The Hope Tech 4 EVO GR4 Hydraulic Disc Brake is engineered for gravity, downhill, and E-bike riders needing maximum stopping power and control in extreme conditions. Its key benefit is a significant increase in braking force and heat management due to a four-piston, one-piece caliper design and updated lever mechanics. A potential caveat is that rotors are not included and must be purchased separately.

The GR4 caliper increases the braking ratio by 6% over the V4 system, offering greater braking force and improved heat management due to its larger piston size and one-piece construction.
Yes, rotors are not included with the Hope Tech 4 EVO GR4 Hydraulic Disc Brake and must be purchased separately.
This brake system is specifically engineered for gravity, downhill, and E-bike applications where maximum stopping power and control are essential.
The system features an integrated bleed port in the master cylinder for easier maintenance. Refer to the official Hope manual for detailed, step-by-step bleeding instructions using the correct hydraulic fluid.
While aftermarket pads may fit, it is highly recommended to use genuine Hope replacement pads to ensure optimal performance, compatibility, and longevity of the braking system.
The redesigned cam mechanism reduces the free lever stroke, providing a more immediate and responsive brake engagement for better control.
The product description specifies 'Right Hand', which typically refers to the rear brake lever in most countries. However, lever orientation can be customized, and it's essential to confirm for your specific setup.
The brake system likely needs bleeding. Follow the manufacturer's instructions to bleed the hydraulic system, ensuring all air is removed. Check for any leaks in the hose or fittings.
Inspect the brake pads for wear and contamination. Clean the rotor surface. If the issue persists, perform a full brake bleed and check for any restrictions in the brake line.
Adjust the lever reach using the adjustment screw. If free stroke remains excessive, the system may require bleeding, or there could be wear in the lever's master cylinder or caliper seals.
Clean the rotors and pads. Ensure pads are properly bedded in. Check for rotor runout or contamination. If using new pads, ensure they are fully bedded.
Center the caliper over the rotor by loosening the mounting bolts, squeezing the brake lever firmly, and retightening the bolts. Ensure the rotor is true and not warped.
