Shimano BP-D02S-MX / BP-D03S-RX Disc Brake Pads

Shimano D-Type 4-Piston Disc Brake Pads (D02S Metal / D03S Resin)

Unleash the full stopping power of your 4-piston brakes with genuine Shimano D-Type replacement disc brake pads. Specifically designed to handle the high thermal loads and intense braking forces of modern aggressive trail riding, enduro, downhill, and heavy-duty e-MTBs, these pads ensure consistent lever feel and uncompromising control.

Available in both D02S-MX (Sintered Metal) and D03S-RX (Resin/Organic) compounds, this listing lets you select the precise friction material to match your riding style, weather conditions, and terrain preferences. Both options feature a robust steel backing plate and are supplied in individual retail packaging complete with spring and split pins.

Compound Options

1. D02S-MX — Sintered Metal (Maximum Power & Wet Weather Endurance)

• Compound Material: Sintered Metal

• Characteristics: Delivers maximum stopping power, exceptional high-temperature fade resistance, and long-lasting durability in harsh, muddy, or gritty environments. Ideal for steep alpine descents and heavy e-MTBs.

2. D03S-RX — Resin / Organic (Maximum Modulation & Silent Operation)

• Compound Material: Resin (Organic)

• Characteristics: Offers ~40% better wear resistance than previous generation resin pads (such as D01S) while maintaining near-silent operation and instantaneous low-temperature bite. Excellent lever modulation with lower rotor wear.

Key Features

• Genuine Shimano D-Type Fitment: Engineered specifically for Shimano's high-performance 4-piston mountain bike and trekking brake calipers.

• Durable Steel Backplate: Provides strong structural support and consistent piston pressure across the wide 4-piston surface.
