Hope Tech Evo GR4 Rear Brake

Engineered for maximum control and stopping power, the Hope Tech Evo GR4 Rear Brake sets a new benchmark in gravity and e-bike performance. Featuring a refined four-piston caliper, precision-machined construction, and an advanced lever design, the GR4 delivers smooth modulation, firm bite, and unmatched reliability on the toughest terrain.

Uncompromising Performance

Built to handle the most demanding downhill and enduro conditions, the Tech Evo GR4 provides consistent braking feel and exceptional fade resistance. Its upgraded cam mechanism and precision piston alignment deliver instant feedback and balanced power through every corner and descent.

Lever Blade Options

Choose from three lever blade profiles to match your preferred feel and setup:

• Standard (STD): The perfect balance of power, control, and adjustment — ideal for most riders and conditions.
• Power: Designed for riders who run levers further from the bars. Offers 5mm more outward adjustment and increased leverage for extra braking force.
• Control: Shorter blade optimized for levers positioned closer to the handlebars. Maintains a natural feel with tighter ergonomics.

Blade Design & Feel

All Evo lever blades feature an enhanced hook profile for superior grip and control during aggressive descents. The dimpled contact surface improves comfort and traction, even in wet or muddy conditions. Each lever also provides independent reach and bite point adjustment for a fully personalized setup.

Cam Mechanism

The new cam design reduces free lever stroke while maintaining modulation and feel within the braking zone. The result is a firmer initial bite followed by a smooth, predictable increase in power — giving riders more control on technical terrain and steep descents.

Piston Technology

Featuring a roller bearing main pivot and dual guide bush system, the Tech Evo GR4 ensures perfectly straight piston movement and friction-free lever action. This results in buttery-smooth operation and enhanced lever consistency, even under heavy load.

Streamlined Bleeding System

Hope has introduced a new bleed port directly into the master cylinder, simplifying maintenance and reducing downtime. The system supports both a quick closed-bleed or a traditional open-bleed method. Internal porting has been redesigned to eliminate trapped air and ensure a faster, cleaner bleed process.
