The master cylinder piston consists of a dual structure which uses pistons with 2 different diameters. The large diameter piston is used for normal braking to achieve a rigid braking feeling using short strokes. If a malfunction occurs in the brake booster with accumulator pump assembly, brake depression force activates the small diameter piston to ensure braking force for the front brake.
