Why do rear disc brakes make a noise?
The master cylinder sends pressurized fluid through the brake lines. If you have rear drum brakes, the fluid causes the actuator to push the brake shoes outward, where they press against the inside of the drum. In the case of rear disc brakes, the fluid activates the caliper, which then squeezes the caliper between two brake pads.

Why does MY BMW make so much noise when I brake?
3) Rear rotors which have a handbrake shoe built into the rotor are the worst of all cases. These are on the rear wheels of BMW, Mercedes and Volvo cars and our research has found that the hollow and sometimes thin sections of the drum bore can cause a resonance effect and greatly exaggerate rear brake noise which in some cases NEVER goes away.

Why are my brake pads making a squeaking noise?
If your brake pads are used for quite a long time, the backing plates will gradually lose its material. This causes metal touching other metal, resulting in squeaking noises. Besides, the rotor can also rub the caliper and scrape its meal surface. Thus, if you do not replace the pads immediately, your brakes will be severely broken.
What’s the difference between front and rear differential noise?
Only difference between a wheel bearing noise and a rear differential noise would be the fact that the wheel bearing noise will change with wheel speed but usually will not change with load variations (accelerations/decelerations) while the noise from a rear differential will change with wheel speed and load.
