Ask a Automotive Brake Engineer
June 8, 2015 at 6:47 pm
Just a post to answer any Braking systems questions or general automotive industry questions.
I have a lot of experience in Sensors and their manufacture as well.

Why did the engineers that created the tire pressure monitoring system hardware make it battery operated?
It seems that plenty of energy could have been siphoned from the turning wheel and the system wouldn't reliably fail in about 5 years.
I have my theory, it involves them being evil puppets of MBAs.
So how, exactly, does God know that She's NOT a brain in a vat?

Price of manufacture. I've heard of newer TPM's that power off the Rotor or knuckle magnetism, but I've not seen one yet.

Only if you work here at my plant. We soulless, lifeless engineers are pathetically boring.

I worked for a wholesale parts distributer. Can you tell me what brand of pads you like and if cost equals performance?

Are the ceramic pads really the pad to end all pads?

"Cereamic" pads are the industry joke. There is no such thing in the normal sense of fired ceramics. When you make the pads harder than the rotor, it is the rotor that wears away and becomes disposable, and that is dangerous because a rotor does not have any wear indicators as a pad does.
All modern friction materials are cooked/ glued onto the backing plate, never fired inside a kiln.
The claimed "benefits" usually given for "ceramic" (air quotes!) brake pads are low dust formation and extended wear, but both of these are HUGELY related to wheel & rotor wabble known as LRO (Lateral Run Out) If you match your axle and rotor surface to less than 5 microns variation while you rotate the rotor you will not experience brake dust and your brake pad lining will most often out last your vehicle.
Brake shops won't do this because they loose repeat customers and OEM manufacturers don't do it because it takes to much manufacturing time.
