Features: Material: Aluminium painted Use: MTB Piston: 2-piston Caliper Mount: Post Mount Type: Hydraulic disc brake Pads: G03A Resin without fin Hose Connection: Banjo Brake Fluid: Mineral oilRecommended Lever: BL-M8100Technologies: Ice Technologies: The fade, which can occur to disc brake rotor and pad when braking on a long downhill ride, has a negative impact on the braking performance. Shimano has adopted Ice Technologies disc brake rotor and Ice Technologies pad to realise the cooling technology for consistent performance. The clad disc brake rotor blade, which has a 3 layer-sandwich structure of stainless steel, aluminium and stainless steel, provides better radiation performance achieving from 400˚C to 300˚C surface temperature. Also, the radiation fin has been adopted for the pad. Moreover, the clad disc brake rotor blade and the radiator fin provide long pad life, less noise, less fade and lightweight. 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.
