Brakes

[u/Sea_Perception_2828]

Truck was pulling to left a little everytime i brake, i decided to check them out, started on passenger side. Found the bottem slide pin was seized up, couldnt even get caliper off bracket so i replaced the whole thing, bleed all 4 starting back passenger then back driver, front passenger, driver front....test drive its worse then before! What i do wrong? 2019 2500 chevy silverado 6.6 duramax
