Honda's official interval is 3 years regardless of mileage for brake fluid. Remember, we go off delivery date for that, not model year. It comes as maintenance minder 7 on the MID. The CVT fluid interval is recommended at 30k as well. You don't want to mess around with the CVT fluid interval trust me. The services that were recommended were appropriate.
The pricing depends on market. It's also possible this oil change was a B service? That might explain this added cost. I'll be honest, the B service is a waste on these cars under 50k if shes anywhere on the west coast. The caliper pins aren't as finicky as the older styles we had and there aren't many contact points on the pads to lube as the retention is a different style than previous as well. She could always opt for just a brake inspection instead but beware, the dealers definition of a brake inspection may vary. If I am inspecting brakes the calipers are coming off, pads measured, the pins are lubed, pad contacts are moly'd, and I push the piston in a bit to make sure it's free and to break internal debris buildup. Some dealers just poke their pad stick in, get a number and call it good. In short, B service is manufacturer defined (and is in manual as well as maint. minder), brake inspection is not.
Edit: I will add I hear most other auto manufacturers recommend brake fluid every 30k. It's not uncommon for pads to last 80k+. That's a long time to be leaving that fluid in your system. If I had a nickel for every time I opened a reservoir cap and it looked like a damn swap I'd have a lot of frickin nickels. I for one like preventative maintenance on my personal vehicles. Not corrective repair.
Honda Master Tech, going on year 14.
