There might be some side-to-side free play between the brake pads and the calipers. On the GD-series Cities and Jazzes, that's considered normal. Not sure if it's the same on your EK4 SiR though.
what kind of brake pads are you using? in my experience, some replacement brake pads aren't perfectly fit. some mechanics install a small piece of iron sheet to fill the gap/clearance.
