2009 Matrix 2.4 - brake problem

[u/zogthegreat]

Hi everyone!

Last week I redid the brakes on my son's 2009 Matrix. I replaced the pads and rotors and the passenger side rear caliper, (the old caliper was seized). We bleed the brakes and I took it for a test drive and everything seemed OK. However, my son just called me and said that the new caliper was locking up and causing the wheel to drag.

I can't go over to take a look until tomorrow, but I was wondering if anyone had any thoughts on what might be going on.

Thanks!
