shimano deore br-m8020 xt 4 pot calliper front or rear disc brake

High performance hydraulic disc brake for efficient braking in all conditions.Features:Front or rear wheel use for international standard or post mount with adapters (not included)4 oversized phenolic pistons optimized for heat insulation, lightweight and stiffnessOpposed 4-piston design reduces leading effect and optimal pad wear increases braking controlIncreased pad to rotor clearance reduces the chance of rotor drag in muddy conditionsForged calliper design is lightweight and rigidOne way internal fluid circuit makes bleeding easyMineral oil brake fluid is non-corrosive and less hazardous than conventional hydraulic brake fluidShim-less mounting bracket allows for quick installation and setting upRecommended for use with ice tech centre-lock rotors for optimum braking performanceComes with g02a resin pads without finsCan be used with ice tech pads available in resin or sintered compound, the optional aluminum radiation fin pad further improves heat dissipation reducing brake surface temperature by 50 deg c
