Product Information
Full details
The Hope Tech 4 V4 is an elite hydraulic disc brake system designed for aggressive enduro, freeride, and downhill mountain bikers who demand maximum stopping power and precision. With a 30% increase in braking pressure over the previous Tech 3 model and a refined lever design that utilizes roller bearings for a lighter, smoother pull, this system significantly reduces rider fatigue on long descents; however, due to its advanced engineering and high-performance requirements, it is best suited for experienced riders or those comfortable with professional-grade bike maintenance.

FAQs
Does the Hope Tech 4 V4 come with rotors?
No, the Tech 4 V4 lever/caliper system is typically sold without rotors, allowing you to choose the specific size and type that fits your frame and riding style.
Can I use these brakes with standard shifters?
Yes, the Tech 4 V4 is designed with improved shifter integration to ensure a clean cockpit layout regardless of your shifting setup.
How often should I change the brake fluid?
It is recommended to bleed your brakes and replace the fluid at least once a year, or more frequently if you ride in very aggressive or muddy conditions.
Are the pads included?
Yes, the system is supplied with high-performance racing compound pads installed, ready for use.
What is the benefit of the phenolic inserts in the pistons?
Phenolic inserts act as a thermal barrier, significantly reducing the amount of heat that transfers from the brake pads into the hydraulic fluid during extreme braking.
Troubleshooting
Lever feels 'spongy' or soft
This usually indicates air in the hydraulic system. Perform a full bleed using a proper bleed kit to remove trapped air.
Brakes are squealing during use
Check if the pads or rotor have become contaminated with oil or grease. Clean the rotor with isopropyl alcohol and sand the pad surface lightly, or replace the pads if fully contaminated.
Pistons are not retracting fully
Clean the pistons carefully with a lint-free cloth and a small amount of brake fluid. Ensure no dirt or brake dust is causing the pistons to bind.
Pros and Cons
Pros
- Significantly higher braking power than the previous generation
- Excellent modulation and lever feel thanks to roller bearings
- Tool-free adjustment makes setup highly convenient
- Superior heat management for long, aggressive descents
- High-quality CNC-machined construction
Cons
- Requires technical skill for bleed procedures and maintenance
- Higher price point reflecting premium engineering
- Aggressive power may be overkill for light cross-country riding
Setup, Compatibility & Care
Proper setup is essential to get the most out of your Tech 4 V4 brakes. Ensure your bike frame and fork have post-mount or compatible adapters to fit the V4 caliper. When installing, take care to center the caliper over the rotor to prevent pad drag.
Maintenance Tips:
- Bedding-in: The provided racing compound pads require minimal bedding-in, but perform a few short, firm stops on a safe, flat surface before heading to the trails.
- Bleeding: Only use genuine fluid as recommended by Hope. Use a dedicated bleed kit to ensure no air bubbles remain in the lines.
- Cleaning: Use only mild soap and water to clean the calipers. Avoid harsh chemical degreasers that could damage the seals or contaminate the pads.
