Common Firenza problems included brake failure and engine fires. [54] In 1972, angry Firenza owners formed the "Dissatisfied Firenza Owners Association" and engaged in public demonstrations to publicize the car's quality problems and demand compensation from General Motors for repair costs and depreciation.
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]
Brake fade can be a factor in any vehicle that uses 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 brakes ...
The safety and quality of Tesla cars and services have been questioned. There have been hundreds of reports of sudden unintended acceleration, brake failures, and "whompy wheels" – collapsing wheels due to faulty car suspension. These safety and quality problems have been compounded in the past by the poor wait times of Tesla's customer service.
Multi-collision brake system (automatic post-collision braking system) to automatically brake the car after an accident to avoid a second collision.

Exhaust brakes are simpler in operation than an engine brake.Essentially, the exhaust pipe of the vehicle is restricted by a valve.This raises the pressure in the exhaust system, forcing the engine to work harder on the exhaust stroke of its cylinders, so again the engine is acting as an air compressor, with the power required to compress the air being withheld from the exhaust pipe, retarding ...
Railway brake malfunctions can produce sparks and cause forest fires. [6] In some very extreme cases, disc brakes can become red hot and set on fire. This happened in the Tuscan GP, when the Mercedes car, the W11 had its front carbon disc brakes almost bursting into flames, due to low ventilation and high usage. [7]
