Someone who has been driving their car for a while might start to wonder why they are increasingly finding it necessary to have to step harder on the brake for the car to come to a halt. The reason is really simple; the brake lining which is found in the brake shoes is getting consumed. Usually, the brake lining is attached to the brake shoe itself and when someone steps the brake, as they try to bring the car to a halt, the shoe is pushed to apply pressure on the brake lining and as a result what happens between the brake lining and the inside of the drum is what will create braking. It is common for heat to be generated because after all, the friction that occurs is bound to give rise to heat. In terms of a train, the brake shoe is somewhat different because when it comes to a train, the brake shoe has a device called the brake block. In the earlier years, this brake block was made of wood but with changing times, it is now made of cast iron. Application of the brake makes the shoe apply pressure on the block and subsequently the wheels tread. This action does not only help the train to break but it also keeps the wheel rather well polished because it sort of cleans the wheel. Local brake shoes experts have shops that are stocked in brake shoes for whatever purpose and they will often provide you with all the relevant information related to the brake shoes.
