Different types of brake rotors we encounter

[Sizzle Chest]

We commonly run into 3 different types of brake rotors.

STEEL/FERROUS

CERAMIC/CARBON CERAMIC

TUNGSTEN CARBIDE



Each type can have a different approache in regards to cleaning, handling, etc.

Steel or ferrous: Pretty much the 'standard' rotor on most auto's. Pretty much impervious to anything we may use on them, however they are prone to rust.

Ceramic/Carbon ceramic: Found on 'high end' sports cars, exotics and some luxury vehicles. Finicky. Please use caution when working on a vehicle with these. The rotors tend to absorb chemicals, are 'delicate' and can crack/shatter if struck, dropped, or mishandled, and are ridiculously expensive to replace. (approximately $3-5K+ EACH). They dust very little and using your favorite car shampoo on them is a good solid, safe cleaning routine.

Tungsten carbide: Found on model year 2020 and newer Porsche Cayenne and Taycan. I typically treat these as I do ceramic/carbon ceramic rotors. (expensive, but not as expensive as the carbon ceramic)









Ceramic/Carbon Ceramic rotors:




















Steel rotors:












Tungsten carbide rotors: (for now, only on model year 2020 and newer Porsche SUV's and Taycan)





Hope this helps everyone out!

Thanks! No idea Tungsten Carbide brake rotors were a thing. I was aware of the ceramics, but this is something new to read up on.

Recently I was at a Porsche dealer and they had a Cayenne Turbo coupe loaded and it had this Tungsten Carbide brake system. The calipers were insanely huge, I guess to stop that big of a vehicle with high performance. These were 21” wheels and look how much of the space it fills.
