Rectangular "Ears" 4-Piston Brake Pad (Shimano M02/M03/M04)

• These pads suit:
  • TurboBrake HB427-4M calliper and Teverun Fighter models that adopt that same calliper.
  • As drop-in replacement for other callipers that adopt Shimano M02 & M04 (Resin) and M03 (Metal) pads.
• Supplied as a set (pair) two pads, one for each side. Order two sets for both front and rear.
• Available in two compounds:
  • All-Metal (Gold): Our recommended pad, identical compound to that factory-fitted in HB427-M. Available as:
    • ULIP factory spare (includes pin).
    • TurboBrake factory OEM spare (without pin, as shown in product image).

The only difference between the two is the brand/manufacturer and inclusion of the pin.

• Ceramic (Green) which is a good option for where All-Metal pads may omit excessive noise, such as in dusty/dirty environments. Includes pin as shown in product images.

To further understand merits of each compound, refer to the Reference Materials for Brake Pads page.

• In addition to inclusion of pin on select variants, all versions include retaining spring. If your calliper has a screw (such as HB427-M) rather than split pin, retain the screw.
• Observed plate width of 41.5mm vs 39.5mm on Rectangular "Logan" 4-Piston Brake Pad (Shimano D02S/D03S).

Notes

1. The "ears" pads are slightly wider than the Rectangular "Logan" 4-Piston Brake Pad (Shimano D02S/D03S), making them a more appropriate fit than the "Logan's" where callipers are designed for the additional width. The "ears" help retain position within the calliper.
2. Teverun Fighter Supreme initially adopted the HB427-4S calliper with a finned pad (shown in first image). Those pads adopts the shape of the Rectangular "Logan" 4-Piston Brake Pad (Shimano D02S/D03S), but with a heatsink which differs in appearance to the NUTT Finned pads). Later models across the flagship / higher end models (ULTRA, 7206R etc) adopt the HB427-4M calliper with this "ears" pads, shown on right/below.
   
3. Those running TurboBrake systems typically do not get a lot of noise out of the All-Metal as the HB427-4M has good heat management and the Wave Slotted rotor design which helps hot gasses escape.
