This is a complete front hydraulic disc brake set with a four-piston caliper and right-hand two-finger lever. The additional pistons increase pad contact area for strong, controlled braking, while the compact caliper keeps the installation neat on a compatible post-mount fork.
The dual-diameter opposed-piston layout helps distribute pressure across the rotor, supporting consistent braking feel while reducing rotor wobble and brake noise. Compared with the current two-piston MT400 system, the published performance data shows a 20% increase in braking power and 150% better wear resistance. The system also delivers 90% of the braking power of BR-MT520.
Servicing is straightforward with funnel bleeding, a streamlined oil route and Shimano mineral oil. The supplied SM-BH90-SS hose has a straight joint, and the resin pads are supplied without fins. Check your fork mounting standard and rotor setup before ordering; the caliper is designed for a post-mount fork and does not require an adapter.
A practical choice for MTB riders upgrading from a two-piston front brake who want more stopping power and control for trail, enduro, e-MTB or steep-descending use.
Four-piston stopping power
More piston area supports stronger braking and confident speed control on steep or technical terrain.
Controlled braking feel
The dual-diameter opposed-piston design helps stabilise rotor pressure for predictable application and reduced noise.
Right-hand front setup
Configured as a front brake with a right-side lever for straightforward replacement or bike-build installation.
Small-hand-friendly reach
The two-finger lever offers an accessible minimum reach of 75 mm.
Post-mount installation
Designed to mount directly to a compatible post-mount fork without an adapter.
Clean hydraulic servicing
Funnel bleeding and the streamlined oil route help make bleeding quicker and help prevent air entering the system.
Durable resin pads
Resin pads provide the supplied braking compound, with the pad and piston construction supporting improved wear resistance.
Mineral oil system
Uses Shimano mineral oil for the hydraulic circuit and consistent day-to-day operation.

Generic is a catalogue designation for products presented without a distinct store-brand identity. The term describes the retail classification rather than a separate manufacturer history or geographic origin. Generic-labelled products can still have clearly defined specifications, standards and compatibility requirements. For this component, the catalogue designation is retained while the fitment details identify the relevant road bottom bracket application.
