I've never heard a spring pop. With that in mind, you would be best to take your car to a dealer, replicate the sound for them, and have them fix it.
There is a spring on the brake pedal that has a rubber noise reducer in it. If that rubber piece fell out, the spring might make noise. It will have no effect on the car's braking system.
If you are hearing a spring sound outside the passenger compartement, you may have a sticky parking brake. Again, it's a dealer repair item.

Emotional Arguments - they're not just for chicks anymore.
Most performance mods need a watch and timed course to demonstrate actual improvement. Few deliver the advertised claims. Many are actually worse than stock. The best performance mods are made to the driver.
