The hydraulic Shimano BR-MT420 disc brake caliper with post mount has an extremely slim structure despite its 4-piston design. The 4 pistons made of resin (synthetic resin) offer 20% more braking power than the 2-piston version and guarantee reliable deceleration and control in downhill use. Wear resistance has also been increased by 150% compared to the BR-MT400 caliper.
