High power 4 piston Deore M6220 brake caliper providing efficient braking with a minimalist design.
The Deore M6220 hydraulic four-piston disc brake calipers bring consistent and full-power braking to the line. The calipers are built around a rigid two-piece design and offer better bike control through their new low-viscosity oil, new piston seal and new heat-resistant resin piston, allowing the braking system to stay stable over a wide range of temperatures. The calipers are compatible with non-finned metal or resin pads and both regular and thicker 2.2mm rotors.
Technology
Four Piston
Disc brake system with the 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 disc brake rotor is pressed by the smaller sized piston at the entrance of the disc brake rotor intake and also by the more powerful larger sized piston at the back. This prevents the wobbling motion of the disc brake rotor and reduces noises significantly.
The 4-piston caliper also allows a wider contact area for the disc 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 Servo Wave lever it provides an incredible 50% more stopping power than the previous model. The advanced Saint / Zee disc brake system, which adjusts to accommodate the different braking styles of different riders, offers stable braking power and excellent modulation.
- Dual diameter opposed 4-piston caliper design
- Offers stable braking power and excellent modulation, and disturbs the wobbling motion of the rotor and reduces noises significantly
One Way Bleeding
"One Way Bleeding" was developed for quick and easy prevention of air in Shimano's hydraulic system. Shimano have streamlined the oil route throughout the system to prevent air bubbles from being captured in the system.
One way oil routing plus a funnel tool with mineral oil provides an easy and clean bleeding system.
Features
- Two-piece Construction: Rigid, durable design
- Four-piston: Dual-diameter 4-piston design, offering high power and control
- Temperature Stability: New low-viscosity oil, new piston seal and new heat-resistant resin piston result in stability over a wider range of temperatures
- Pad Compatibility: Works seamlessly with non-finned metal or resin pads
- The one way internal fluid circuit makes bleeding easy, while great piston retraction increases pad to rotor clearance
- Shim-less mounting bracket allows for quick installation and set up
- Compatible with international standard and post mount forks
- To be used in conjunction with Shimano hydraulic brake levers
- Can be used with Ice Tech pads available in resin or sintered compound, the optional aluminium radiation fin pad further improves heat dissipation reducing brake surface temperature by 50°C
- Comes as standard with D03S resin pads
