Went for a quick drive around the block. When I got back my Tahoe was feeling heavy. I felt my brakes locking up parked I smelled brakes walked around looked at all my rotors and saw this. Would this be an indication of a bad caliper? I cleaned the area right after the brake pad, you can see my finger outline. None of my other calipers looked like this. Here’s a picture any help would be appreciated.

 

Was this quick drive done because you just replaced something, like a master cylinder?

 

Just had to move it, to a different spot cause of rain. I actually did have the master cylinder replaced a while back ever since then I’ve been having this locking up problem.

 

I think you have a bad adjustment on the brake pushrod, so always some pressure on the brake master cylinder. Makes sense, and why I asked if the master cylinder had recently been installed.
