When replacing pads and pushing the piston back in, do I need to open the bleeder valve? I've never done this in the past, but I've been reading some info that suggests this. I usually just open the brake fluid reservoir while pushing the piston(s) in. Thanks!

There's no need to do this. Do keep an eye for overflow at the reservoir as you compress the piston if fluid is already close to the top, and pump the brakes after each wheel to bring the fluid down to normal height before compressing the next piston.

It's good practice because it ejects the most degenerated fluid from the system, plus it stops the bad fluid from returning to the ABS actuator.

That said, I don't do it unless the caliper is sticking or possibly overheated.
