Shimano BR-MT620 Brake Caliper - Post Mount | 4-Piston | front/rear

While two pairs of pistons with different diameters help the BR-MT620 brake caliper deliver not only a powerful but also consistent braking performance, its two-piece construction enhances stiffness and long-term durability. At the same time, the use of Shimano’s reformulated, low-viscosity mineral oil, combined with heat-resistant resin pistons and optimized gaskets, ensures better and more consistent braking power control across a wide temperature range.

Same technology, different finish. In terms of its functional features, the BR-MT620 is on par with the 4-piston caliper from the Deore M6200 series (BR-M6220), but stands out visually with a solid black appearance.

SERVOWAVE | This braking system manages the friction between the brake pads and the rotor throughout the entire lever travel to achieve an optimized power curve and correspondingly more balanced braking performance. The SERVOWAVE brake lever covers a significant portion of the travel at the beginning of its movement, allowing the brake pads to be brought into contact with the rotor with minimal lever travel. Once the brake pads make contact, the force transmission ratio increases rapidly. The majority of the lever travel is thus still available to increase braking force and modulate it more precisely.
