4 Pairs Semi-Metallic Disc Brake Pads for HD-M520 M521 M510 M500 M501 M352 M350 M351 M330 M301 Calipers | Bike Replacement Pads

Upgrade your bike's stopping power with a set of high-performance disc brake pads designed for a wide range of popular hydraulic calipers. This 4-pair pack offers reliable, low-noise braking for mountain bikes, road bikes, cruisers, and more, making it a smart choice for regular maintenance or a performance boost.

These pads feature a semi-metallic compound bonded to a steel backing plate. This material choice balances strong braking force with quieter operation compared to fully metallic pads. The formula includes Kevlar fiber to extend the service life, giving you more rides between replacements.

Heat dissipation is a key factor in brake performance. These pads are designed to manage heat effectively, helping to maintain consistent braking power even on longer descents. The new formula also incorporates red copper granules to further enhance stopping capability and durability.

Each pad is tested to meet EU standards (EN14766:2005), giving you confidence in their performance and safety. Whether you are upgrading worn-out pads or building a new bike, this set provides a dependable and cost-effective solution for your hydraulic disc brakes.

Key Features and Benefits

• Kevlar fiber in the material that increases the lifespan of the pads, meaning fewer replacements over time.

• Improved heat dissipation that helps maintain consistent braking performance during long or steep descents.

• Red copper granules in the formula that enhance braking power and overall durability.

• Tested to EU standard EN14766:2005, ensuring reliable performance and safety compliance.

Who Is This For

Usage Scenario

Mark had been putting off replacing the worn pads on his mountain bike. The last ride down a rocky trail left him with a squealing noise and fading power just when he needed it most. After swapping in this 4-pair set, the difference was immediate. The pads bit firmly from the first pull of the lever, and the noise was gone. Now he feels confident tackling those long descents again, knowing the brakes will respond when he needs them.

Micro Comparison

While some budget pads use a basic resin compound that wears quickly and fades under heat, these semi-metallic pads offer a longer service life and better heat management. The inclusion of Kevlar fiber also adds durability compared to standard options. This makes them a solid upgrade for riders who want reliable performance without moving to a noisy full-metallic pad.

Questions and Answers

Question: Will these pads fit my Shimano M520 brakes?

Answer: These pads are designed for calipers with the E10.11 shape, which includes models like HD-M520, M521, M510, M500, and M501. They are not for standard Shimano M520 mountain bike brakes, which use a different pad shape.

Answer: Lifespan depends on riding conditions and frequency, but the semi-metallic material with Kevlar fiber is designed to last about twice as long as standard resin pads.

Question: Are these pads noisy during braking?

Answer: They are designed for low noise operation compared to full-metallic pads. The semi-metallic compound helps reduce squealing while still providing strong stopping power.

Question: Can I use these pads on a road bike?

Answer: Yes, these pads are suitable for road bicycles that use compatible hydraulic disc brake calipers with the E10.11 pad shape.

Question: Do these pads require any special installation tools?

Answer: No special tools are needed beyond standard bike maintenance tools. Installation is straightforward for anyone comfortable working on their bike's brakes.
