Shimano BR-MT600 2-Piston Brake Caliper Lighter stopping power, same reliable bite. The Shimano BR-MT600 is a two-piston hydraulic disc brake caliper built for riders who want to trim weight without giving up consistent, controllable stopping power. It delivers the same modulation and temperature-stable performance as the four-piston M6220 caliper, but in a lighter package. New low-viscosity mineral oil, an updated piston seal, and a heat-resistant resin piston work together to keep braking feel stable across a wide range of temperatures. Compatible with both resin and metal pads, and shares the same technology as the Deore M6200 caliper line with a different cosmetic finish. Features Two-piston design prioritizes weight savings and modulation for riders who want a lighter brake setup without sacrificing control Temperature stability comes from a combination of new low-viscosity oil, an updated piston seal, and a heat-resistant resin piston for consistent performance in varying conditions Two-piece construction provides a rigid, durable caliper body built to handle demanding trail use Broad pad compatibility works with both non-finned metal and resin brake pads Non-series option shares the same technology and features as the Deore M6200 caliper with a different cosmetic finish SPECIFICATIONSModel BR-MT600Piston Count2-piston Construction Two-piece Fluid Type Shimano low-viscosity mineral oil Pad Compatibility Non-finned metal or resin pads Intended Use Trail, XC | Shimano | Br-Mt600 2-Piston Brake Caliper Caliper Only, With G05S-Rx Resin Pads
