Hi. How does one tell if a front brake caliper (or any caliper really ) is dragging? ie is there a test ? I think I may have a dragging brake caliper on my 2010 Supercharged 5.0 Sport.

All works fine, but left front brake constantly slightly squeals while moving, whether or not brake is depressed. And the left front pad is wearing more quickly than the right front, noticeably so.

I had a sticking calliper on the Shogun last year, I noticed there was more brake dust on one of the wheels than the others, also after a drive if I felt the wheel it was noticeable warmer than the rest and finally when the car was jacked up if I rotated the wheel by hand you could tell it had more resistance than the when checked against the opposite side. I tried cleaning all the slides up but when I tried to push one of the calliper pistons back in I found it had become stuck. In the end I fitted new calipers as they were cheaper than a new seal and piston kit.

As said feel if one of the wheels feels warm if it does then that is the caliper with the issue

Replaced the front calipers and all is well. Front left was indeed dragging. Not sure why, internal fault apparently.
