D-4 Hydraulic Oil Brake Handles & 4?Piston Calipers

Overview

The D-4 is a hydraulic brake set that pairs ergonomic oil-filled brake handles with four-piston calipers for predictable, strong stopping power. Designed for trail and commuter bikes, it aims for consistent performance, simple setup, and low maintenance.

Benefits

Improve control and confidence when slowing or stopping—more modulation and bite from the four-piston calipers.
Spend less time on maintenance thanks to a sealed mineral-oil system and tool-free pad adjustment.
Quickly tailor the lever feel to your hand size and riding style with adjustable reach and modular pads.
Reduce fuss during installation with pre-bled hoses and a complete mounting kit.
Reliable performance in wet or mixed conditions so you can ride more consistently.

Features

Hydraulic actuation using mineral oil for stable, low-maintenance braking.
4-piston calipers for increased stopping force and heat distribution.
Ergonomic brake handles with adjustable lever reach and bite point tuning.
Pre-bled hoses and compression fittings for faster installation.
Tool-free pad adjustment and a quick pad-change system.
Compatible with 160–203 mm rotors and standard post-mount frames/forg?es (adapters included).
Replaceable sintered and organic pad options included in the kit.
