89 c1500 brake problem

My truck when braking was pulling to the left bad in the front I checked the front calipers and the one on the right was froze up I replaced both calipers, brake pads, and had the rotors turned and it still pulls to the left when braking, not as bad but still pulling. the master cylinder seems to be alright replaced about 1.5 yrs ago. what else could be causing this?

flexible brake lines OK?

flexible brake lines OK?
You know I don't know never thought of those. I will replace and see.

Thanks

I've heard of them collasping & ballooning when they get old &
deteriorate inside & causing hard to diagnose probs. I think
all that proportioning stuff is just front vs back but maybe somebody
would know if any of that could cause that symptom.
People will also ask if you lubed the sliders properly. Good Luck

Thanks for the info on the flexable brake lines I replaced them this evening and no more pulling when braking. Thanks again
