Product Description The sintered compound of the pads is harder and has no loss of braking power in rain and snow. Semi-metallic allows for a more even distribution of braking force at each stop. The special compound of the pads is carefully matched to the material of the disc. The excellent deceleration values are not, as usual, achieved at the expense of excessive pad wear.
