pulling hard right when braking on 1998 Dodge Ram 2500

when i brake the front right wheel pulls very hard ton the right please help thanks

Asked by for the 1998 Dodge Ram 2500
It could be that the left caliper is frozen and only the right caliper is grabbing and causing it to pull to the right, I have the same truck and every time I change the brake pads I have to pull the slide pins in the caliper and relube them because they are frozen in place

i have the exact same problem with my 98 ram 2500 diesel, and have spent over $800 at two different shops changing out everyyhing they can think of, including both calipers, with no change. both machanics are stumped.
a pontiac i had kept the brakes on side pulling the car. auto parts guy said replace the rubber brake line as sometimes they collapse inside. fixed my car.
