brakes do not release
If you replace any brake component that breaks the brake fluid seal or you let it get very low of brake fluid, yes, you must bleed the brakes.
There should be no need to bleed the brakes after replacing the rear (or front) brake pads. Make sure you place a rag around the top of the fluid reservoir to catch any excess as you press the pistons back into the caliper body though. If the brake pedal has gone spongy after pad replacement this suggests that the piston seals have failed or the caliper cylinder facess have corroded. On mine the bleed nipples are on the caliper body.
