Hope Tech 4 EVO GR4 Hydraulic Disc Brake - Silver / RedRear Left HandBraided

The Hope Tech 4 EVO GR4 Hydraulic Disc Brake is built to deliver maximum stopping power in the toughest gravity and e-bike conditions. With a new cam mechanism, four hybrid pistons, and a stiffer one-piece caliper, it provides unmatched braking strength while keeping control precise and natural. Premium construction and smooth lever action ensure reliable performance on every ride.Key Features and Benefits:New cam mechanism with reduced free stroke: This design shortens the initial lever movement, giving faster pad engagement. The benefit is more predictable braking response, resulting in greater confidence when applying power.Secondary guide bush for piston alignment: The added guide bush keeps each piston running straight in the caliper. This reduces friction and ensures smoother movement, which leads to more consistent braking under load.Integrated bleed port in master cylinder: The added port allows bleeding without removing the lid. This makes servicing faster and cleaner, ensuring reliable performance with less downtime.One-piece machined caliper: Machined from a single block, the caliper is lighter and stiffer than multi-piece designs. This stiffness improves power transfer and braking accuracy, giving the rider better control.Four hybrid pistons for heat management: The caliper uses hybrid piston technology to balance power and cooling. This reduces heat build-up and maintains smooth lever feel, even on long descents.Largest piston size for maximum force: Oversized pistons generate more clamping power, increasing brake force by 6% compared to the Tech 4 V4 system. This extra ratio translates into stronger stopping ability for demanding terrain.Revised bore cap for frame clearance: The updated design reduces caliper width. This allows better fitment on modern frames, preventing clearance issues without sacrificing strength.Stiffer caliper for improved modulation: The increased stiffness not only boosts raw power but also enhances feedback at the lever. The result is precise control over braking pressure in technical sections.Reliable braking performance depends on more than raw power. The Tech 4 EVO GR4 combines large four-piston calipers, efficient heat management, and smooth lever action to provide strength that does not compromise modulation. These features work together to deliver control and consistency in conditions where dependable braking matters most.Choose the Hope Tech 4 EVO GR4 Hydraulic Disc Brake for a system that pairs maximum stopping force with smooth, predictable handling. Built for gravity and e-bike use, it is engineered to perform when you need it most.Rotors Not included.
