Brand new brake pads in but back wheel still doesn’t stop at all when I’m pushing the bike from stationary even?

Glazed rotor or contaminated surfaces clean with degreaser and then soap then water 💧 should brake alittle better but need to bed them in to have good braking.

Those brakes are hydraulic. Your seals need to be replaced and then fill with fresh oil. Slap on a boot to keep water out and youre golden. But honestly, those xtech hydraulic brakes are garbage without overhauling them.

Brake fluid need to be changed lol seriously
Rogue_Wraith@reddit
Are you suggesting changing brake fluid on a cable brake setup?
Antidotebeatz@reddit (OP)
These are semi hydraulic brakes that are still cable attenuated and do need to be bled. Yes it’s stupid asf. But I still don’t think that’s a fix for why they aren’t stopping the wheel at all

That...is really bizarre, and I would not have expected that.

Not really bizarre at all tbh. Cable actuated hydraulic brakes have always been shit.
Inciteful_Analysis@reddit
That or the seals are probably blown and changing fluid won't help.

Would it have hurt to lead with these are hybrid mechanical/hydraullic brakes?
And note whether the cable is actuating the hydraullic plunger?

Looks mechanical to me 🕵️♂️
Inciteful_Analysis@reddit
It's both. That's what the word hybrid means. OP already confirmed.

Looking at the caliper, you contaminated your pads
Antidotebeatz@reddit (OP)
The pads are brand new? I think I found the issue though. Broken barrel adjuster

Mechanical brake? You align the brake by clamping it tight while setting the screws holding the caliper. Then you set the barrel at the brake lever all the out. Then use the twist adjustment at the caliper until it's tight to the rotor and doesn't spin freely. Then go back to brake lever and turn the barrel until it is tight to the lever. The brake should be aligned and spin Freely. The lever should be able to stop the wheel and have ample space before hitting the handle. If at any time the lever gets close to touching the handle the brake needs adjustment which you can typically quickly do while out with the barrel adjuster.
Hydraulic I typically open the reservoir and push the pistons back in using the old pads before putting in new pads. If it needs bleeding or adjustment I'd take it into a shop.

You probably have cable slack if the brake lever goes all the way to the handlebars. Look up how to adjust mechanical disc brakes on YouTube.

have you tried adjusting cable tension? try turning the barrel on the brake lever and also on the brake caliper, see if it'll increase the pad's bite. if that doesn't, loosen the screen holding the cable on caliper and pull it to make more tension on it and retighten the screw.
