Excuse my ignorance.

Bike maintenance and understanding of components isn’t a strong point of mine.
Just got a 2022 Rise M10 and looking to change up to 4 pot brakes. Do I need to just swap out the calipers or does it need a whole brake set?
Thanks folks.

Whole set.

4 pot calipers need more oil to push the 4 pistons. 2 pot levers won't push enough oil as they are only designed to push 2 pistons.

What make and model of brake levers does it have because they might work fine with 4 piston calipers?

Deore M6100 levers and 2 pots calipers with 180mm rotors front and rear.

Will work fine with, for example, Shimano BR-M6120 calipers (is what I have on my Trek Rail). Works best with BH90 hose.

Great. Thanks for the help.

If your concern is stopping power, it might be cheaper to increase the size of the brake discs. Could be worth inviting comment on that.

220mm rotor for the front wheel, 203mm for the rear. (For my type of riding). New calliper spacers may be required to position the calliper brake pads correctly to the rotor(s).

The additional weight of an eMTB may require stronger brakes. Especially when everything is added up. Trail conditions, body weight, backpack, speed, weather etc.

It’s fun to go fast …but nice to slow down too.

What make and model calipers (2 piston?) are currently on the bike? Front and rear?

Deore M6100.

Deore M6100.

Then buy a pair of MT520 or M6120 calipers (same caliper, whichever is cheapest) should bolt straight in and will transform your brakes (usually pre-bled but you might need to do a top bleed). After that as @steve_sordy says go to larger rotors.

And no need for different levers?

No.

Shimano M6100 levers are ideally paired with MT520 or M6120 calipers.
