Hydraulic disc brakes after period of no use

My son has a MTB (a little nicer than entry-level Jamis) that has hydraulic discs. We got the bike in 2020, and he only rode it occasionally up til about a year and 1/2 ago, and hasn't touched it since. "Light use" would be an understatement. He's interested in getting back out there, but I'm strictly a rim brake and mechanical disc guy on my bikes, and have no experience with hydraulic brake maintenance. I've examined everything I can--pads, etc, and as expected that stuff is fine--like new really. The pads are barely worn. The brakes appear function fine--the feel as they did when it was new. But do we need to bleed the brakes after this long a period of no use?

Bikes: Too many. Giant Trance X 29, Surly Midnight Special get the most time.

They’re probably fine. If they feel bad or have significantly uneven bite point then consider a bleed.

No just get out and ride! Don’t worry about bleeding the system until you have a reason to. It should be good for a number of years and many miles.

Generally I just pump the brakes a few times and everything is good. The only time I would consider if you are using DOT fluid like most SRAM brakes but if mineral oil you should be fine. If the bike was stored upside down which I would hope not then air could be introduced to the system but usually a couple pumps and all is good.

This is simple...Ride downhill really fast. If the brakes don't slow you down, and you crash and die, you'll know the brakes need to be bled.

Only if they feel spongy.

I have a bike with hydraulic disc brakes and they need several pumps in the spring, after a winter off, before the function as actual brakes again.
