Nope!  I have never seen them before.  Therefore, I went ahead and ordered a set off of the Aliexpress Link you provided.   $108 after coins and coupons.   They seem worth a try.

Let us know how they work out. 

Tijoe, You've gotten most of the brakes available from AliEx, which ones are the best so far in your opinion? How would you rate them against common Sram or Shimano stuff?

They're very light for a 4 pot brake (edit: I've just noticed they're not including the weight of the hose or pads). I'm wondering where the compromises have been made considering how cheap they are too.

(LOL)  Before venturing into hydraulic brakes sold through Aliexpress, all I rode was Scumano XT 2 piston brakes.  XTs were all I knew.  My focus was primarily on the IIIPro 4-piston brakes because they were affordable and appeared to be well made.  On my FS Mtn bike, the IIIPros have worked well, but a lot fewer miles than on my hardtail/bikepacker where I have had non-stop problems with the IIIPros. I ran a set of ZTTO M840s for a while, and they were OK, but the bike they are on developed a crack in the frame, so there they sit. 

I guess my baseline is I want brakes where I don't have to think about them, or complain about them, or adjust them.   I just want to ride them and swap pads when needed.   (The IIIPros haven't met this criteria.)

Then I started thinking.   The 2-piston Wheeltop EDS calipers that came with my EDS TX kit, have been quietly stopping my gravel bike for thousands of miles and I still haven't had to replace the pads.   (I did have problems with the levers locking up, different story 1+ years ago) (This wasn't a caliper problem.)   

Therefore, these new Wheeltop brakes might be a lot better than The IIIPros.  (Crap shoot?)

I believe I posted elsewhere, that my focus is to find a set of affordable/on-sale set of Hope Tech E4 or V4 brakes.   I need foolproof dependable brakes on my hardtail/bikepacker that for the past several years gets abused more than the rest of my bikes.  (I am not liking the DOT5.1 fluid, but can live with that if I buy a set.)

I was focusing on "lewis brakes" but after the tariffs were added, why purchase them when one can purchase other more proven expensive brakes

I really wouldn't worry about dot fluid. I'm running a set of Hope Tech M4 brakes currently on my hardtail that I've had since 2011 on a variety of bikes that have only been bled a couple of times and other than pads are entirely original. I run Hope Tech 4 V4's on my Enduro bike that haven't had a bleed since I fitted them and they've been through 6+ sets of front pads. Living in the North of England most of my friends run Hope too and the only real problem I can remember is a mate ruining a set of Mono M4's by leaving them covered in road salt after being on a bike rack.

My new set of Wheeltop mtb brakes arrived today.

Looking at them, the shape of the brake caliper is about 80% the same as the IIIPro calipers.   These calipers appear to be another general variation of the E4 caliper.

Calipers
- Pistons are not ceramic.
- 16 mm pistons
- Pistons have a cross-top X cut into theme where the pads rest. (Versus IIIPros are flat, and the Frog Wakes I recently received have a double cross cut into them.)
- The brake pads are the same as the IIIPros.
- The external shape of the calipers has less machining on the exterior versus the IIIPros.
- I haven't weighed them yet, but they are likely heavier than the IIIPros.  (They should be easier to clean having more flat exterior surfaces.)

The levers, hydraulics and mounting is a new configuration to me that I haven't seen before.   I have to research further.
It appears that the levers are symmetrical so that they can be be ran left to right or right to left.
