Overview

This kit integrates new brake technology to reduce brake fade and cool brake pads during use. It features a lightweight, aircraft-quality billet caliper with aluminum pistons, high-temperature seals, and stainless steel wear plates, all within a differential bore configuration. The opposed piston design improves pad wear and caliper rigidity, while stainless steel brake lines prevent expansion under pressure.

Show original supplier description

This rear brake upgrade features a sophisticated 4-piston ProComp caliper, machined from aircraft-quality billet, designed for optimal rigidity and pad wear. The caliper boasts aluminum pistons, high-temperature seals, and stainless steel brake pad wear plates, complemented by stainless steel brake lines that resist expansion under pressure. The kit utilizes a 2-piece floating disc assembly to reduce unsprung and rotating weight. The floating design mitigates thermal stress, preventing rotor warping and cupping. The unique rotor slot design helps expel gas and pad debris efficiently, reducing braking noise. This specific kit features 330mm (13-inch) slotted rotors, recommended for vehicles that see more track use than daily driving, though cross-drilled rotors are an option for cooler operation on daily drivers. It is specifically designed for the 1991-1994 Nissan Sentra B13 chassis, equipped with the 2.0L 1998CC 122Cu. In. l4 GAS DOHC Naturally Aspirated engine. Please note that this specific kit is for the rear application and the "OEM Handbrake Will Not Function" as indicated by the part number.
