Sticky caliper ?

[newTahoeguy]

Before I get to taking this rear right caliper apart just wondering if anyone has thoughts based off pictures it looks like the rotor has wear along outer edge, would that most likely just be from the slide pin boots blown out or the whole caliper going, wheel spins freely when I had jacked up, but my vehicle is definitely pulling to the right when driving and recently started pulling left then right when hard braking at highway speed

Time to tear it apart and see what it looks like. Hard to say just from looking at one rotor. Time for new rotors and pads regardless so I’d have those parts ready if it was me. New calipers might be in order also but you wont know until you get into it.

Those slide pins can sure rust up and cause several problems. Hard to get them out too, parts loosener, heat, lots of patience.

Nice pics to tell the whole story.

It’s just an internet diagnosis, but going to the cheapest, easiest first methodology, consider an internally gummy / sticking brake hose allowing the caliper to drag.

It’s a good excuse to upgrade to braided stainless lines and still get a win if that doesn’t correct it.

As @Rocket Man recommended, tear the caliper apart and assess. Cleaning and re-lubing the pins may resolve your issue. I believe that PowerStop pads include new rubber boots for the caliper pins.

Pull the wheel and before doing anything try to slide the caliper side to side to see if it floats. Then go deeper.
