I have not replaced the brushes, but will. I emailed coleparmer to make sure I'd get the correct parts. I just want to share this for other users to see, coleparmer has excellent customer service!
"The 07520-25 will require the brushes that are available as catalog number 07520-04. This is sold as set of 2, one for each side. You may also need the replacement caps as well that are available as catalog number 07520-03."
Both the brushes and caps shipped to my door is about $65. If this in fact works I will have spent <$200 for a used coleparmer masterflex pump with brand new brushes and caps!
Jose from coleparmer also attached the user manual for my specific pump, which will make parts replacement/maintenance MUCH easier for me!
