Well as per my knowledge, ceramic brakes are never for heavy duty trucks and SUVs as metal lining is required to hold the heavy load.
And might be what you tested are purely racing purpose ceramic pads which need to get hot to do its job effectively. Racing pads have poor stopping power when cold and also u will feel hard.
Now a days - consumer grade ceramic pads are avaialble having great stoping power and are much smoother. But actual differnence will feel in abusing it.</SECTION></SECTION>
