Tired of Spongy Brakes? Upgrade to the HFM BM57 Big Bore Master Cylinder.
Excessive brake pedal travel and a mushy, unresponsive feel erode confidence on the street and cost you crucial stopping distance on the track. The HFM.Parts BM57 is the definitive performance upgrade for your left-hand drive (LHD) Nissan chassis, engineered to replace and outperform the factory master cylinder.
The key to this upgrade is the Massive 17/16″ (27mm) Piston Bore. By dramatically increasing the piston size, the BM57 moves more fluid with less pedal input, instantly translating to a firmer pedal feel and shorter, more confident stops. It’s the simplest way to transform your braking response without deleting your brake booster.
Pro Tip: Soften your pedal feel by increasing the brake booster size. It pairs perfectly with our BM57 for customised braking.

Our Story
We weren't always HFM.Parts; we were Holford Motors. Our brand's identity was forged not in an office, but on the local circuits in the high-stress world of competitive drifting. Our ultimate testbed was our Nissan S14 Drift car, driven by champion Luke Fink. Pushing that car to its limits exposed a crucial truth: achieving genuine, repeatable performance meant relying on components that simply weren't available affordably on the market.
The HFM.Parts brand was born
We made the commitment to design and manufacture the uncompromising, high-quality performance parts that we, as competitive racers, demanded ourselves. Every component you see is a solution conceived, tested, and proven by us. When you choose HFM.Parts, you are investing in components engineered by racers, for racers, ensuring your vehicle delivers its maximum performance potential.
Modifying vehicles is a specialist task and requires the knowledge and experience of competent
individuals to
