These Aztec Organic Disc Brake Pads are for cyclists riding in UK conditions, offering reliable braking power in wet and muddy environments. While providing excellent performance, they may wear faster than semi-metallic or metallic options in extreme conditions. These pads are designed as direct replacements for Shimano Deore M515/M525 calipers, featuring an organic compound for consistent stopping power and a stiff, corrosion-resistant backing plate for durability.

Yes, these pads are specifically designed for UK riding conditions, offering good performance in wet, muddy, and variable weather. They perform reliably across a range of temperatures.
Pad life depends on riding style, conditions, and terrain. Inspect your pads regularly. When the pad material wears down to about 1mm, it's time for replacement.
Organic pads (like these) offer quieter operation and better modulation, especially in the wet. Metallic pads generally offer higher heat resistance and longer life in dry, dusty conditions but can be noisier and less effective in the wet.
Yes, a bedding-in process is highly recommended to ensure optimal braking performance and longevity by creating a consistent transfer layer between the pad and rotor.
These pads are designed for M515 and M525 calipers. While some compatibility may exist with other Shimano models, it is best to confirm the exact pad shape required for your specific M615 caliper model.
For extreme downhill riding with prolonged high-heat braking, metallic pads might offer better fade resistance. These organic pads are excellent for general trail riding and everyday use but may not be ideal for the most demanding downhill applications.
If contaminated with oil or grease, clean the pad surface and rotor with isopropyl alcohol and a clean, lint-free cloth. Avoid using household cleaners. If contamination is severe, pad replacement may be necessary.
Ensure the brake pads are properly seated and that the brake system has been recently bled if hydraulic. Check for rotor contamination and clean if necessary. Perform the bedding-in procedure again.
This can sometimes occur with organic pads. Ensure the pads and rotor are clean. Check that the pads are not excessively worn. A slight glaze on the pad surface might require re-bedding or light sanding of the pad surface.
Check pad wear – if worn too thin, they will not engage the rotor properly. Inspect the brake fluid level (if hydraulic) and check for leaks. Ensure the caliper pistons are moving freely.
Clean the rotors and pads. Water can sometimes carry contaminants. Re-bed the pads if performance has significantly degraded.
Compatibility:
These brake pads are specifically designed as replacement or upgrade pads for brake calipers compatible with Shimano Deore M515 and M525 systems. Always confirm your existing brake caliper model before purchasing.
Setup:
Bedding-in Process:
For optimal performance, a bedding-in procedure is recommended. Ride the bike at a moderate speed and apply the brakes firmly but without locking the wheels, repeating this 10-15 times. Allow the brakes to cool completely between runs. This process transfers a thin layer of pad material to the rotor, ensuring consistent braking.
Care:
Keep brake rotors clean and free from oil or grease. Periodically inspect pads for wear. Clean the pads and rotors with isopropyl alcohol and a clean cloth if they become contaminated. Store the bike in a dry place to prevent unnecessary corrosion.
