CERAMIC BRAKE PADS
Ceramic brake pads are made from material very similar to the type of ceramic used to make pottery and plates. Ceramic brake pad material, however, is denser and considerably more durable. Ceramic brake pads also have fine copper fibers embedded within them, to help increase their friction and heat conductivity.
Ceramic brake pads have consistently increased in popularity for a number reasons:
Noise-Level: Ceramic brake pads are very quiet, creating little-to-no extra sound when the brakes are applied.
Wear & Tear Residue: Compared to organic brake pads, ceramic brake pads tend to produce less dust and other particles as they wear down.
Temperature & Driving Conditions: Compared to organic brake pads, ceramic brake pads can be more reliable in a broader range of temperatures and driving conditions.
SEMI-METALLIC BRAKE PADS
Semi metallic brake pad. Semi metallic brake pads are different from fully metal brake pads in that they use fillers to create the pad compound instead of using 100% metal. Full metal brake pads are typically reserved for truly extreme braking requirements
Semi metallic brake pads are between 30% and 70% metal, including copper, iron, steel, and other composite alloys. These various metals are combined with graphite lubricant and other fillers to complete the brake pad. The metallic brake pad compounds available vary, each type offering their own advantages for everything from daily commutes to track racing.
For many drivers, especially those who value high-performance, the choice between ceramic vs. semi metallic brake pads is easy. Performance-driven drivers tend to prefer the metallic brake pads because they offer improved braking performance in a much more comprehensive range of temperatures and conditions. Because metal is such a good conductor of heat, metallic brake pads tend to withstand more heat while simultaneously helping braking systems cool back down more quickly. They also don’t compress as much as organic brakes, meaning less pressure needs to be applied to the brake pedal to affect stopping ability.
However, there are some disadvantages when it comes to metallic vs. ceramic and organic brake pads. Metallic brake pads tend to be noisier than their ceramic or organic counterparts, leading to a louder ride. Metallic pads also put more stress on the brake system, adding more strain and wear on the brake rotors. As far as price goes, metallic brake pads tend to fall somewhere between organic and ceramic pads. They tend to produce more brake dust than the other two varieties as well.
