#### **Cons:**1. **Potential for Inconsistent Quality** While Unlimited is a well-regarded brand, **quality can vary by batch**. Some users report **uneven wear or premature failure** if the kit is not installed correctly or if the vehicle s brake system is neglected.
2. **Not a Full Brake Upgrade** This is **only a brake shoe kit**, meaning it does not include **rotors, pads, or other components**. If your rotors are worn or warped, you ll need to replace them separately, adding to the cost.
3. **Noise Concerns** Some aftermarket brake shoes, especially high-friction types, can generate **more noise (squeaking, grinding)** than OEM parts. This may require **adjustment or the use of anti-squeal compounds** during installation.
4. **Limited Warranty** Unlike OEM parts, which often come with **extended warranties**, aftermarket brake kits typically have **shorter warranties (often 1 year or less)**. If the shoes fail prematurely, you may be responsible for replacement costs.
5. **Potential for Overheating** High-friction brake shoes can **generate more heat**, which may not be ideal for **lightweight or high-performance vehicles** where excessive heat can warp rotors or damage other components.
6. **Installation Risks** If not installed correctly, **uneven brake shoe contact** can lead to **poor braking performance, excessive wear, or even brake failure**. Improper installation may also void warranties.
7. **Compatibility Issues with Some Mods** If your vehicle has been **modified with larger rotors, calipers, or performance brake systems**, this kit **may not fit properly** and could require additional adjustments.
