Some higher end vehicles use pricey carbon ceramic discs or even special tungsten carbide.
Do carbon ceramic brakes squeal.
Don t write this off as a different kind of brake squeal.
The carbon ceramic brakes fitted as standard on many high performance vehicles are constructed in one of two ways either a core of ceramic material reinforced with chopped carbon fibre with an additional ceramic layer on the friction surface or simply the core of ceramic material with chopped carbon fibre and no outer friction layer.
If your brakes grind or grab or your car pulls to one side when braking that s a different story.
The squealing is normally the result of not using a brake lining shim or not putting enough anti squeal.
Carbon ceramic brakes don t provide the same feedback as conventional brakes.
The wear indicator makes more of a ripping.
That high pitched sound burrows into your brain stem making you seriously consider crashing into the stopped car ahead rather than step on the brakes and subject.
This is because carbon ceramic brakes were designed to function at high speeds and temperatures.
Brakes squeak squeal or screech when vibrating brake pads produce a sound in a specific frequency.
At lower speeds and temperatures in particular they can feel soft even squishy leading you to over apply them and experience a jerky ride.
That sound however doesn t mean your brakes are failing.
