Did I install my rear brake pads correctly?

Hey quick question...

I just changed my rear brake pads today, and I was able to get the piston pushed in JUST ENOUGH so that the new pads would go over the rotor. However, I never got the piston all the way in flush. I assumed everything was okay since I was able to get everything assembled back together.

The quad seems like it rolls just fine, and the rear brakes work as they are supposed to (after bleeding of course).

My only concern is that since I never got that piston pushed all the way in flush, I feel that the brakes may be rubbing against the rotor even when not engaged. Shining a flashlight in there, the brakes look like they are making contact with the rotor even when the brake pedal is not engaged.

I'm wondering, should I see "space" between the pads and the rotor? I just wanna make sure I did everything correctly.

Thanks!

PS - the Ebrake has always been disengaged since I bought the quad if that makes any difference with how the braking system functions.

If it rolls free you should be good.

Cool thanks! I wasn't sure exactly how the brake system works and what causes the pads to retract once the pedal is disengaged.

Calipers in general use a square cut o-ring to seal the piston in the housing. As the pressure pushes the piston outward the o-ring rocks outward at an angle. Then when the pressure is released the o ring rocks backward pulling the piston in slightly.
