This 4-piston trail brake is built for medium-duty use, delivering an ideal balance of power and control. A firm, consistent lever feel pairs with smooth actuation to give precise braking feedback, making it a reliable choice for trail riders who demand confidence on any terrain.

Features

• Cam Mechanism
  The updated cam design shortens the free lever stroke while preserving consistent feel and modulation through the braking zone. Riders get a firmer bite point with a steady increase in power for improved control.
• Piston Movement
  Using a roller bearing main pivot and a sliding guide bush, the piston moves smoothly and precisely. A secondary guide bush keeps the piston straight, ensuring reliable, friction-free lever travel throughout its range.
• Bleeding
  A bleed port on the master cylinder makes servicing simpler by allowing fluid changes without removing the lid. The revised internal layout reduces the risk of air pockets, helping deliver a more consistent and dependable bleed process.
• Caliper Desigh
  The one-piece caliper body provides excellent stiffness while keeping weight low, ensuring reliable performance under load. Larger pistons boost braking power and ratio, while the shared pad size with the GR4 caliper delivers consistent lever feel and feedback. A slimmer bore cap reduces overall width, improving frame clearance and compatibility without compromising strength.
