Just a quick update on both items I mentioned in my last post above:
1) TPMS light
The TPMS light has turned off now. I still have no idea why it came on, or what precipitated it. I've verified my tire pressures again are correct and even across all 4 tires. ¯\_(ツ)_/¯
2) Noisy brakes with Ferodo DS2500 pads
Noise has reduced somewhat, but is still present when coming to a stop at stoplights. Effectively noise doesn't occur until I'm inching forward at this point. When I'm hard on the brakes, it is quiet. There was an additional noise when traveling at speed which sounded like high frequency bells that I determined was vibrations of the brake pads in the calipers. I applied some Permatex Silicon Ceramic Extreme Brake Parts Lube to the backing plate of the pads and this eliminated the vibration noise at speed, but did not seem to affect the squealing during stops at all. The harder I stop, the quieter they are, but this unfortunately isn't very friendly to trying to park in my garage so my neighbors have been giving me the death glare. I sent an email to CSG to ask about their thoughts on the Carbotech 1521 since they'd recommended it to solve this issue in a past thread I found searching the forums.
