Given that the master cylinder will wear through normal use and can become corroded over time, it’s essential to replace it in order to avoid the risk of brake failure. Find superior master cylinders at Eurocarparts.com for every model of car.
A vital part of your car’s braking system, the master cylinder converts the pressure created by your foot pressing down on the brake pedal into hydraulic pressure, which builds up as brake fluid becomes trapped. This hydraulic pressure sets the whole braking mechanism into action, ending with the wheel cylinders demobilising the wheels. The master cylinder is a complicated piece of machinery, itself having a number of components. These include the housing, bore, brake fluid reservoir, fluid level sensor, piston(s), rubber cap, return spring and, in a manual car, rubber boot. Hydraulic pressure is instigated when the spring, cup and pistons slide in the cylinder bore. As an extra safety measure, modern vehicles usually have dual master cylinders, each with a different system of brake-circuit operation. If one cylinder fails (perhaps through the loss of brake fluid), the other will be able to work alone until the malfunctioning cylinder can be replaced. A common cause of failure is contamination or loss of brake fluid; if brake fluid becomes hygroscopic (attracting water), it will affect the system.
