I've got my set of brake pads too, from Textar, they came with the fixing kit included like most of them come. The sticking brake can't be from the the fixing kit and I can bet on it, most likely its the ABS valve on that side or the software as the issue its very common. Fixing kits are changed every time we change the brake pads. I had changed the caliper, the hose, the disc and the brake pads with the fixing kits and still have the same problem. That's why I'm betting on the software which controls the ABS or the ABS module itself.
And if you want to get rid of the squeaky noise, you have to apply some copper or ceramic grease on the back of the brake pads, where they come in contact with the piston. This should solve it, if not, the brake pads are too hard, this depends on the make, usually the low quality ones are hard and they do squeak no matter what.
