Brakes Pulling

My first post here.
I have an 02 Tahoe, 4WD
The brakes are pulling hard to the left, so I replaced all 4 calipers and cleaned up the pads and brackets, new pins and slides installed. Bled all 4 wheels , they have good fluid at bleeders.
It still pulls like before.

Does anyone have any ideas of what I should try next?
The only thing I can think is I got a bad caliper from Oreilly
Thanks RB

might be a bad brake hose to the left caliper. being you got the same issue after replacing the calipers.

how did the pads look? even wear? same on the rotor it even across it?

Going to dump at you a bit here. Normally I'd put into bullets but too much of a pain on mobile so bear with me

Replaced calipers but kept pads and rotors? Did ya resurface the rotors and flat sand the pads? Check for any glazing? Pads installed correctly? Any rust/surface pitting on rotors (will change coefficient of friction)? Dumb question here but I'd hate to skip over it anyway: we're the slide pins lubed with appropriate grease? And do the pads move freely in their bracket?


In addition to what's been posted about brake lines: what does your alignment look like? Tire pressure? Does it pull to the left on all roads? Steering tight (incl upper and lower ball joints)? Wheel bearings good? What happens if you perform a side to side rotate with your tires?
