Trail-proven power with balanced modulation. The one-piece TR4 caliper with larger pistons and shared GR4 pads delivers a 6.5% increase in braking ratio over the previous E4 system—ideal for trail and all-mountain use.
EVO Master Cylinder: The Master cylinder features a new cam mechanism to reduce free stroke while maintaining the feel and modulation, a key feature of the much-loved Tech 4. The piston assembly—features a secondary guide bush and sliding guide—ensures ultra-smooth operation throughout the full lever stroke.
EVO Calipers: The caliper bodies have been refined for greater stiffness, improved hub/frame compatibility, and streamlined profiles. Bore cap designs are optimized to reduce width and improve fit across modern frame geometries.
Key Updates
-
Optional Control and Power Lever Blades, shaped for riders who prefer their brakes to bite at the extremes of the lever adjustments.
- Control: For riders who run their bite point close to the bars.
- Power: Bite point further out.
- Redesigned lever with more pronounced hook and dimples for more confidence in wet or cold conditions.
- New cam design and piston provide a firmer bite point and more feel.
- Upgrades to the lever bearing and piston add to the T4's already incredible feel and consistency.
- Clean, simplified bleeding thanks to a new bleed port in the master cylinder.
- Caliper tweaks enhance the consistency of performance as the pads wear.
- Larger pistons than E4 increases the braking ratio by 6.5%.
- Larger pads than E4 improves lever feel and consistency.
- Improved caliper stiffness.
- Lower profile shape with new bore cap design for more clearance.
