AP Racing AP5040 4 Piston Brake Kit | 330mm & 345mm Performance Discs
Introducing the AP Racing AP5040 4 piston brake kit designed for drivers seeking a high performance brake upgrade that delivers stronger stopping power, improved heat management, and refined brake modulation. This kit includes both 330mm and 345mm disc options to suit various wheel and driving requirements, making it ideal for performance cars, spirited driving, and occasional track use.
The 330mm and 345mm vented disc rotors provide increased friction surface and thermal capacity compared with standard rotors. The enhanced heat dissipation helps reduce brake fade during repeated braking, ensuring consistent performance even under high demand. Larger discs also improve leverage and friction engagement, contributing to shorter stopping distances.
Engineered with a 4 piston caliper design, this kit ensures even distribution of clamping force across the brake pad. This enhances friction efficiency and reduces uneven pad wear while delivering a smooth and predictable pedal feel. The AP5040 caliper design emphasizes balanced modulation and stable braking response for performance driving conditions.
The rotors are vented to promote airflow and heat dispersion, helping to maintain optimal brake temperatures and improve fade resistance. Combined with performance brake pads and braided brake lines, this brake kit creates a balanced system that enhances brake response, stability, and driver confidence.
Whether upgrading for daily road use, weekend spirited driving, or track days, the AP Racing AP5040 performance brake kit offers significant braking performance improvements over conventional systems. The combination of larger disc options and multi‑piston calipers delivers a reliable and consistent braking experience across a broad range of conditions.

Brake System Engineering Overview
Brake systems designed for enhanced performance must manage heat and hydraulic pressure effectively. Larger rotor sizes such as 330mm and 345mm increase the disc surface area and thermal mass, helping to absorb more heat and reduce brake fade during repeated braking.
Vented disc rotors promote efficient airflow to carry heat away from brake surfaces, maintaining consistent operating temperatures. Combined with balanced caliper clamping, this supports stable friction levels and better modulation.
Upgrading to performance brake pads and braided brake lines enhances the responsiveness of the braking system. High friction pad compounds maintain braking force at higher temperatures, and braided lines improve hydraulic feel for a firmer and more direct pedal response.
