And just because it is Monday : Many disc brake pads are available in different compounds Medium Compound Also known as Compound S (Medium) Containing metal and graphite for long wear. Great for muddy conditions, and a good choice in all conditions. A medium compound with consistent wet performance and good grip. Advantages: Cheap, Above average all around performance Disadvantages: Grippier and longer lasting pads are available Suitable For: Everything Conclusion: Best Value Superlight WorldCup Competition Alu Backed Pads use the medium compound. Professional Grade Black Ceramic Compound Also known as Compound C (Ceramic Pro) These soft organic ceramic fiber disc brake pads are carbonized. The ceramic compound insulates the brake system from friction heat up to 400oC. The result is a very powerful, quiet pad with extremely low heat generation which all but eliminates the chances of brake fade. Details Upgrade on original fitted pads DIN 79100 Standard Approved Organic Compound contains no metal material Reduces damage to rotor Carbonized compound reduces brake fading Ceramic Fiber insulates brake system from friction heat Non-Asbestos Advantages: Excellent grip, Low noise, Low heat, Consistent in all conditions Disadvantages: Short life span unless rider is light on brakes Suitable For: DH, Dry XC, Ti Rotors Conclusion: Best Performance, Short Life Metallic Sintered Also known as Compound T (Sintered) Superior power in all conditions Long wear pads, great for DH or XC Consistent braking power in the wet Almost unaffected by rain and snow Advantages: Better performing and longer lasting than most pads Disadvantages: More expensive than medium pads Suitable For: XC, DH (low brake use), All weather conditions, Mud Conclusion: Best All Rounders Red Ceramic Compound - Hard Also known as Compound D (Ceramic Hard) Harder than ordinary pads. This is the highest density, hardest, ceramic compound for ultimate performance and the longer lifetime. These organic disc brake pads contain a high amount of ceramic fiber, which insulate the brake system from friction heat up to 400oC. Advantages: Better performing and longer lasting than medium pads Details Upgrade on original fitted pads DIN 79100 Standard Approved Organic Compound contains no metal material Reduces damage to rotor Carbonized compound reduces brake fading Ceramic Fiber insulates brake system from friction heat Non-Asbestos Advantages: Longer lasting than Black Ceramic pads Disadvantages: More expensive than Black Ceramic pads and not as grippy Suitable For: XC, DH (low brake use) Conclusion: Ceramic Advantages with Longer Life Other Factors Low Noise: The black ceramic compound C is thought to be virtually silent DH: Black Ceramic pads are great for Downhill as the ceramic compound insulates the calliper pistons from heat build up so reducing the likelihood of brake fade. Rotors: All of these compounds can be used with any rotor. Ceramic pads cause less damage to rotors than metallic compound pads. Titanium Rotors: We recommend black ceramic compound for titanium coated rotors, as it contains no metal, so will reduce damage to the rotor. The coating on titanium plated rotors is extremely thin (often just a few microns), so will ultimately wear off no matter what pad you use, but ceramic pads will prolong their life over pads containing metal.
