XTR V-Brake "better" modulation than MT400 Disc brakes..

Background:
My 1998 26" MTB bike served me well over 21 years of use, full XTR 3 x 8 cogs.
I truly loved the XTR V-Brake modulation and 1-finger stopping ability, with it's cam mechanism.
However, the Mavic rims were going, other stuff, so it was time to put that steed aside and go modern.

Now, I "upgraded" to a Trek ProCaliber 9.6 29" with Shimano hydraulic disc, MT401 lever, MT400 caliper
7/19/2019, 2 months ago. This cost me over $2k, so I have high expectations for it.

I've been riding it 2-3-4 times a week, and it's brought new life into MTB riding for me again.

However..... after 2 months of riding I'm kinda dis-appointed at the Shimano MT400 disc brakes, simply they arent 1-finger stoppage like my old XTR v-brakes are/were.

Am I expecting too much?
I bought it from 14/Haggerty cycle and fitness, dropped off today explaining my dis-pleasure with the braking modulation and what can they do about, what my options are.

Appreciate insight from you guys on this.

Have you considered upgrading to XT or XTR brakes? The MT400 is an entry level version.

My old shimano xt disc brakes are outstanding in every aspect including modulation and stopping power. Way better than Formula r1 brakes on newer bike. Not familiar with MT400 Acera but maybe they don't work as well slx/xt/xtr or pads/compound can make a difference too.

Were the brakes ever bedded in properly? If not, you won't have good braking performance.

In my experience even low end Shimano brakes work well if set up right.

Thx all, guess the MT400 are just middle of the road and if I want 1-finger and excellent brake modulation I'll need to upgrade ... spend $500 seems.

Never realized how spoiled I was with those old school XTR v-brakes.

As I'm aging year-year, 56 now, I'd rather spend $500 and then save my hand/wrists from fatigue.

FWIW, I've got low end Shimano hydraulics on my single speed, and they stop the same as the XTs on my XC bike. They lack the modulation, but they definitely bite nicely.

I agree with Steve. Even the low end Shimano disc brakes should stop well. I would agree about not being bled, or set up right. Possibly fouled pads.

You need to get to at least the Deore level to get the SERVOWAVE.

All this really does is vary lever feel. You can still get really good brake bite without it.

I found a set of secondhand, but new in the box, Magura MT5s for $100. The 4-piston caliper up front works great, and the levers have a throw adjustment that allows me to brake to the point of lock-up with one finger.

But if he wants "better modulation", then perhaps an upgrade is in order?

Was pretty impressed by the Tektro HD-M745s that I put on my wife & son's bikes this summer. They're 4-piston and have more in common with the higher end TRP line than with what you'd normally expect from lower-end Tektro OEM brakes:

At only $60 / side on eBay, I wasn't able to find anything else that comes close until you start getting to more than double the price.

I feel you on the modulation of rim brakes vs lower level disc brakes.

I am running some shimano slx on my trail bike, for a reasonably priced brake ($200-250 for a set if you search hard enough) they modulate well and have decent power.

In general I prefer and have had better luck with the sram brakes, I like the guide RSC's, but they are pricier in comparison. The new trails aren't too bad IMO.

Update:
My brakes are all in proper condition per mechanic at bike store. Bike has 170 miles so brakes are set in

Yesterday I rode a procaliber 9.8, $5.5k bike on sale for $4.6k, it’s brakes Shimano XT. Immediately I noticed less finger pressure needed, better modulation.

Since braking is a 70/30 where balance biased to front for now I’m going to upgrade the front only.
Cut my costs in half.
Complete levers, calipers, and rotors as a set.
I’m leaning towards the XTR.
This may meet my needs.

So for $300 this is all I need right?

I really doubt you need to replace the rotor. I'd try with the one you already have. I don't know about the bracket. You may also be able to use what you already have, but I'm not that familiar with these brakes differences. If you do replace rotor make sure it's right type for your wheel (6-bolt or center lock).
