Hope V4 vs GR4 vs TR4 – The Complete Guide for Riders

Are you wondering what’s changed between the Hope V4 and the new GR4 and TR4 brakes? You’re not alone. With Hope’s launch of the EVO series, riders everywhere are asking if the V4 is being discontinued, which rotors still fit, and how to get the right brake pads. This guide from Gorilla Brakes breaks down everything you need to know — straight from real-world testing and expert analysis.

1. From V4 to EVO: A New Era for Hope Brakes

Hope’s V4 has long been the powerhouse of the Tech 4 lineup — known for its unmatched stopping power, rock-solid reliability, and vented rotor compatibility. But in 2025, Hope introduced the EVO range, featuring the GR4 and TR4 models, which refine and replace the outgoing V4 in performance and design.

The GR4 and TR4 are built around a stiffer one-piece CNC-machined caliper and an improved Tech EVO lever. The design goal? Deliver more power, more consistency, and smoother modulation while keeping Hope’s signature serviceability intact.

What’s new in the EVO generation:

• Increased piston surface area for up to 6% more braking force than the V4.
• Stiffer lever body with reduced free stroke for a sharper feel.
• Refined bleed port and lever bushing for easier maintenance.
• Simplified caliper design with improved heat management.

2. Can GR4 Use Hope’s Vented Rotors?

This is one of the most common questions we hear — and the answer is no.

The GR4 is not compatible with Hope’s vented rotors. Hope made this decision intentionally to keep the caliper body narrower and stiffer. By removing the extra clearance required for vented rotors, the GR4 achieves better rigidity and lever feel. The same applies to the TR4 — it also cannot use vented rotors.

The V4, however, can use Hope’s 3.3 mm vented rotors, which are ideal for long descents or e-MTB use where extreme heat management is key. So, if you’re already running vented rotors and love their feel, staying with V4 remains a strong option.

3. Brake Pad Compatibility — Simplified by Gorilla Brakes

Here’s some great news: despite the caliper updates, the V4, GR4, and TR4 all use the same brake pad shape. That means you can switch between these calipers without worrying about new pad types or sizing issues.

Gorilla Brakes has made it even easier with a dedicated collection that covers all three models. Whether you’re replacing worn pads or upgrading to a higher compound, our pads are precision-matched to fit every Hope 4-piston caliper in this series.

Available Compounds:

• Enduro Pro – Race-ready sintered compound for aggressive downhill and e-MTB use.
• Factory Racing – Semi-metallic blend offering perfect modulation and heat control.
• Standard – Everyday reliability for XC, trail, and commuting.

Each compound is tested in real riding conditions, delivering predictable bite, minimal fade, and long pad life — no matter what terrain you ride.

5. Which Hope Brake Should You Choose?

Stick with the V4 if:

• You already own vented rotors and want to keep using them.
• You prioritise heat dissipation for long descents.
• You like the V4’s softer initial bite and traditional feel.

Upgrade to GR4 if:

• You want maximum braking power for DH, freeride, or e-MTB.
• You prefer a firmer lever feel and instant engagement.
• You’re ready to switch to standard rotors and get the latest EVO performance.

Choose TR4 if:

• You ride trail or all-mountain terrain and value control.
• You want smoother modulation with near-V4 power.
• You appreciate the latest Hope design but don’t need vented rotors.

Whichever you choose, Gorilla Brakes provides the perfect replacement pads for all three — built to match or exceed OEM performance with advanced friction materials and consistent fade resistance.

6. Is Hope Discontinuing the V4?

Hope hasn’t formally announced a hard stop for V4 production, but retailers are already reporting limited stock. The company’s focus has clearly shifted to the EVO lineup, positioning GR4 and TR4 as the next generation of Hope’s four-piston brakes. For riders who love the V4, it’s still supported with spares and pad options through Gorilla Brakes — so there’s no rush to change unless you’re ready to upgrade.

7. Final Thoughts: The Gorilla Brakes Advantage

Whether you run the legendary V4 or the cutting-edge GR4/TR4, your brake pads are the heart of the system. Gorilla Brakes’ precision-engineered compounds are designed for modern MTB performance — delivering heat stability, bite control, and confidence under pressure.
