Shimano Deore Front/Rear Hydraulic Disc Brake

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.

ICE TECHNOLOGIES
SHIMANO ICE TECHNOLOGIES components deliver more consistent braking performance by reducing heat buildup in the system. This helps prevent brake fade, which can happen when a rider applies the brakes repeatedly and strongly over a short period of time, such as when descending a long, steep hill.

ONE WAY BLEEDING
“ONE WAY BLEEDING” was developed for quick and easy prevention of air in our hydraulic system. We 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.
