Brake Disks:

Brake disks Rampa auto spare part sells brake discs of the brands Rrudforce and Brembo. At our warehouse is available the whole range of tie rods for industrial vehicles. Emporio Rossi sells only high quality longitudinal tie rods, at the most advantageous prices since they are original equipment. In this type of spare parts, safety comes first and it is highly inadvisable to choose a cheap spare part. The longitudinal tie rod is the first linkage element that starts from the steering box and joins the steering box to the steering column transmission. Normally it has a fixed head and a replaceable head; if the fixed one is damaged, it is compulsory to replace the whole tie rod, while in the other case it is convenient and possible to replace only the head.

The brake disc is an important component of the brake system. If the brake system is to be able to decelerate the vehicle in safety and comfort at all times – bringing it to a complete stop if necessary – the brake disc must combine with the brake pads to generate a brake torque (a brake force). This torque is transmitted to the wheel hub and from there to the wheel rim. During braking, the vehicle’s kinetic energy is converted into thermal energy due to friction between the brake pads and the brake disc, thereby enabling a reduction in speed to be achieved. 90% of the heat generated during braking penetrates the brake disc initially, where it is buffered. After this it is passed on to the ambient air. The brake disc thus functions like a heat exchanger. However, its ability to absorb heat is limited. Therefore, the heat must be dissipated to the ambient air quickly if damage due to overheating is to be avoided. .


During downhill driving, the friction ring can reach temperatures of up to 700°C (red heat). Ventilated brake For this reason, ventilated brake discs are very often used for better cooling – primarily at the front axle. Their surface area is much larger and better suited for heat exchange. Compared with ventilated brake discs, solid brake discs can only dissipate heat to the environment more slowly. The friction rings on ventilated brake discs are interconnected by means of webs in the shape of ribs or domes. The rotation of the brake disc generates air suction which draws air out from the inside of the brake disc through a ventilating duct. The tiny particles of air that this causes to come into contact with the surface of the brake disc absorb the thermal energy and transport it outwards. Perforated or grooved brake discs Even more effective cooling can be achieved with perforated or grooved brake discs. These types of disc also benefit from being less sensitive to wet. However, they are more expensive and can in some circumstances generate much more noise during braking​
