Austin:

I currently have the original aluminum Brembo calipers on my 500. The stopping power on the street appears to be adequate. I did experience the 'problem' that these Brembos are famous for ... noise and vibration. I was running stock (OE) pads (which I replaced due to an excessive dust and vibration problem) and where approximately 75% worn. An intermittent, low frequency vibration would be felt through the steering wheel. This only occurred at approximately 40 mph - no braking, just in motion. Tap the brakes ... very little force, and the vibration went away. There was no apparent loss of performance during this time.

I changed to EBC RED pads and the vibration went away. I believe a resonance condition exists when the 'system' variables are just right ... as the pads wear, the 'system' mass changes and goes into a resonance condition. If it happens again, I'll just change my pads … so much for the pad sensors! Now, if I upgrade to 18” wheels, Daddy’s getting new brakes!
