### Pros and Cons of buying a Suzuki 69600-47011 (1977 1979 GS750 Rear Master Cylinder Reservoir Tank)

1. **Direct Fitment** This part is designed specifically for the 1977 1979 GS750, ensuring compatibility without modifications. It will slot into place without the need for adapters or customization, making installation easier for those with basic mechanical skills.

2. **Reliability** Suzuki parts, especially those from this era, are known for durability. The reservoir tank itself is a simple but critical component in the braking system, and a genuine or high-quality aftermarket part will perform reliably if properly maintained.

3. **Cost-Effective Replacement** Compared to rebuilding or replacing the entire rear master cylinder, this reservoir tank is a low-cost component. It s an easy fix for leaks, cracks, or wear that might otherwise require more extensive work.

4. **Easy to Source** While not as common as modern parts, this reservoir tank can be found through motorcycle parts dealers, online marketplaces (eBay, RockAuto, etc.), or specialty GS750 forums. Many sellers offer it as a standalone item, making it accessible without needing to purchase an entire brake assembly.

5. **Prevents Braking Issues** A failing reservoir tank can lead to air in the brake lines, spongy braking, or complete brake failure. Replacing it ensures the braking system operates as intended, improving safety.

6. **Minimal Downtime** Replacing the reservoir tank is a relatively quick job, often taking less than an hour for a DIYer. This means less time spent off the bike compared to more complex repairs.

---

1. **Age and Wear of Other Components** If you re buying this part to address a braking issue, the rest of the rear master cylinder or brake system may be degraded. The reservoir tank alone won t fix problems like worn seals, corroded lines, or a failing master cylinder. Inspecting or replacing these components may be necessary for a complete solution.

2. **Availability and Condition** Since this part is from an older model, finding a new or high-quality used example can be challenging. Some sellers may offer parts that have been stored improperly, leading to cracks, dry rot, or contamination. Always inspect the tank for leaks, brittleness, or signs of damage before purchasing.

3. **Compatibility with Aftermarket Mods** If your GS750 has been modified (e.g., with aftermarket brake systems, different brake lines, or a rebuilt master cylinder), the reservoir tank may not fit perfectly or may require additional work to integrate. Always verify compatibility with your specific setup.

4. **Potential for Counterfeit Parts** Older Suzuki parts, especially those sourced from overseas or third-party sellers, can sometimes be counterfeit or poorly made. Genuine OEM parts or reputable aftermarket brands (like Akebono, Brembo, or trusted GS750-specific suppliers) are safer bets.

5. **Limited Lifespan Expectation** Even if the tank is new, rubber and plastic components can degrade over time due to heat, brake fluid absorption, or environmental exposure. If your bike has high mileage or has been neglected, the tank may not last indefinitely and could need replacement again in the future.

6. **Skill Level Required** While the replacement is simple, working on the rear brake system of a GS750 may require some familiarity with motorcycle brakes. Improper bleeding of the brake lines or failure to purge air can result in spongy brakes or complete failure. Those without experience may need to consult a mechanic or detailed guides.

The Suzuki 69600-47011 rear master cylinder reservoir tank is a practical and cost-effective solution for addressing leaks, cracks, or wear in the braking system of a 1977 1979 GS750. It offers a direct fit, ease of installation, and improved braking reliability. However, it s important to recognize that this part alone may not solve all braking issues, and other components (like the master cylinder or brake lines) should be inspected for wear.

If you re confident in your mechanical abilities and can source a high-quality, undamaged part, replacing the reservoir tank is a wise investment. For those less experienced or dealing with broader brake system issues, consulting a mechanic or purchasing a complete rear master cylinder assembly might be more prudent.

---

1. **Verify the Condition of the Tank** If purchasing used, inspect the tank for cracks, dry rot, or leaks. A new or sealed OEM part is ideal.

2. **Check the Rest of the Brake System** While replacing the tank, examine the rear master cylinder, brake lines, and calipers for wear. Consider rebuilding or replacing the master cylinder if it s old or leaking.

3. **Use Proper Brake Fluid** Always use DOT 4 or DOT 5.1 brake fluid, and bleed the system thoroughly after installation to remove air.

4. **Consider a Rebuilt or Aftermarket Option** If the master cylinder is failing, a rebuilt unit (from a trusted supplier) may be more cost-effective than replacing individual components.

5. **Follow Installation Guidelines** Refer to a GS750 service manual or trusted online resources (like Haynes or GS750 forums) for step-by-step instructions to avoid common mistakes.

**Final Verdict:** If your primary issue is a leaking or damaged reservoir tank and you re comfortable with basic brake work, this part is a solid choice. For a more comprehensive fix, address the entire brake system to ensure long-term reliability.
