Not if you're careful...if you get any air bubbles in the brake lines, then you DO need to bleed 'em.
Good luck!

As long as you do not break the cylinder seal(s) you should not have to bleed the brakes.
When you open the bleeeder valve on the back of the drum ( to expand the calipers) do not allow it to suck in air. There are one-way valves you can buy that will insure this if you are not certain, or simply put a hose on it and insert the hose into a can of brake fluid just as if you WERE bleeding the brakes.
If air gets into the line, however, you must bleed the brakes
good luck

I just changed brake pads on rear disk brakes on a ford contour the other day and no, you don't need to bleed the brakes. the only thing i ran into was to push the pistons back in i needed needle nose plyers, and had to twist and turn to get them back in. I've did a lot of brakes and this was the first time I saw that. You'll know if you look at the end of the piston and see a funny looking design on it and a liitle hole you can stick the needle nose into.

No. You only need to bleed the brakes if you open up the hydraulics at any point in the brake system. Changing pads does not normally require doing that.

no not as long as you dont unscrew the bleeder screws.. if u do afluid will leak out and an air pocket will ensue // if your brake pedal feels spongy when you get done i would bleed all the brakes anyway just to make sure of no air// the correct way to do that job is with special tool to compress the caliper plunger back down flat or a c clamp will also work good luck

This is my usual procedure in changing break pads: Pull of caliber part . Remove the lid to the break fluid reservoir.
Take a large pair of pliers or use a screw driver to push the old pads in as far as they will go.
Place new pads in
Replace caliber.
Replace Reservoir lid
Pump breaks and test whether they are operational. Only if your pedal doesn't seem to have any resistance bleed the brakes.

the only time the brakes need to be bled is if the brake fluid has gotten contaminated from pouring somthing other than brake fluid in it or if u have a broken brake line and are opening the system or changing the master cylinder

when you press the calipers in to allow the new pads to fit over
the rotors, you always have some fluid loss. if you refill the
brake fluid resevoir before mashing the brake pedal, you
should be alright. if your brake pedal is spongy or you get more
pedal after pumping, this indicates air in the lines & you should bleed them. always check brake fluid levels &refill before trying
the brakes after a brake job

If your careful and don't mess with the bleeder valve you should be okay, I've always figured while there why not go ahead and check the system. Preventative maintenance.

not quite.
when You push the caliper piston the fluid will return to the master cylinder (and may be overflow it)
