Brake pedal keeps going down while at a stop

2007 Lexus ES350 155K miles

While stopped at an intersection holding the brake pedal, it sinks some but not all the way to the floor.  Is the master cylinder failing?  If it needs replacing, what brand should I use and who should I buy it from?  How do I bleed the brakes myself?  Thanks.
