Details
The leader in racing brake pad material, Brembo Z04 Racing Brake Pads have won more Superbike and Supersport races around the world than any other brake material. The ultimate in terms of high brake co-efficient has been the choice for many years of all leading World Superbike and AMA race teams. The Mu value of this pad is the highest of any sintered race material in the market and this provides excellent "High Initial Bite" which is crucial for late braking techniques used by modern riders. The stability of the friction level while on the brakes in “cornering” allows the rider to modulate the brakes very accurately without upsetting the geometry of the bike. Although considered expensive in initial purchase, teams and riders realize that the low wear rate of the pad converts to long life and outlasts other race brake compounds. Combined with its unrivalled performance this longer life means unmatchable comparisons in any conditions. Z04 compound is available for all Brembo Race calipers and for most Japanese and European sport bike applications.
