Shimano Deore BR-M6220 4-Piston Brake Full-power braking, dialed-in control. The Shimano Deore BR-M6220 is a complete hydraulic disc brake set that pairs the four-piston BR-M6220 caliper with the BL-M6200 lever for a capable, reliable braking system at an accessible price point. The dual-diameter four-piston caliper delivers high power and excellent modulation, while new low-viscosity mineral oil, an updated piston seal, and a heat-resistant resin piston keep performance consistent across a wide range of temperatures. The BL-M6200 lever adds SERVO WAVE technology for rapid initial pad contact and a progressive power curve, plus I-SPEC EV compatibility for clean on-bar integration with compatible Shimano shifters. Features Dual-diameter four-piston caliper uses differently sized pistons to prevent rotor wobble, reduce noise, and deliver high stopping power with excellent modulation SERVO WAVE lever technology provides rapid initial pad travel to bring pads into contact quickly, then increases braking power through the rest of the stroke for strong, controlled stops Temperature stability comes from a combination of new low-viscosity oil, an updated piston seal, and a heat-resistant resin piston for consistent feel in varying conditions Two-piece caliper construction provides a rigid, durable body built to handle demanding trail use Broad pad compatibility works with both non-finned metal and resin pads, and supports both standard and thicker 2. 2mm rotors I-SPEC EV lever compatibility allows on-bar integration with compatible Shimano shifters and a wide range of lever position adjustability Clean lever aesthetic routes the hydraulic hose parallel to the bar for a tidy cockpit appearance SPECIFICATIONSLever Model BL-M6200Caliper Model BR-M6220Brake Type Hydraulic disc Piston Count4-piston (dual-diameter)Caliper Construction Two-piece Fluid Type Shimano low viscosity mineral oil Pad Compatibility Non-finned metal or resin pads Rotor Compatibility Standard and 2. 2mm rotors Lever Mount I-SPEC EV compatible / Clamp Intended Use Trail, MTB | Shimano | Deore Br-M6220 4-Piston Brake Right/rear, 1700Mm Hose, Metallic Pads
