Improved friction and fade resistance when compared to OE. Very low brake disc wear. Features patented AF42/66 organic pad friction material and red "Brake-in" coating for accelerated pad bed in period. Greenstuff 6000 series is regarded as a first level brake improvement over stock and can deliver up to 15% improvement in stopping power. However Greenstuff™ 6000 is not a hard and long lasting pad and drivers may find Greenstuff™ lasts fewer miles on light Trucks and SUVs than stock units, which in our opinion are designed primarily to pass the warranty period, but 6000 are a good quality pad replacement with medium dusting and good brake effect. Sold in axle sets.
