Show original supplier description
The kit's extreme lightweight, one-piece caliper is CNC machined from aircraft-quality billet, featuring a differential bore and weighing just over five pounds. It incorporates aluminum pistons, high-temperature seals, and stainless-steel brake pad wear plates, along with machined protection grooves for the bridge tubes. This opposed piston caliper design significantly enhances pad wear and caliper rigidity compared to OEM systems. The kit utilizes stainless-steel brake lines that resist expansion under pressure, ensuring consistent braking performance. Ksport employs a two-piece disc assembly to minimize both rotating and unsprung weight. Many applications offer a floating disc option to prevent thermal stresses and warping under extreme heat. The unique rotor slot design aids in reducing braking noise and expelling gas and pad debris more efficiently. Rotors are heat-treated and balanced for optimal performance. Cross-drilled rotors are recommended for daily-driven vehicles for cooler operation, while slotted rotors are better suited for track use. This specific kit, model BKLX030-443CO, is designed for the Lexus ES300 from 1992-1996. It is stated that Ksport Big Brake kits generally fit 2WD vehicles unless otherwise specified. It is important to note that all products sold by Ksport USA are designated for Off-Road Use Only unless explicitly stated otherwise, intended for competition or racing sanctioned by a recognized organization.
