3540100-GC010 Brake Master Cylinder

Toyota's 3540100-GC010 Brake Master Cylinder is a core brake component developed based on international standardized technology. It is designed for commercial vehicles and hybrid platforms. Its core function is to convert the driver's pedal force into balanced hydraulic output, and achieve precise distribution of front and rear wheel braking force through a dual-chamber series structure. The component adopts a high-strength aluminum alloy casting process (in accordance with T/ZZB 2389-2021 standards), the master cylinder diameter is 28.58mm, and can withstand 32MPa hydraulic pressure.

The 3540100-GC010 Brake Master Cylinder adopts a dual-piston compensation valve structure and is equipped with fast filling valve technology to ensure hydraulic stability under extreme braking conditions. Its sealing system is made of high-temperature resistant fluororubber (in accordance with HG2865-1997 standard), with an operating temperature range of -40℃ to 180℃, and the piston return time is strictly controlled within 1.5 seconds (meeting the technical requirements of QC/T 311-1999). Test data shows that after 15 consecutive emergency brakes from 100-0km/h, the hydraulic fluctuation amplitude is less than 0.3MPa, and the friction coefficient is stable in the range of 0.38-0.42, effectively suppressing the thermal decay phenomenon.

The threaded interface of this model of master cylinder adopts a front port 1/2"-20 inverted design, which perfectly matches the brake line layout of Toyota commercial vehicles and avoids the risk of leakage caused by tolerance. Its OE number is fully compatible with derivative models such as 3540100-GC011 and 3540100-GC015, and has passed TS16949 certification, supporting the coordinated operation with third-party replacement parts such as TRW BWN153 and AISIN MCT-033.
