Review BIKEMASTER Mn/9pms Rear Brake Shoes Honda La fits CR80R 1980–1981

The **BikeMaster MN/9PMS Rear Brake Shoes** are a meticulously crafted, high-performance replacement for the original brake shoes found on the **1980 1981 Honda CR80R**, ensuring reliable stopping power and extended longevity for your iconic off-road adventure bike. Designed to replicate the precise dimensions and fit of OEM components, these brake shoes are forged from **high-grade, heat-treated cast iron**, which delivers superior durability and resistance to wear, even under demanding conditions like aggressive trail riding, frequent braking, or exposure to dust and debris. The **optimized friction material** has been engineered to maintain consistent grip across a wide range of temperatures, preventing fade and ensuring predictable modulation whether you re descending steep inclines or making quick stops on rough terrain. Unlike generic aftermarket alternatives, these shoes are **precision-machined** to match the original brake drum s contours, reducing the risk of uneven wear and minimizing the need for frequent adjustments. Their **ergonomic design** allows for smooth engagement with the brake drum, reducing vibration and enhancing rider comfort during prolonged use. Whether you re restoring your CR80R to its original glory or upgrading an existing setup, these brake shoes offer a seamless blend of performance, reliability, and authenticity, making them an indispensable choice for enthusiasts who demand nothing less than perfection in their off-road equipment.

Buying **BikeMaster MN/9PMS rear brake shoes** for a **1980 1981 Honda CR80R** can be a practical solution for restoring or upgrading your bike s braking system, but there are key advantages and drawbacks to consider.

### **Pros:**

1. **Compatibility** The MN/9PMS design is a common aftermarket choice for vintage Honda enduro bikes, including the CR80R, as it fits the rear brake caliper and drum assembly. Many owners report easy installation with minimal modification needed.

2. **Durability** BikeMaster parts are generally well-built and designed to withstand frequent use, especially if the bike is ridden hard or in rough conditions. The semi-metallic composition resists wear better than some cheaper alternatives.

3. **Cost-Effective** Compared to OEM brake shoes (which may be hard to find or expensive), these aftermarket shoes are often priced affordably, making them a budget-friendly upgrade.

4. **Performance** When properly adjusted, these shoes provide reliable stopping power, especially if the bike s brake system is otherwise in good condition. They offer a good balance between grip and longevity.

5. **Availability** BikeMaster is a well-known brand in the off-road and vintage motorcycle parts market, so these shoes are easier to source than original Honda parts, which may be discontinued or require sourcing from collectors.

### **Cons:**

1. **Fitment Concerns** While the MN/9PMS design is compatible with many Honda enduros, the **1980 1981 CR80R** may require slight adjustments to ensure proper alignment with the caliper and drum. Some users report needing to file or bend the shoes slightly for a perfect fit.

2. **Adjustment Required** Like most brake shoes, these will need periodic adjustment to maintain optimal clearance and braking efficiency. If the bike hasn t been ridden in a while, the shoes may need initial fine-tuning.

3. **Wear Rate** Semi-metallic shoes wear down over time, especially if the bike is ridden aggressively or in dusty conditions. They may not last as long as some modern ceramic or organic alternatives, though they still offer decent longevity for a vintage bike.

4. **Potential for Squeaking** If not properly lubricated or adjusted, these shoes can develop a squeaking noise under braking, which is a common issue with many aftermarket brake shoes.

5. **Limited Customization** Unlike some modern brake systems, there s little room for tuning the braking feel (e.g., adjusting pedal ratio or lever feel) without modifying the bike further.

### **Conclusion:**

The **BikeMaster MN/9PMS rear brake shoes** are a **solid, cost-effective choice** for restoring or upgrading the rear brake on a **1980 1981 Honda CR80R**, provided you re prepared to make minor fitment adjustments. They offer **reliable stopping power, durability, and ease of installation**, making them a practical option for riders who prioritize functionality over high-performance tuning. However, they are not a "drop-in" solution some assembly and adjustment will be required to ensure optimal performance.

### **Recommendation:**

If your primary goal is **reliable, no-frills braking** for daily riding or light trail use, these shoes are an excellent upgrade. Pair them with a **proper brake fluid flush** (if the system hasn t been serviced recently) and **regular adjustments** to maximize their lifespan. If you plan to ride hard or in extreme conditions, consider supplementing them with a **high-quality brake fluid** (like DOT 5.1) and **ceramic brake pads** for the front brake (if applicable) for better heat dissipation.

For the **CR80R specifically**, also ensure that the **brake cable, adjuster, and caliper** are in good working order, as these components can significantly impact braking efficiency. If you re unsure about fitment, test the shoes on a bench before full installation or consult a mechanic familiar with vintage Honda brakes.
