Brake pads, also known as rotors or disks, are a critical part of disc brake systems utilized in cars and many other applications. Brake pads, which come in either solid rubber or thermoplastic rubber, are filled with a liquid that is either propelled onto the rotors by the brake fluid or is expelled from the brake system when the rotors are seized. Brake pads have an important role in preventing damage to the rotors and braking mechanism. The brake pads themselves do not wear out but rather develop a wearing surface which can impact the effectiveness of the braking mechanism. Brake pad wear also causes brake fade which can cause the braking system to work less effectively and could cause an accident.
Brake pads play an important role in preventing unwanted vehicle movement and control excessive vehicle lateral movements. They also help to keep the wheels attached to the tires. When the wheels and tires of a car or other vehicle come in contact with each other, a phenomenon called slip resistance causes the wheels to rapidly turn. This results in uneven braking, loss of control of the vehicle, skidding, and hydroplaning. Properly designed and properly fitted brake pads can minimize the effects of slip resistance by helping the wheels and tires resist lateral and angular movements.
Brake pads also play an important role in preventing brake fade. As the speed of the car increases, so do the number of times that the pads need to be decelerated. Due to this, friction between the pads and rotors increases and causes the pad wear to increase with time. When the friction is particularly high, it can reduce the life of the rotors and brake lights. When this happens, the driver should take care when applying pressure on the brake pedal to ensure that he does not put excessive pressure on the brake pedal. In addition, he should also take care to follow the manufacturer's instructions for the appropriate maintenance and care of the rotors and brakes.
The rotors and calipers are made of plastic and can be found on either side of the wheel. On newer cars, the rotors are made from aluminum and the calipers are made of synthetic plastics. Each of the two main components plays an important part in the performance of the car. The rotors play an active role in deterring and regulating the amount of friction and heat that flows onto the brake pads. The calipers are used to increase the brake grip during braking and reduce the amount of power required to break the vehicle.
Brake pads wear when they are subjected to extreme temperatures such as when driving in the heat. When the temperature reaches about 150 degrees Fahrenheit, the metal backing of the pad becomes brittle and the pad will crack when placed under a car's bonnet. The friction caused by the hot metal and the heat causes the metal backing to weaken and the pad will crack when heated. This cracking will allow more heat to be driven into the pad causing it to melt even further, causing the car to brake harshly.
Brake pads also wear differently depending on the type of vehicle as well as the model. For instance, a passenger car will have different performance specifications than an SUV. While both cars use identical pads, the SUVs will use the discs brake system, which is a little stronger and more complex than the drums. Disc brakes are very efficient and they do not make much noise.
After each brakes inspection, both cars should be cleaned. This means the brakes should be cleaned of all debris, dust, and dirt using a good quality vacuum cleaner and then the pads should be cleaned with a special pad cleaner. Both cars should be thoroughly inspected again using detailing clay to ensure that no metal filings were missed during the cleaning process. After the detailing clay is applied, the brakes should be inspected using both spot and optical inspection. Both types of inspections should rule out any problems that would require a re-installation.
Brake pads may be replaced if they show excessive wear such as near the rotor. Brake pads that show excessive wear also display signs of heating failure, meaning that the friction level is too high. Hot brakes deteriorate quickly, which results in hot brakes. A brake repair technician can check the condition of your brakes and can recommend either ceramic or semi-metallic pads, depending on the type of vehicle as well as the type of brake pads being replaced.
