Four-piston trail brake for medium-duty use.

- New cam mechanism designed to decrease the free lever stroke while maintaining feel and modulation in the braking zone
- Piston movement – Additional secondary guide bush to keep the piston running perfectly straight to maintain super smooth piston movement.
- Bleeding – A bleed port has been added to the master cylinder body to allow bleeding without removing the lid.
- One piece machined caliper for reduced weight and increased stiffness
- Four hybrid pistons allow smooth movement and excellent heat management
- Larger pistons for the increased power
- The larger pistons increase the ratio of the brake by 6.5% when compared to Tech 4 E4 brake system
- Revised bore cap design reduces width for more frame clearance
- Larger pad improves lever feel and consistency
- Choose this caliper for power balance with a firm lever feel and excellent braking control





























Cam Mechanism
A new cam designed to decrease the free lever stroke while maintaining the feel and modulation in the braking zone — a key feature of the Tech 4 brakes.
The result is a slightly firmer feel at the bite point, followed by a gentle rise in power through the braking zone, further enhancing brake modulation.

Piston Movement
Roller bearing main pivot is carried over from Tech 4 along with sliding guide bush on the main piston.
Additional secondary guide bush keeps the piston running perfectly straight to maintain super smooth piston movement throughout the full lever travel.

Bleeding
A bleed port has been added to the master cylinder body to allow bleeding without removing the lid, simplifying and streamlining the process. The classic "open" bleed option is retained for the ultimate bleed.
The internal port design has been reworked to eliminate air pockets during bleeding and to support a more consistent bleed process.
