Product Information

Full details

The EBC X-Series floating brake disc (MD3115X) is designed for performance-oriented motorcycle riders seeking improved braking responsiveness and superior heat management. By utilizing a floating disc construction, it offers the advantage of optimal thermal expansion during intense braking sessions, though riders should note that this type of performance component requires specific installation precision to ensure safety and longevity.

FAQs

Why do floating discs make a slight noise?

Floating discs have a small amount of movement between the rotor and the inner carrier; this is a normal characteristic of the design.

Can I use my old brake pads with the new MD3115X disc?

It is strongly recommended to use new brake pads to ensure an even bedding-in process and to avoid damaging the new rotor surface.

How often should I check the floating buttons?

Inspect them during every tire change or at least once every 5,000 miles to ensure they are clean and moving freely.

Does this disc fit all motorcycle brands?

No, the MD3115X is a specific part number; please check your specific motorcycle model year and compatibility chart before purchasing.

Do I need special tools to install this?

You will need a high-quality torque wrench, proper size hex or torx bits for the rotor bolts, and thread-locking compound.

Troubleshooting

Brake judder during light braking

Check for debris caught in the floating buttons or ensure the disc is fully seated and bolts are torqued evenly.

Clicking sound from the front wheel

Minor movement in the floating buttons is normal, but if the sound is excessive, inspect for worn hardware.

Inconsistent braking feel

Bleed the brake hydraulic system to remove air bubbles and verify the disc surface is free of contamination or oil.

Pros and Cons

Pros

  • Superior heat dissipation compared to fixed rotors
  • Reduces risk of brake fade during demanding riding
  • Provides enhanced braking feedback and control
  • Floating design accommodates thermal expansion
  • High-grade durability for long-term performance

Cons

  • More complex installation than standard discs
  • Requires professional or experienced mechanical knowledge
  • Periodic inspection of floating hardware is necessary
  • More expensive than entry-level aftermarket discs

Setup, Compatibility & Care

To install the MD3115X, ensure your hub surface is clean and free of debris. Always use new high-strength rotor bolts and apply the recommended thread-locking compound. Check your motorcycle's service manual for specific torque specifications, as over-tightening can compromise the floating mechanism. For maintenance, keep the buttons (the fasteners connecting the rotor to the carrier) clean; a periodic wipe down with brake cleaner is advised to prevent debris buildup that could restrict the disc's natural float. Always pair new rotors with new, high-performance brake pads to ensure even bedding-in.
