Was getting some dragging noise from the front left. I replaced the rotors and pads but am still having the light dragging sound. I did notice when changing the pads/rotors that one of the caliper guide pins were pretty tight. I cleaned up the pin and relubed it, but still having the same issue.

I am guessing the calipers are slightly sticking? causing the pads to rest on the rotor and hearing the dragging sound?

So far it does not seem to affect brake performance and I can still turn the wheel fairly easily. just the annoying "cheuu cheuu" sound. The sound is gone when pushing on the brake pedal. its only apparent when the brake is not applied.

Should I go ahead and replace the caliper or could something else be causing this?

Caliper could be hanging, also maybe a bad or swollen rubber brake line...Had that happen on a General Motors Car.

how to tell if the caliper is the issue or the brake line?

My first guess would be due to the age of the vehicle and where you live...it's the caliper.

If you have a temp infared guage, you could take a road trip, and stop and measure temp on opposite wheel and problem wheel. If the brake caliper isn't releasing than the temp should be a lot higher. on bad side.

Did you bleed the brakes? Trapped air expands and can build pressure. It also does not act to retract the piston when the brakes are let off.

Also with the pads out, does the caliper slide back and forth freely?

No I didn't bleed the brakes. the last time the brakes were changed (only 1.5 years ago, by mechanic, the brakes were bled that time). surprised that the pads only lasted 1.5 years as they've previously lasted 3-4 years. and supposedly he used oem (akebono) pads.

I normally change the brakes myself and usually bleed the brakes once each brake change which is 3-4 years. So I didn't bother bleeding brakes this time since it was only done 1.5 years ago by mechanic.

not sure if my temp gun is not reading properly but I am reading fairly low temps of between 26-35C on both rotors depending on the area of the rotor i point it to. Not sure if i am imagining it but im pretty sure the side thats slightly dragging is warmer than the other side (not super hot since i can still touch it with my hands after a 15 minute drive)

Also after bedding in the brakes, the scraping sound has definitely gone a lot quieter (this wasn't because of new pads/rotors since the old ones were making the sound before i changed it) I am thinking maybe by hard braking when i was bedding in the brakes, it may have broke free the slightly seized caliper?
