#### **Cons:**1. **Cost** While not excessively expensive, a new or refurbished CL434654 caliper can range from $80 to $200, depending on the brand and condition. If you re on a tight budget, this may be a significant upfront cost, especially if you need to replace both front calipers or additional brake components (e.g., rotors, pads, or hoses).
2. **Potential Counterfeit Parts** Buying from untrusted sellers (e.g., eBay without seller verification or unknown online marketplaces) risks receiving counterfeit or low-quality parts. Counterfeit calipers may fail prematurely, leak, or not fit properly, compromising safety. Always purchase from verified sellers with return policies.
3. **Installation Challenges** While the replacement is manageable for DIYers, it requires careful attention to detail. Mistakes such as over-torquing bolts, not bleeding the brake system properly, or failing to lubricate the slide pins can lead to binding, leaks, or poor braking performance. If unsure, professional installation may be necessary.
4. **Compatibility with Aftermarket Mods** If your 4Runner has aftermarket modifications (e.g., lifted suspension, larger tires, or heavy-duty towing equipment), the stock CL434654 may not be sufficient for the increased load. In such cases, you might need a heavier-duty caliper (e.g., from Brembo or EBC) or a floating caliper kit to handle the extra heat and stress.
5. **Rust and Corrosion** If your 4Runner is driven in harsh conditions (e.g., salted roads, off-road mud, or coastal areas), the caliper may be prone to rust or corrosion over time. This can affect its longevity and require additional maintenance, such as regular cleaning and lubrication.
6. **Brake Fluid Maintenance** Brake calipers rely on hydraulic pressure, so the brake fluid must be fresh and free of moisture or contaminants. Neglecting brake fluid flushes (recommended every 2 years) can lead to corrosion inside the caliper, reduced braking efficiency, or even failure.
7. **Slide Pin Wear** Over time, the slide pins (which allow the caliper to move during braking) can wear out or seize, causing the caliper to drag or not retract properly. This can lead to uneven pad wear, overheating, and squeaking. Replacing the slide pins or the entire caliper may be necessary if this occurs.
8. **Limited Customization** The CL434654 is a stock or near-stock part, so it lacks the performance enhancements found in aftermarket calipers (e.g., larger bore pistons, improved cooling fins, or floating designs). If you re seeking aggressive braking upgrades, you may need to invest in a more advanced caliper.
9. **Time-Consuming Project** Replacing a caliper involves removing the wheel, rotor, and pads, bleeding the brake system, and ensuring everything is properly reassembled. This can take several hours, especially for a beginner, and may require multiple trips to the shop if tools or parts are missing.
10. **Environmental Factors** Extreme temperatures (e.g., very hot climates or frequent off-roading) can accelerate wear on the caliper. Heat can cause brake fluid to boil, leading to spongy brakes or failure. In such cases, you may need to upgrade to a more heat-resistant caliper or use higher-grade brake fluid (e.g., DOT 5.1).
