  2. Brake fluid pressure sensor - Wikipedia

    en.wikipedia.org/wiki/Brake_fluid_pressure_sensor

    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]

  3. Power brakes - Wikipedia

    en.wikipedia.org/wiki/Power_brakes

    Vacuum boosters provide brake assist for the driver by multiplying the force out of the booster creating more than the force that was used to push on the brake pedal. The booster works by pulling the air out of the booster chamber with a pump or other vacuum source (typically the engine's intake manifold [1]), creating a low-pressure system ...

  4. Vacuum servo - Wikipedia

    en.wikipedia.org/wiki/Vacuum_servo

    In the US it is commonly called a brake booster. A vacuum servo, also known as a power booster or power brake unit, uses a vacuum, usually supplied by the engine, to multiply the driver's pedal effort and apply that effort to the master cylinder .

  5. Brake fade - Wikipedia

    en.wikipedia.org/wiki/Brake_fade

    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 ...

  6. Brake pad - Wikipedia

    en.wikipedia.org/wiki/Brake_pad

    Worn brake pads, contaminated brake fluid, faulty brake caliper, faulty master cylinder, loss of vacuum, loss of brake fluid Car pulls to one side when braking Faulty brake caliper, restriction in hydraulic system, brake pad lining(s) contaminated with oil or brake fluid, brake pads not replaced in pairs, brake pad not fitted correctly,

  7. Tell-tale (automotive) - Wikipedia

    en.wikipedia.org/wiki/Tell-tale_(automotive)

    Many vehicles have a red tell-tale to indicate that the parking brake is engaged or that there is a fault with the vehicle's braking system. [7] This tell-tale in most cases bears the ISO symbols for a parking brake and for a braking system emergency. In the past, US regulations required this tell-tale to bear the legend brake. [10]

  8. Emergency brake assist - Wikipedia

    en.wikipedia.org/wiki/Emergency_brake_assist

    By interpreting the speed and force with which the brake pedal is pushed, the system detects if the driver is trying to execute an emergency stop, and if the brake pedal is not fully applied, the system overrides and fully applies the brakes until the anti-lock braking system (ABS) takes over to stop the wheels locking up. [1]

  9. Brake wear indicator - Wikipedia

    en.wikipedia.org/wiki/Brake_wear_indicator

    The embedded sensor in the brake pad 2 contacts the rotor and creates a connection to ground of the sensor. The metal plate 3 contacts the rotor and creates a noise. This wear clip should be positioned so that the rotor contacts the clip before it contacts the brake pad. The rotor should push against that clip, not drag it away from the brake pad.
