We often underestimate the life threatening event of failing brakes. Most car accidents happen as a result of under-performing brakes or brakes that just does not cope in poor road conditions.
Brakes evolved quite a bit over time and there are several brake systems available in including frictional brakes, hydraulic brakes, electromagnetic brakes commonly found in hybrid or electrical vehicles as well as parking or emergency brake systems.
There are numerous additional mechanisms that are involved to warrant car brakes function well in a variety of road situations and circumstances.
Kinds of Brake Systems
Frictional Brake System
Frictional brake systems are found in many automobiles. These are service brakes, and normally found in two forms; pads and shoes. These brakes use friction to stop the automobile from moving. They mostly include a rotating device with a stationary pad and a rotating weather surface. The shoe will tighten and brush against the outside of the turning drum, alternatively on a drum brake, a rotating drum with shoes will expand and rub against the inside of the drum.
Hydraulic Brake System
Hydraulic brake systems compose of of a master cylinder that is nourished by a reservoir of hydraulic braking fluid. This is connected by a range of metal pipes and rubber fittings which are attached to the cylinders of the wheels. The wheels contain two opposite pistons which are located on the band or drum brakes which pressure to push the pistons apart forcing the brake pads into the cylinders, thus causing the wheel to stop moving.
Electromagnetic Brake System
These kind of brakes are mostly found in hybrid vehicles. It uses an electric motor to charge the batteries and regenerative brakes. Some buses use a subordinate retarder brake with an internal short circuit and a generator. A rising style of brake system, electromagnetic brakes use an electric motor that is included in the automobile which help the vehicle come to a stop.
Parking and Emergency Braking Systems
Parking and emergency braking systems use levers and cables where you must use mechanical force (or a button / small lever in modern vehicles), to stop the vehicle in the case of emergency or parking on a hill. These braking systems sidestep standard braking systems in the occasion that the regular braking system fails.
