake/throttle pedal is all the way back (toward the seat) and not caught on anything. If it fitted before you changed the brake pad, it should still fit.
