Enhanced Stopping Power and Performance Characteristics of the Wilwood 140-11743 Brake Kit
The performance characteristics of the Wilwood 140-11743 Dynapro Radial 11.75" Front Hub Big Brake Kit are a key selling point for enthusiasts looking to upgrade their braking system. This section delves into the specific features that enhance stopping power and overall performance, making it a top choice for the 1964-1967 Sunbeam Tiger.
At the heart of the Wilwood 140-11743 kit is the advanced caliper design. The calipers utilize a four-piston configuration that allows for greater clamping force and improved modulation. This design means that when you apply the brakes, the force is distributed evenly across the rotor, reducing the likelihood of uneven wear and increasing the lifespan of both the pads and rotors. The kit comes with high-friction brake pads that are specifically formulated to provide optimal performance in both street and track conditions.
The inclusion of 11.75" rotors is another significant advantage. These rotors are not only larger than stock options, but they also feature a slotted design that helps to dissipate heat and improve performance under heavy braking. The slots allow for better gas and dust venting, which keeps the surface of the rotor clean and enhances the pad-to-rotor contact. This results in shorter stopping distances and improved safety, especially in high-speed scenarios.
Moreover, the Wilwood 140-11743 kit is designed with an emphasis on heat management. The rotors are made from a high-carbon cast iron material, which is known for its durability and ability to withstand extreme temperatures. During extensive testing, the rotors showed minimal signs of warping or cracking, even after repeated hard stops, which is a testament to their engineering and material quality.
Another feature that enhances the performance of the Wilwood 140-11743 kit is the inclusion of stainless steel brake lines. These lines not only resist expansion under pressure but also provide a firmer pedal feel, which is crucial for precise braking control. The kit’s design ensures that the brake lines are routed in a way that minimizes the risk of damage and maximizes reliability.
