I always replace the bleeder resistors with more-modern carbon-film or metal-film resistors. The carbon-composition resistors in the picture were the favorite choice 50 years ago, but they have a bad habit of drifting, changing resistance value. This could cause premature failure of a filter cap. When three of them are in series, you really want the DC voltage to be divided equally across all three. If one of them gets a "share" that's over 450 Volts bad things can happen. New bleeder resistors are cheap insurance.
