Certified brake systems are synonymous with safety.

Tests with disc brakes were first carried out in England during the last decades of the 19th century, but many more years were necessary for serial production.  As is very common in the car industry, car races, in particular Formula One, have been one of the main driving factors that enabled the spread of the disk breaking system.

Disc brakes are nowadays an essential component of modern cars. Even though small cars often still use drum brakes on the rear wheels due to lower cost simplicity and to make the handbrake more efficient. 

The braking system of any road vehicle is subject to extensive legislative standards and requirements in many regions around the world.

The European Union has defined strict quality and efficiency standards described in the  UNECE Regulations no. 13 n. 13H, n. 78 and n. 90. Brake system production companies have to comply with these regulations before put their products on the market.

ATS Group, with accredited test laboratories, can carrie out type approvals for braking systems and/or their components according to UNECE Regulations. More precisely we conduct:

  • Tests to define the braking distance and braking delay, reaction times, forces and other indicators of the braking process;
  • Tests of standard operating braking systems;
  • Tests of emergency braking systems;
  • Tests of hand (parking) braking systems – the ability to hold a vehicle’s position on a slope;
  • Cars and trucks;
  • Trailers and semi-trailers;
  • Hydraulic and pneumatic braking systems;
  • Tests of braking pads and other parts. 
  • Tests of ABS.

 How breaking system works?

When the driver push the brake pedal, the hydraulic system connected to the pump activates a caliper positioned on the opposite side of the steering rack. The caliper holds the brake pads and all components that enable it to move, such as wheel cylinders, which are usually made of aluminum or chromium plated steel. The brake pads also  are made by a metal base on which a layer of friction material, which can be of various types, is applied. The choice of material depends on whether one aims to maximize efficiency or durability.

The brake pads are squeezed by the caliper against the disc brake. The disc brake moves together with the wheel and thanks to these so created friction, the wheel stops turning which therefore stops the car. The brake disc can be made of different materials: iron, steel, ceramic or carbon ceramic, for high performance cars. It can be full with double contact surface or it can be daisy shaped with very particular plate profile carved or waived, often used in the motorcycle industry. Furthermore, it can be also vented. That is to say made of the two disks connected in such a way to allow air passage in between, which improves heat dissipation.

The ABS or anti lock brake system assist during the breaking phase. In order to prevent the wheels from blocking. Sensors are installed inside the wheels and communicate with a control unit at the very moment that one or more wheels lock up the control unit of the ABS intervenes under pressure of the hydraulic pump in order to lower the breaking force and therefore prevent a car from slipping. ABS systems also must to comply with safety Regulations in order to put on the market a safe and reliable product over time.
