Brake Smell?
Had a question for all the brake guys here.
Except for a set of dual piston calipers and and adjustable proportioning valve, I've pretty much maxed out my braking system in terms of stock options. The rear brakes are thermoquiet shoes with aluminum drums and I have SSBC slotted rotors and the matching set of SSBC pads on the front.
Now, it has been around 8 or 9 months since I did the last brake job and they've been performing and functioning great. However while datalogging my car a few weeks ago I noticed that whenever I would make a high speed stop I would get a smell from my brakes that bears a striking resemblence to an electrical fire. These stops were made from about 110MPH with moderate braking force. Not "clamming" them on or with enough force to cause the wheels to lock but from triple digit speeds I had roughly 150 - 200 feet to slow the car down enough to make a 110 degree turn so that should give you an idea.
The brakes did not fade and made subsequent stops just fine but has me a bit curious if this is out of the ordinary.

Re: Brake Smell?
I'll call BS on your numbers. A ZR1 Vette with 15.5" carbon ceramic brakes stops 100-0 in ~300ft. There is no way you are stopping a heavier car with 10.5" stock brakes enough to make a 110 degree turn from 110mph using only "moderate" braking force.
What you are smelling is probably the pads heating up. They smell kinda similar to an electrical fire when heated enough. Honestly the OEM 10.5" setup is junk. I wouldn't do to many stops from triple digits on these brakes.

Re: Brake Smell?
I also didn't say that I was coming to a complete stop before I made the turn. 60ish MPH is what I had to slow the car down to.
In hindsight, the word moderate was inappropriately used and TBH although I can properly judge distance I'm pretty bad at giving a numerical estimate on it, however there was no need for the hostility in your response.
