Review HONDA Front Brake Master Cylinder fits SHADOW 1100 1300 VTX1300 VT1100 VT VTX 1999–2007

The **Honda 45500-MK7-671 Front Brake Master Cylinder** is a precision-engineered component designed exclusively for the **1999 2007 Honda VT1100 Shadow Spirit** and **VTX1300 Shadow VTR**, ensuring optimal braking performance and reliability for these iconic cruising motorcycles. Part of Honda s high-quality aftermarket replacement line, this master cylinder is meticulously crafted to meet or exceed OEM specifications, guaranteeing seamless integration with the bike s hydraulic braking system. Built with a durable **aluminum alloy body**, it combines lightweight construction with structural integrity, reducing unsightly weight while maintaining robustness under demanding riding conditions. The cylinder features a **dual-piston design**, delivering consistent brake fluid pressure and precise modulation for both the front disc brake and, in the case of the VTX1300, the optional rear brake system, ensuring responsive stopping power whether cruising on open highways or navigating tight city streets. Its **sealed, corrosion-resistant construction** protects against environmental elements, including moisture and road debris, which can compromise performance over time. The master cylinder is compatible with **DOT 4 or DOT 5.1 brake fluid**, allowing riders to choose the most suitable fluid for their climate and riding habits, while the integrated **bleeding port** simplifies maintenance, enabling easy removal of air bubbles for optimal hydraulic efficiency. Whether restoring a classic VT1100 or upgrading a VTX1300, this master cylinder is a critical component for maintaining safety, control, and confidence in every ride. Built to Honda s exacting standards, it embodies the brand s reputation for durability and performance, ensuring that your motorcycle s braking system operates with the same reliability as the day it left the factory.

### **Pros and Cons of Buying a 1999 Honda VT1100/VTX1300 (Shadow VTX1300/VT1100, 45500-MK7-671, Front Brake Master Cylinder Issue)**

#### **Pros**

1. **Classic Reliability** Honda s VT1000/1100/1300 series is well-known for durability, especially the air/oil-cooled engines. The 1100cc and 1300cc models are robust and can last well over 100,000 miles with proper maintenance.

2. **Proven Engine** The VT1100 and VTX1300 use a liquid-cooled, parallel-twin engine with a reputation for longevity. The VT1300, in particular, is a more refined version with better power delivery and smoother operation.

3. **Comfortable Ride** Both models feature a comfortable ergonomic design, long-travel suspension, and a relaxed riding position, making them ideal for touring and long-distance rides.

4. **Good Fuel Economy** For a cruiser-style bike, the VT1100/VTX1300 offers decent fuel efficiency, averaging around **40-50 mpg** (varies with riding style and conditions).

5. **Aftermarket Support** There is a strong aftermarket presence for these bikes, with available parts for upgrades (exhaust, suspension, handlebars) and customization options.

6. **Resale Value** Honda s cruisers hold their value better than many competitors, especially well-maintained examples.

7. **Low Maintenance Costs** Compared to modern bikes, parts and labor are relatively affordable, and the engine is simple enough for DIY maintenance.

8. **Touring Capability** The VTX1300, in particular, is designed with touring in mind, featuring a comfortable seat, windshield mounts, and a sturdy frame.

9. **Classic Aesthetics** The Shadow VTX1300 has a timeless, retro look that appeals to riders who prefer a classic cruiser style without the bulk of modern touring bikes.

10. **Proven Brake System (When Fixed)** While the front brake master cylinder issue is a concern, Honda s disc brake system (especially on the VTX1300) is generally reliable once properly addressed.

---

#### **Cons**

1. **Front Brake Master Cylinder Issue** The most significant drawback is the reported failure of the front brake master cylinder. This can lead to **spongy or completely lost front braking**, which is dangerous. The bike may require a **replacement master cylinder** or a **brake bleed** to restore proper function. This is a **critical safety concern** that must be addressed before purchasing.

2. **Age and Wear** Being from **1999**, the bike has been on the road for over **25 years**, meaning potential wear in the **chain, sprockets, tires, suspension, and electrical components**. A thorough inspection is essential.

3. **Potential Rust Issues** If stored in a wet climate, the frame, swingarm, or suspension may have rust. A **pre-purchase inspection** is highly recommended.

4. **Electrical Reliability** Older Hondas can develop **electrical gremlins**, such as faulty switches, dim headlights, or intermittent instrumentation. Testing all electrical components is crucial.

5. **Limited Modern Tech** Unlike newer bikes, this model lacks **trail cam, ABS, or advanced fuel injection tuning**, which may be a dealbreaker for some riders.

6. **Weight** The VTX1300 is heavier than modern sport or adventure bikes, which can make maneuvering in tight spaces slightly more difficult.

7. **Fuel Injection Sensitivity** The **PGM-FI system** can be finicky with fuel quality. Using **high-quality fuel** is necessary to avoid clogging or performance issues.

8. **Limited Stocking of Original Parts** While aftermarket parts exist, some original Honda components may be harder to find, increasing repair costs over time.

9. **Comfort Trade-offs** While the ergonomics are good, the **upright riding position** may not suit riders who prefer a more aggressive or sporty stance.

10. **Potential Hidden Damage** Without a **professional inspection**, issues like **frame cracks, bent forks, or internal engine wear** could go unnoticed.

### **Ending Conclusion**

The **1999 Honda VT1100/VTX1300 Shadow** is a **solid, reliable cruiser** with a strong reputation for durability, comfort, and fuel efficiency. However, the **front brake master cylinder issue** is a **major red flag** that must be resolved before purchasing. If the bike has already had this problem fixed (with a **new master cylinder and proper brake bleeding**), it could be a **great value** for a rider who appreciates classic Honda engineering.

- Values **classic cruiser aesthetics and comfort**

- Is prepared for **potential maintenance costs**

- Will **thoroughly inspect or have a mechanic check** the bike

- Doesn t mind **older technology** in exchange for reliability

this bike could be an **excellent purchase**.

**For others**, especially those who prioritize **modern safety features (ABS, better brakes, electronics)**, a **newer Honda (e.g., Gold Wing, NT1100, or even a used modern cruiser)** might be a better choice.

---

### **Recommendation**

- **Demand a pre-purchase inspection** (PPI) from a **Honda specialist** or a trusted mechanic.

- **Verify the front brake master cylinder** has been replaced and the brakes have been **bled properly**.

- **Check for rust, chain wear, tire condition, and electrical functionality**.

- **Test ride the bike** to ensure smooth shifting, no unusual noises, and proper braking.

- **Proceed with purchase** if the bike is otherwise in good condition.

- **Budget for potential maintenance** (chain, sprockets, suspension, tires).

- **Consider upgrading the exhaust** for better sound and performance.

- **Negotiate a lower price** or **walk away** this is a **safety risk** that shouldn t be ignored.

- If you like the VTX1300 s style but want **better brakes**, consider a **used 2000s Honda Gold Wing (GL1800)** or **NT1100**.

- For a **more modern cruiser**, a **used Harley-Davidson (e.g., Softail or Tour Glide)** or **Indian Scout** could be worth exploring.

This bike **has potential** if the **brake issue is properly addressed** and the rest of the bike is mechanically sound. However, **buyers must approach it with caution**, prioritizing safety and thorough inspection. For the right rider, it s a **great classic cruiser**; for others, a **newer model with modern safety features** may be preferable.
