The 4-piston, 2-piece BR-M8220 caliper is the strongest in the M8200 family, designed to increase power, consistency, and control.
New, low viscosity oil keeps the M8220 brakes' bite point consistent in all trail and weather conditions. New brake pads eliminate rattling noise caused by vibration, providing riders with pinpoint control on rough trails.
The fade, which can occur to disk brake rotor and pad when braking on a long downhill ride, has a negative impact on braking performance. SHIMANO has adopted ICE TECHNOLOGIES disk brake rotor and ICE TECHNOLOGIES pad to realize cooling technology for consistent performance. The clad disk brake rotor blade, which has a 3-layer sandwich structure of stainless steel, aluminum, and stainless steel, provides better radiation performance. Additionally, a radiation fin has been adopted for the pad. The clad disk brake rotor blade and radiator fin provide long pad life, less noise, less fade, and lightweight.
A disk brake system with a dual diameter opposed-piston caliper design has differently sized pistons in front and in the rear. The system adopts a power transfer system in which the disk brake rotor is pressed by the smaller sized piston at the entrance of the disk brake rotor intake and also by the more powerful larger sized piston at the back. This prevents wobbling motion of the disk brake rotor and reduces noises significantly. The 4-piston caliper also allows a wider contact area for the disk brake rotor while keeping the size compact, and the efficient location of pads is adjusted as necessary to stabilize the pressure. In combination use with the SERVOWAVE lever, it provides an incredible 50% more stopping power than the previous model. The advanced SAINT/ZEE disk brake system, which adjusts to accommodate the different braking styles of different riders, offers stable braking power and excellent modulation.
Features:
- Updated seals and low viscosity oil ensure a reliable bite point in all temperatures and trail conditions.
- Predictable power with a DH-capable power curve, perfected for the rigors of enduro racing and all-day trail riding.
- Heat dissipation: Resin or metal pads, finned or non-finned, allow riders to tune their precise brake feel when paired with SHIMANO rotors.
- Rattle-free: Revised pad and oval mount eliminate unnecessary noise.
