The brake master cylinder is the core component of an automotive braking system, primarily consisting of a seal ring (ensuring sealing integrity), cylinder body (load-bearing component), piston (pressure control), and spring (providing return force). Its operating principle is as follows: When the pedal is depressed, the piston compresses the brake fluid (pressure can reach 10-15MPa). The high-pressure fluid then flows through the lines, forcing the calipers to clamp the brake discs, thereby achieving braking. Key performance indicators include pressure stability (±5% fluctuation range) and durability (typically exceeding 100,000 cycles), which directly impact driving safety.
Brake master cylinder performance testing solutions can simulate real-world conditions, such as high-temperature (100°C) or low-temperature (-40°C) environmental testing.
Over more than a century of automotive industry development, engine technology has continuously innovated. As the vacuum source for vehicles, engine vacuum pumps have also undergone technological transformations.
