  • Proportioning Valve Adjustment

    The proportioning valve, a often overlooked element, plays a crucial role in regulating hydraulic pressure between the front and rear brakes. In an unmodified IS300, this valve is calibrated for the factory braking system. When an “is300 big brake kit” is installed, the increased braking capacity of the front calipers can upset this balance, leading to premature rear wheel lockup or, conversely, underutilization of the rear brakes. Adjusting or replacing the proportioning valve becomes a necessity, tailoring the pressure distribution to the new braking system. Consider a scenario: an IS300 equipped with an aggressive front braking setup approaching a corner on a track. Without proper proportioning valve adjustment, the rear wheels could lock under heavy braking, inducing instability and compromising control. Fine-tuning this valve ensures that the rear brakes contribute their fair share of stopping power without exceeding their capacity.

  • Caliper and Rotor Sizing

    The size of the calipers and rotors selected for the “is300 big brake kit” directly impacts the overall brake balance. Simply installing the largest possible components on the front axle can lead to a front-biased braking system, which, while providing impressive initial bite, can compromise stability during hard braking. Careful consideration must be given to the relative sizes of the front and rear components, ensuring that the braking force is distributed in a manner that complements the vehicle’s weight distribution and suspension characteristics. The goal is to create a system where all four wheels contribute equally to the deceleration process, maximizing stopping power while minimizing the risk of wheel lockup. Achieving this balance requires a deep understanding of braking system dynamics and a meticulous approach to component selection.
