Brake discs are a complex mechanism made according to precise technical and engineering characteristics. This is a one-piece or prefabricated design that reduces speed, extinguishes energy with the help of friction and pressing the brake shoe friction against the surface of the disc.
The magnitude of the friction force also depends on the properties of the disk itself and the material from which the friction linings are made. The greater the mass of the car and the more powerful the acceleration speed of the vehicle, the more thoughtful the brake system should be. One of the popular models on the brake disc market is the Delphi brand.
Materials for the manufacture of brake discs
Among inexpensive materials with high wear resistance and good frictional properties, cast iron stands out. Such discs have a significant mass, the weight is twice as much as ceramic, which increases the load on the suspension. They can break or rust when wet, become very hot. Overheating can cause various technical failures.
Cast iron is not used for the manufacture of brake discs in racing and motorcycles, in contrast to carbon fiber and carbon fiber. Parts made of these materials are lightweight, resistant to temperature changes and retain their frictional properties. The disadvantages include high cost and demand for preheating.
As for stainless or ordinary steel, the material affects the reduction of frictional properties and the reduction of friction. The steel element is wider and less sensitive to elevated temperatures and water. Parts are actively developed, are expensive, but very durable and lightweight, have improved braking and frictional properties.
The advantages of ceramic discs include: wear resistance, long service life, the ability to travel 300, 000 kilometers or more. And among the shortcomings, one can single out the need for preheating and sensitivity to low temperature. Another minus - during operation, extraneous sounds, noise and creaking are possible.
Typology of brake parts
Brake discs can have cavities between two plates (ventilated) or be in the form of a solid plate with notches on a continuous perforated surface (non-ventilated).
Among the two types there are discs in which the hub is bolted to the ring. These two parts made of aluminum and cast iron are fixed to each other and cannot freely detach, representing a composite model. There are also discs cast from a single solid sheet of metal, modified to the desired state. In the first composite version, the disk has a lower weight, low cost of repair work to replace spare parts. For example, you can replace one ring. The advantages of composite disks include: quick cooling, low degree of possible deformation and changes.
Priorities should be set, focusing on the driving style. As a rule, radial disks do a good job with a harsh and aggressive style. Non-ventilated elements are not used as often, and a composite ventilated version is used at moderate loads.
Brand Description Delphi
In the 1990s, Delphi disconnected from General Motors and merged several companies into a single group, focusing on the manufacture and production of spare parts and systems. In the shortest possible time, she managed to gain high positions in the ratings, gain fame among other automobile giants and take one of the leading places among the five leaders in the world in working with auto parts.
Delphi is improving and constantly improving the level of service, produces high-quality systems, uses modern technology.
The number of outlets and representative offices in the European part is actively growing. The range of presented samples is expanding, an individual design is being formed.
Observing the specifics and focusing on the quality of the originals, the company supplies air conditioning systems, diesel engines, steering mechanisms, brake pads and Delphi brake disks. Product reviews are positive, parts are in demand among motorists and are popular.

Description of brake discs Delphi
In the manufacture of parts for braking, Delphi focuses on quality and tries to comply with it. The lineup contains a large number of brake parts that are designed for the most popular and popular car models. These are pads, drums, disks.
Studying reviews of Delphi brake discs, you can understand that the company is constantly improving product quality, conducting tests and tests to verify compliance with standards. The manufacturer focuses primarily on smooth and effective braking, improving compositions, increasing the power of its parts. In the reviews, the description of the Delphi brake discs is detailed and understandable to any car owner. These parts provide a fast reaction rate, give a sense of security.
It is important to constantly monitor the condition of the brake discs and pads, regularly check the wear resistance, smoothness of the specified actions, the condition of the calipers and pistons, the presence of grease, on which sliding and greasing depend. Untimely inspection can lead to creaking, leaks, breakdown of the brake system and deterioration of Delphi brake discs and pads. The reviews indicate that the brake parts are tested for noise, power and efficiency on a regular basis, the company uses high-quality technologies and a large number of new developments aimed at maintaining frictional properties and quiet response.
Expansion of the Delphi brake disc line
The applicability of Delphi brake discs, according to car owners, is quite high. At the moment, an innovation in the line is planned - the use of a special protective coating. The composition of mixed chlorine and zinc of silver color does not pose a danger to nature, but it perfectly retains the part, increases wear resistance, protects against corrosion, damage and other external factors that have a negative effect.
Product quality complies with the required standards. The mixture completely covers the surface of the disk (including the hub, outer and inner parts, ends, rim), which affects the service life and extends it twice, in contrast to partially coated parts. Installation of such a disk, as well as its replacement, is quick and easy, since the part does not need preliminary cleaning and is lubricated with an oil layer.
What are the Delphi brake discs? The reviews of company representatives contain information on models with perforation, mounting bolts, high carbon content.
Benefits
Delphi brake discs have a number of positive qualities, one of which is the use of good friction materials and their continuous improvement. This makes friction quiet, reduces wear, reduces dirt and dust. Special slots protect the friction material from cracking and remove moisture from the surface of the disc, and bevels help reduce noise.
Analyzing reviews of Delphi brake discs, motorists report that the possibility of simultaneous surface treatment is an important advantage of these parts. This significantly reduces the likelihood of differences in the thickness of the disk. The pluses include the control of excessive deviation of the friction surfaces and good adhesion due to the lower layer, which resists shear and fractional composition, minimizing vibration.
The cleanliness of the surface is also highly appreciated, with the help of which the pads better contact with the disk, providing brake power.
Reviews
The reviews on the Delphi brake discs indicate that they wear out evenly. The model has established itself in the market, has formed a trusting relationship with itself and has justified quality.
According to some reviews, Delphi pads do not always respond quickly to sharp braking on the track, they can buzz and raise dust under intense loads and at high speeds, while the resource is beyond doubt. At the same time, pads respond to braking better than factory products, which can be washed to metal, despite the time spent lapping.
Car owners are pleased with a good grip, lack of heating, affordable cost.
