I'm changing my pads and rotors soon, but I was wondering when I remove my old pads and insert the new ones do I need to open the bleeder valve to push the piston back in or can I just push the piston back in with out messing with bleeding? And will this require me to bleed the brakes if I change the pads ? Thanks

No, don't open the bleeder valve. Pop the hood and loosen the brake reservoir cap to relieve the resistance.

Fluid should ideally be changed once a year

If it's about that time best bet is doing it all at once - good brakes starts with fresh clean fluid

Chuck Dub is correct. Depending on how worn they were/are, a lot of fluid may come out but not enough to overflow. Just use a paper towel to get rid of some of the fluid if its way over the max fill line. Shouldn't be too bad.

Also on pushing the pistons back, it may be stuck. One of mine I could use my hand to push it back but the other I needed a piece of wood with a large C Clamp to get it moving.

One more tip: Giant breaker bar, 1/2 in drive. Turn wheel to the side to get to the caliper bracket bolts. Don't know if you needed the extra info but whatever.

Thanks for all of the info

Yeah, don't open the bleeder valve. Doing will may allow air to enter your brake lines, then you would have to bleed them. Not necessary for a simple pad and rotor change.
