**Pros and Cons of Buying Bikemaster MN/NNG9 Rear Brake Shoes for a 1973 1977 Suzuki GT750 Le Mans/FJ**

### **Pros**

1. **Compatibility** The Bikemaster MN/NNG9 brake shoes are designed specifically for the Suzuki GT750 s rear brake system, ensuring a proper fit without modification. The Le Mans and FJ models share the same rear brake caliper and drum, so these shoes will work seamlessly.

2. **Performance** These shoes are made from high-quality semi-metallic or organic friction material, which provides better braking performance than OEM parts. They offer improved modulation, reduced fade, and more consistent stopping power, especially under hard use or in wet conditions.

3. **Durability** Bikemaster is a reputable brand known for producing long-lasting brake components. The NNG9 shoes, in particular, are often praised for their longevity compared to aftermarket alternatives or original equipment.

4. **Ease of Installation** Since they are direct replacements, installation is straightforward. No resizing or special tools are required beyond basic brake service procedures (cleaning the drum, adjusting the shoes, and setting the springs).

5. **Cost-Effective Upgrade** While not the cheapest option, they offer a significant improvement over OEM shoes at a reasonable price. They strike a balance between performance and affordability compared to high-end aftermarket brands.

6. **Widely Available** These shoes are stocked by many motorcycle parts retailers, both online and offline, making them easy to source without long waits or special ordering.

7. **Compatibility with Other Mods** If you ve already upgraded other components (e.g., rear disc conversion kits, larger calipers, or performance springs), these shoes will integrate well without causing conflicts.

### **Cons**

1. **Limited Customization** Unlike some aftermarket shoes designed for aggressive riding (e.g., track use), the NNG9 shoes are tuned for street and light sport riding. If you plan to push the bike hard on the track or in aggressive stop-and-go conditions, you may eventually need a more aggressive compound.

2. **Potential for Dust and Wear** Semi-metallic shoes can generate more dust than organic alternatives, which may require more frequent cleaning of the drum and caliper. Over time, this dust can accumulate and affect braking efficiency if not maintained.

3. **Adjustment Required** After installation, you ll need to properly adjust the shoes to ensure even contact with the drum. Improper adjustment can lead to uneven wear, reduced braking, or even binding. This requires some mechanical skill or patience.

4. **Price Relative to OEM** While still reasonable, these shoes cost more than OEM replacements. If you re on a tight budget and only need a basic upgrade, you might consider other aftermarket options that are slightly cheaper.

5. **Availability of Alternatives** There are other aftermarket brands (e.g., EBC, Akebono, or local manufacturers) that offer similar or slightly different compounds. Some riders prefer these alternatives for specific reasons (e.g., quieter operation, different fade characteristics).

6. **Potential for Overheating** If the bike is ridden aggressively (e.g., frequent hard stops, track use), the shoes may overheat, leading to reduced effectiveness or premature wear. This is more of a risk with any brake upgrade but is worth considering if you plan to push the bike hard.

7. **Drum Condition Dependency** For optimal performance, the rear drum must be in good condition. If the drum is warped, scored, or excessively worn, the new shoes may not perform as intended, and the drum may need resurfacing or replacement alongside the shoes.

### **Conclusion and Recommendation**

The **Bikemaster MN/NNG9 rear brake shoes** are an excellent choice for upgrading the rear brakes on your 1973 1977 Suzuki GT750 Le Mans or FJ. They offer a **direct, high-quality replacement** that improves braking performance, durability, and reliability without requiring major modifications. The shoes are well-suited for street riding, light sport use, and even occasional aggressive stops, making them a versatile upgrade.

If your primary goal is to **enhance braking performance, extend the life of your rear brake system, and avoid the hassle of frequent OEM replacements**, the Bikemaster NNG9 shoes are a **strong and reliable choice**. Pair them with a **clean rear drum**, proper adjustment, and regular maintenance (cleaning and inspection) to maximize their lifespan and effectiveness.

For riders who plan to **push the bike harder** (e.g., track days, aggressive stop-and-go), consider supplementing these shoes with a **rear disc conversion kit** (if you haven t already) or exploring **more aggressive aftermarket shoes** (e.g., EBC 3C or Akebono 1000s) for better heat resistance. However, for most street and light sport applications, the NNG9 shoes will deliver **noticeable improvements** over OEM parts.

**Final Verdict:** **Buy them.** They are a practical, well-supported upgrade that will pay for themselves in better braking and longevity.
