Where did you get the caliper and what brand is it?
Also if it was the master cylinder I would imagine all of the brakes would not return after they were depressed....why would a master cylinder only affect one wheel?

Violent shaking when braking

That happens also.......my friend wrecked his motorcycle when the front wheel locked up from a bad MC. I do agree it should effect more than one wheel.

i got it from autozone. it is duralast. and yeah it would make sense for it to effect all the brakes but it could also be one of those one-off things where it only effects one. and it’s effecting the closest brake to the master cylinder. It would be really really REALLY odd to have the same problem with a new caliper on the same wheel as the prior caliper. leads me to think it’s probably not the caliper but i could totally be wrong. i’m also replacing my CV axle under warranty because it had a little bit of wobble when spinning the wheel. don’t think that’s the problem but better safe than sorry.

Did you ever try doing what DirtDrift suggested? I may have missed it if you did. This will help you to figure out if its coming from the front or back and narrow down your troubleshooting.

There should not be any wobble on the CV axle at all. Are you sure the axle is pushed into the differential and the nut torqued properly?

Yes i did. sorry i forgot to reply. there is no major shake when just the e-brake is pulled. however there has started to be a constant rotational shake when accelerating slowly or decelerating. pushing the petal makes it worse, pulling the brake keeps it the same

That seems to narrow it down to the front and I'd be taking a serious look at that wobbling CV axle. That is not normal and needs to be fixed regardless. Axle problems could definitely cause steering/braking issues.

yes. it was still very hard to get the cv out so i’m assuming it was in all the way

I'm suspecting it's the caliper, here's how to determine 100% if that's the case, depress your brakes so that the wheel becomes hard to turn, i.e. caliper pistons are sticking, caliper pins binding or there's pressure not being released at that wheel, now open the bleeder valve, by doing this you have just release any pressure that may still be going to that caliper, if the wheel turn easily now then it's an issue with the hoses, steel brake lines or master cylinder.
If the wheel is still hard to turn it's for sure the new/rebuilt caliper or pins, etc., replace the caliper/pins and that should solve the dragging issue, which could or could not be the cause of your vibrations.

Super good idea! That will confirm it is the caliper.
As others have said getting a bad rebuilt caliper right out of the box can happen. All it takes is for one of those pistons in the caliper to be banged up and the brakes will drag.

Get all new (4) calipers for the front wheels. Take to a brake shop for installation and diagnosis.

Maybe the brake shop will be able to figure out where to put the extra 2 calipers.
