The Shimano D03S brake pads are 40 % more durable than the previous D01S model, but continue to impress with low noise levels, as is usual for resin pads. They are also clearly above average in terms of modulation. The D03S is compatible with Shimano 4-piston brakes - BR M8120, BR M7120, BR 8020, BR M820, BR M810, BR M640, MT501, MT520, MT420.
