I have a 2010 ram 4x4 I noticed the front rims was getting hot, so I jacked up the front end, both front tires are hard to spin by hand. So I suspect frozen calibers or a bad rubber brake line off the caliper. I was told to break the bleeder open and see what happens, both bleeders broke off. So I replaced both calipers, both rubber brake lines, new pads and rotors, yes the slide pins was also greased. Did a brake bleed, test drive, both front wheels again are hard to turn by hand. Both wheel hubs was just replaced 2 months ago, and when the brakes was off, the hub spun with ease. So I’m asking would a bad master cylinder cause just front brakes to drag. If not I’m also looking at the abs pump being the culprit. Also both back wheels spin by hand, no drag.
