Overview

The HFM.Parts BM57 Big Bore Brake Master Cylinder is a performance upgrade designed for Right-Hand Drive (RHD) Nissan vehicles. It features a large 17/16" (27mm) piston bore to increase fluid displacement, resulting in a firmer pedal feel and shorter stopping distances.
Show original supplier description
Tired of spongy brakes? The HFM.Parts BM57 Big Bore Master Cylinder is engineered to replace and outperform the factory unit in your RHD Nissan Skyline, Silvia, or 300ZX. The primary upgrade is the massive 17/16″ (27mm) piston bore, which significantly increases fluid movement with less pedal input. This translates directly to a much firmer pedal feel and more confident, shorter stops, without needing to delete your brake booster. Constructed for longevity, the BM57 features a premium, environmentally resistant, chromium-free Black Geomet® coating, ensuring it looks clean in your engine bay and withstands corrosion. Technical specifications include a 17/16″ (27mm) piston bore, a split point of 35kgf (498psi) x 0.4, M10 x 1.0 outlet threads with a double flare (45-degree taper), and side-mounted ports compatible with banjo fittings. The fluid level sensor is also swappable to either side for installation flexibility. Installation requirements specify that if your vehicle is equipped with ABS brakes, you must block either the middle port or the rear port closest to the booster using the provided tapered grub screw. The product includes the BM57 Brake Master Cylinder and a tapered grub screw. HFM.Parts backs this master cylinder with a lifetime warranty against defects.
