Review WILWOOD
The Wilwood 831-15890 is a high-performance Brake Caliper Kit designed for front wheel applications. This kit includes everything needed for a big brake upgrade, including four (4) calipers, stainless steel brake lines, and mounting hardware.
The calipers in this kit are two-piece, forged aluminum monobloc design. Monobloc calipers integrate the piston, pad, and body into a single unit, resulting in increased rigidity and superior stopping power compared to traditional two-piece or floating calipers. The aluminum construction further reduces unsprung weight and aids in heat dissipation.
These calipers come with six (6) pistons each, providing ample braking force. The pistons use a custom-designed seal, ensuring a leak-free operation even under high-pressure and high-temperature conditions. The calipers use a dual-seal design, providing an extra layer of protection against brake fluid leaks.
The stainless steel brake lines, included in the kit, are direct replacement for the stock rubber lines. Stainless steel lines offer several advantages over rubber lines: they are resistant to swelling, corrosion, and degradation that can occur with harsh fluids or from prolonged exposure to sunlight. They also provide a firmer and more linear brake pedal feel compared to rubber lines.
This kit also comes with all necessary mounting hardware, including caliper brackets, caliper stabilizer brackets, and bolts. The hardware may be used to mount the calipers to the spindles, making installation a relatively straightforward process.
In summary, the Wilwood 831-15890 is a top-tier big brake kit that includes four calipers, stainless steel brake lines, and all necessary hardware for a front wheel application. The two-piece forged aluminum monobloc calipers offer superior stopping power, rigidity, and heat dissipation, while the stainless steel brake lines provide improved pedal feel and resistance to degradation.
Pros and Cons of Buying Wilwood 831-15890 Brake Kit
The Wilwood 831-15890 brake kit is a popular choice among car enthusiasts and racing communities for its high-performance capabilities. However, like any automotive part or accessory, there are advantages and disadvantages that come with purchasing this brake system. Striebig Therapy's impartial analysis will highlight these factors to help readers make an informed decision.
Pros:1. Superior Braking Performance: The primary advantage of Wilwood brake kits is their enhanced braking power. The 831-15890 kit includes 4-piston front calipers with 13-inch rotors and 2-piston rear calipers with 13-inch rotors, delivering better stopping power than OEM systems.
2. Lightweight Construction: Wilwood uses lightweight materials like billet aluminum and stainless steel for the caliper bodies and brake lines. This reduces unsprung weight, improving vehicle handling and response.
3. Greater Heat Dissipation: The larger, thinner rotors in this kit provide excellent heat dissipation, reducing the risk of brake fade during prolonged, high-performance driving.
4. Customizability: Users can choose various caliper finishes, rotor sizes, and pad compounds based on their specific driving needs and preferences.
5. Upgraded Pedal Feel: The Wilwood brake kit provides a firmer, more responsive pedal feel, giving drivers a greater sense of control over their vehicle.
Cons:1. Cost: Wilwood brake kits can be expensive when compared to OEM options. The superior materials and high-performance capabilities justify the price increase for many buyers. However, those on a tight budget might be deterred.
2. Installation Complexity: Installing a Wilwood brake kit may require professional assistance or extensive automotive knowledge due to the various components and configuration adjustments needed during the installation process.
3. Pedal Box Modifications: Depending on the specific vehicle application, some Wilwood brake kit installations may require modifications to the pedal box to accommodate the larger caliper profile.
4. Brake Line Upgrades: Wilwood recommends using their aftermarket brake lines with their brake systems. This adds an additional cost to the overall purchase price.
Conclusion:The Wilwood 831-15890 brake kit offers significant advantages for drivers seeking superior braking performance, lightweight components, and customizability. It's particularly beneficial for those who engage in high-performance driving or motorsports applications. However, the higher cost, complex installation process, pedal box modifications, and necessitated brake line upgrades may deter some buyers. Consider your driving needs, budget, and automotive expertise before making a purchase decision on this high-performance brake kit.
Recommendation:If you require outstanding braking performance for your high-performance vehicle or racing application, the Wilwood 831-15890 brake kit is an excellent choice. Alternatively, if you prioritize affordability, ease of installation, or simpler maintenance, you may want to explore alternative brake system options.
