Ceramic pads

Pros:

+ Quieter than semi-metallic pads - emit noises that are above the range of human hearing
+ Produce finer, lighter-colored brake dust which does not stick to wheels
+ Longer lifespan than organic or semi-metallic pads
+ Do not wear as much on the rotors as the other pads do
+ Stable under a wide range of temperatures for consistent performance

Cons:

- Typically the most expensive type of brands
- Do not produce as much cold bite as semi-metallic pads - may not be ideal in extremely cold climates
- Do not absorb heat as well as semi-metallic pads which can increase brake system temperatures
- Good all-around braking characteristics but were never designed as heavy duty/racing brake pads
