The fault could be lack of hydraulic fluid, low brake fluid in the reservoir, a broken hydraulic line or a bad master brake cylinder. The sensor is used to detect pressure differentials in the hydraulic system. If the car alerts a fault in the hydraulic system and the system checks out, the sensor itself may have failed. [2]
The most common vehicle uses of master cylinders are in brake and clutch systems.. In brake systems, the operated devices are cylinders inside brake calipers and/or drum brakes; these cylinders may be called wheel cylinders or slave cylinders, and they push the brake pads towards a surface that rotates with the wheel (this surface is typically either a drum or a disc, a.k.a. a rotor) until the ...
The process is performed by forcing clean, bubble-free brake fluid through the entire system, usually from the master cylinder(s) to the calipers of disc brakes (or the wheel cylinders of drum brakes), but in certain cases in the opposite direction. A brake bleed screw is normally mounted at the highest point on each cylinder or caliper.

A larger diameter master cylinder delivers more hydraulic fluid to the caliper pistons, yet requires more brake pedal force and less brake pedal stroke to achieve a given deceleration. A smaller diameter master cylinder has the opposite effect. A master cylinder may also use differing diameters between the two sections to allow for increased ...
Brake fade can be a factor in any vehicle that utilizes a friction braking system including automobiles, trucks, motorcycles, airplanes, and bicycles. Brake fade is caused by a buildup of heat in the braking surfaces and the subsequent changes and reactions in the brake system components and can be experienced with both drum brakes and disc ...
When the driver depresses the brake pedal, pressure is transmitted to the brake master cylinder. [19] [20] [21] The brake cylinder piston pressurizes a system of hydraulic tubes, each of which leads to a different wheel. The brake fluid in the tubes, in turn, pressurizes the brake slave cylinders, which are on each wheel.
The forward travel of the rod causes the piston in the master cylinder to compress; this action pushes the brake fluid through the brake lines, which lead to the calipers. There, the fluid compresses the caliper pistons, which causes the brake pads to move inboard and contact the rotors. The resulting friction slows the vehicle.
