The wife has a 2014 s80 with electronic parking brake. I recently did the back brakes and followed the manual instructions got everything back together and there is a clicking sound coming from them. Tore back apart checked everything and still it's there. Sounds like when as a kid you put something in your bike spokes. Had a mechanic buddy look it over and he said everything was right. Anybody have any thoughts on what it could be? All help is appreciated as it's driving me nuts.

Clicking when? If you have a parking brake failure message, its likely you broke the worm gear in the caliper. You'll need replacement calipers. Try engaging the parking brake and releasing a few times. You should hear the motors activate and that whine noise as they clamp down and park. If its just clicking, yeah, sometime is broken.

The parking brake motors whine and engage fine. When driving is when the clicking noise presents itself. Best way I can describe it is like when a kid puts a card or something in his bike spokes clicking. Speed up and clicking does as well. Slow down and it slows as well. Both sides have the noise.
