Brake pads- The Necessity of Every Vehicle

Brake pad is the main component of brakes that apply pressure to the wheels and cause friction which helps in slowing the speed of the vehicle. Brake pads use friction to convert the kinetic energy to the thermal energy. Brake pads together make a capsule called brake caliper, facing the rotor. When the brake is applied, the brake pads press themselves on the rotor, which generates energy to stop the vehicle. When these pads squeeze themselves on the rotor, they cause friction that generates heat and stops the vehicle. Usually, there are two brake pads. Higher-level vehicles can use as much as six pads in the caliper. Brake pads constitute a very important component of brakes. Considering this, the brake pad companies constantly aim at providing the world-class quality of brakes or brake pads.  

A wise choice should be made while selecting the brakes or brake pads. The material should be such that it resists the great amount of heat that is generated due to the friction caused while applying brakes. They should also be capable to resist water asit might arise due to moisture after heat is generated. They should be able to get cool faster. They should help in the smooth application of brakes to ease and fasten the whole process.

Earlier asbestos was used for their manufacturing. But later on, it was proved that these possess serious health hazards so, they were replaced with other materials. Non-metallic materials like cellulose,aramid, semi-metallic material, fully metallic material, or ceramic materials like copper, etcare now used.They are made up of iron, copper, steel, and graphite all mixed. These are cost-effective and durable. They help in transferring the heat generated due to friction and helps in the long life of the brake pads. But they are a little heavy considering the metals used. Also due to heavyweight, more and more energy is required for their movement.

Some signs that indicate the need for replacing the brake pads. Usually, its the screeching noises that come when the brakes are applied. It is due to the metallic shim in the brake pads which are made for this purpose only. This indicates the need for replacement of brakes. Some vehicles have an in-built indicator for the replacement of brakes. When its light turns on, it means there is a need for replacement of brakes. One can even check the brakes by looking at the thickness of the brake pads. If they appear considerably thin, it means they have worn out and need to be replaced.

One can either go for complete replacement of brake or some parts. But eventually, all will get replaced to ensure the continuous and smooth operation of the vehicles. However, even till replacement, additional services should be done for the breaks. The replacement depends either on the distance covered by the vehicle or on the time-period of usage. Some replace their brake pads after they have covered a certain distance and some replace them after few years. Well established and well-reputed brake pad suppliers should only be trusted and preferred.
