Shimano Hydraulic Disc Brake Caliper BR-MT620 4 D03S

»Two-part construction: rigid and durable design. »Four pistons: 4-piston design with different diameters, providing high power and control. »Thermal stability: the new low-viscosity oil, new piston seal and heat-resistant resin piston ensure stable performance over a wider temperature range. »Pad compatibility: works perfectly with metal or resin pads without fins. »Off-series option: same features as DEORE M6220 calipers, but with a different aesthetic finish. The MT620 four-piston hydraulic disc brake calipers offer powerful and consistent braking regardless of the conditions of use. Designed around a rigid two-part structure, they provide better bike control thanks to their new low-viscosity oil, new piston seals, and heat-resistant resin pistons, allowing the braking system to remain stable over a wide temperature range. The calipers are compatible with metal or resin pads without fins, as well as standard or thicker 2.2 mm discs.
