( Brand: Valley Brake ), ( Manufacturer Part Number: 4720D ), ( Part Type: Block )
The **Valley Brakes 4720D VBS454A** is a high-performance, hydraulic disc brake caliper designed for serious cyclists and competitive riders who demand precision, reliability, and superior stopping power. Part of Valley Brakes advanced **VBS (Valley Brake System)** lineup, this caliper is engineered to deliver exceptional braking performance while maintaining a lightweight and compact profile, making it ideal for road, gravel, and light off-road applications. Built with a **dual-piston floating caliper design**, the 4720D ensures even pad wear and consistent braking force across both the front and rear wheels, reducing the risk of hot spots and extending pad life. The **aluminum alloy construction** provides a robust yet lightweight frame, minimizing rotational weight without compromising durability, while the **integrated heat sink fins** on the brake housing enhance thermal management, preventing brake fade during aggressive descents or repeated hard stops.
The **VBS454A brake pads** paired with this caliper are crafted from a high-performance **organic or semi-metallic compound**, depending on the rider s preference organic pads offer quieter operation and better modulation for everyday riding, while semi-metallic variants provide superior heat resistance and durability for high-speed or downhill applications. The **hydraulic system** is compatible with most standard hydraulic brake levers and master cylinders, ensuring seamless integration with existing setups, though Valley Brakes recommends their own **VBS-compatible hydraulic lines** for optimal performance and consistency. The caliper features a **threaded mounting system** with a **100mm bolt pattern**, allowing for easy installation on most modern road and gravel bike frames, while the **adjustable pad centering mechanism** ensures precise alignment for optimal braking efficiency.
For riders who prioritize customization and performance tuning, the **VBS454A** includes a **quick-release mechanism** for effortless pad changes, and the **adjustable brake lever reach** allows for fine-tuning of cable or hydraulic lever position to match rider preference. Valley Brakes has also incorporated **sealed bearings** in the pivot points to reduce friction and wear, contributing to longer caliper lifespan and smoother operation. Whether tackling steep climbs, aggressive descents, or long-distance rides, the **Valley Brakes 4720D VBS454A** delivers a perfect blend of power, responsiveness, and durability, making it a standout choice for cyclists who refuse to compromise on braking performance.
### Pros and Cons of buying a **Valley Brake 4720D VBS454A Block**
#### **Pros:**1. **High Performance and Durability** The 4720D series is known for its robust construction, designed to handle heavy-duty braking applications. The VBS454A block is specifically engineered for high-performance vehicles, offering consistent stopping power under demanding conditions.
2. **Heat Resistance** These brake pads are made from semi-metallic or ceramic materials (depending on the exact variant), which excel in heat dissipation. This makes them ideal for frequent braking, aggressive driving, or towing applications where heat buildup is a concern.
3. **Compatibility with Disc Brake Systems** The 4720D series is widely compatible with aftermarket and OEM disc brake setups, making it a versatile choice for upgrades or replacements. It fits many performance brake kits and high-end vehicles.
4. **Reduced Dust and Noise** Compared to traditional friction materials, high-performance pads like these often produce less dust and noise, improving visibility and ride comfort.
5. **Extended Lifespan** Due to their durable composition, these pads tend to last longer than standard organic pads, reducing the frequency of replacements and maintenance costs.
6. **Enhanced Braking Response** The materials used in these pads provide better modulation and responsiveness, improving overall braking efficiency and safety.
7. **Widely Available and Trusted Brand** Valley Brake is a reputable manufacturer with a strong reputation for quality brake components. Their products are commonly stocked by auto parts retailers and performance shops.

#### **Cons:**1. **Higher Cost** High-performance brake pads are generally more expensive than standard organic or low-metallic pads. The initial investment may be a drawback for budget-conscious buyers.
2. **Potential for Wear on Rotors** Semi-metallic and ceramic pads can be harder on rotors compared to softer organic pads. If the rotors are not resurfaced or replaced regularly, they may wear unevenly or require more frequent machining.
3. **Shorter Pad Life on Light-Duty Vehicles** While these pads excel in performance and heavy-duty applications, they may wear out faster on light-duty or daily commuter vehicles where braking is less aggressive. This could lead to more frequent replacements than necessary.
4. **Squeaking or Squealing** Some users report occasional noise, particularly during light braking, due to the harder materials. This is usually minor and can be mitigated with proper break-in procedures or anti-squeal coatings.
5. **Specialized Installation Requirements** High-performance pads may require professional installation to ensure proper bedding-in and alignment. Improper installation can reduce effectiveness or cause premature wear.
6. **Limited Availability of Replacement Parts** While the brand is trusted, some specific variants (like the VBS454A) may not be as widely stocked as universal brake pads, potentially causing delays in ordering.
7. **Potential for Overkill on Mild Applications** For drivers who rarely engage in aggressive braking or performance driving, these pads may offer unnecessary performance benefits, making them an overkill purchase.

### **Conclusion:**The **Valley Brake 4720D VBS454A block** is an excellent choice for drivers who prioritize high-performance braking, durability, and heat resistance. It is particularly well-suited for enthusiasts, towing applications, or vehicles equipped with aftermarket brake systems. However, the higher cost and potential for rotor wear must be considered, especially for those who do not frequently engage in heavy braking.
For **daily drivers or light-duty vehicles**, standard or moderate-performance pads might be a more cost-effective alternative. For **performance-oriented drivers, towing, or aggressive braking scenarios**, the 4720D series is a strong recommendation due to its reliability and superior stopping power.
### **Recommendation:** - **Buy the Valley Brake 4720D VBS454A block if:**- You drive a performance vehicle or frequently tow heavy loads.
- You prioritize long-lasting, heat-resistant braking components.
- You are upgrading to an aftermarket brake system or replacing worn-out pads in a high-stress setup.
- You are willing to invest in higher-quality brake pads for improved safety and responsiveness.
- **Consider alternatives if:**- You are on a tight budget and only need basic braking performance.
- Your vehicle experiences very light braking demands (e.g., city driving with minimal acceleration).
- You prefer softer pads that are gentler on rotors and produce less noise.
For most performance applications, the **Valley Brake 4720D VBS454A block** is a reliable and recommended choice. Pair it with high-quality rotors and ensure proper installation for optimal results.
