Review YAMAHA Rear Drum Brake fits IT175 1977

The **Yamaha 1977 IT175 Rear Drum Brake (Part #2205603)** is a meticulously engineered component designed to deliver reliable stopping power for classic Yamaha motorcycles, particularly those from the late 1970s and early 1980s. This rear drum brake assembly represents a blend of durability and precision engineering, tailored to the performance demands of the IT175, a lightweight, fuel-injected sport-touring bike known for its agile handling and refined ride. Crafted from high-quality materials, the brake features a robust cast-iron drum housing, which is both sturdy and resistant to wear, ensuring long-lasting performance even under demanding conditions. The internal mechanism includes a finely balanced shoe assembly, complete with self-adjusting hardware that maintains optimal clearance between the brake shoes and the drum, reducing the need for frequent manual adjustments. This self-adjusting feature not only enhances convenience for riders but also contributes to consistent braking efficiency, reducing the risk of brake fade or uneven wear over time. The brake s design incorporates a reliable spring system that applies even pressure across the shoes, ensuring a smooth and progressive stopping response, which is particularly valuable for riders seeking a balance between control and comfort. Whether you're restoring a vintage IT175 to its original glory or maintaining one for daily riding, this rear drum brake is a critical component that upholds the bike s classic charm while delivering the performance expected of a Yamaha. Its compatibility with the IT175 s drivetrain ensures seamless integration, allowing enthusiasts to enjoy the thrill of riding a piece of motorcycle history with confidence in their braking system s reliability.

The Yamaha IT175 from 1977 is a classic 175cc motorcycle, and the rear drum brake (part number 2205603) is a key component for maintaining its performance and safety. Below are the pros and cons of purchasing this specific brake, followed by a conclusion and recommendation.

### Pros of buying a Yamaha 2205603 Rear Drum Brake

1. **Authenticity and Originality** If you own a vintage Yamaha IT175 and want to restore it to factory specifications, this OEM brake ensures an exact fit and proper functionality. Original parts preserve the bike s historical integrity and resale value for collectors.

2. **Reliability of Drum Brakes** Drum brakes, while less efficient than modern disc brakes, are durable and robust. They are less prone to warping or thermal fade compared to some disc brake setups, making them a dependable choice for a classic bike that may not see heavy daily use.

3. **Ease of Installation** Drum brakes are relatively straightforward to install, especially for someone with basic mechanical skills. The IT175 s design is simple, and the brake system is less complex than modern systems, reducing the risk of installation errors.

4. **Availability of Replacement Parts** While not as widely available as modern parts, drum brake components for classic Yamaha motorcycles are still accessible through specialty vendors, eBay, or restoration shops. This makes it easier to source additional parts if needed.

5. **Cost-Effectiveness** Compared to aftermarket or modern upgrades, OEM drum brakes are often more affordable. This can be beneficial for budget-conscious restorers or those who prioritize authenticity over performance gains.

6. **Compatibility with Classic Maintenance** The IT175 s drum brake system aligns with traditional maintenance practices, such as adjusting shoe clearance and lubricating pivot points. This can be appealing to enthusiasts who enjoy hands-on restoration work.

### Cons of buying a Yamaha 2205603 Rear Drum Brake

1. **Poor Stopping Performance** Drum brakes are significantly less effective than modern disc brakes, especially in wet or high-speed conditions. The IT175 s rear drum brake may struggle to provide adequate stopping power, which could be a safety concern if the bike is ridden aggressively or in modern traffic.

2. **Maintenance Requirements** Drum brakes require regular adjustments to shoe clearance and lining wear. Over time, the brake shoes can wear unevenly, leading to reduced effectiveness or even failure if not maintained properly. This adds to the upkeep of the bike.

3. **Limited Modern Upgrade Options** If you eventually decide to upgrade to disc brakes (which is common for classic bikes), the drum brake system may become obsolete. Installing a modern rear disc brake kit would require significant modifications, including wheel changes and suspension adjustments.

4. **Potential for Rust or Wear** Older drum brakes, especially those from the 1970s, may have rusted components or worn-out parts (e.g., springs, shoes, or backing plates). Even if the brake itself is functional, associated hardware (like the brake lever or cable) might need replacement.

5. **Difficulty Finding Specialists** While drum brakes are simple, finding a mechanic experienced with vintage Yamaha drum brake systems can be challenging. Most modern shops may not have the expertise or tools to service them efficiently.

6. **Environmental and Safety Concerns** Drum brakes generate more heat and dust than disc brakes, which can be less desirable for daily riding. Additionally, the lack of modern braking technology may not meet contemporary safety standards, particularly for riders who plan to use the bike on modern roads.

### Conclusion

The Yamaha 2205603 rear drum brake is a practical choice if you are restoring an IT175 to its original condition and prioritize authenticity over performance. It is a reliable, durable option for a classic bike that will likely see limited or occasional use, particularly by collectors or enthusiasts who appreciate the historical aspect of the motorcycle. However, if you plan to ride the bike frequently or in modern conditions, the lack of stopping power and maintenance demands may outweigh the benefits.

For riders who want a balance between authenticity and safety, considering a modern rear disc brake upgrade (such as a GTS or aftermarket kit) could be a better long-term investment, even if it means deviating from the original specification. The decision ultimately depends on your priorities: whether you value historical accuracy, ease of maintenance, or modern safety and performance.

### Recommendation

If you are restoring the IT175 for display or as a project bike with minimal riding, purchasing the OEM drum brake is a sound choice. Ensure you also inspect the associated components (brake shoes, springs, and cable) for wear or rust, and replace them if necessary. Pair this with regular maintenance to keep the brake system functional.

If you plan to ride the bike regularly or in modern conditions, consider investing in a rear disc brake conversion. While this requires more effort and cost upfront, it will significantly improve safety and handling. Many aftermarket kits are available for the IT175, and the performance gains especially in stopping power and modulation will be noticeable.

For most modern riders, the trade-offs of a drum brake are not worth the compromise in safety and reliability. However, for purists or those restoring a bike for static display, the OEM drum brake remains a fitting choice.
