Hope Tech 4 Evo TR4 Braided Disc Brake - Black / Colours
The Tech 4 Evo TR4 delivers 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. Four-piston trail brake for medium-duty use. The ultimate trail-riding brake impressive power balanced with a firm and consistent lever feel. Super-smooth lever actuation provides excellent braking feedback for absolute control.
Lever 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.
