Brake discs are complex pieces of machinery manufactured to precise specifications and engineering specifications. This is a one-piece or prefabricated structure that reduces speed, absorbs energy using friction and pressing the brake pad frictions against the surface of the disc.
The magnitude of the friction force also depends on the properties of the disc itself and the material from which the friction linings are made. The greater the mass of the car and the more powerful the speed of acceleration of the vehicle, the more thoughtful the braking system should be. One of the popular models on the brake disc market is the Delphi brand.
Materials for making brake discs
Among inexpensive materials with high wear resistance and good frictional properties, cast iron stands out. Such discs have a significant mass, twice the weight of ceramic discs, which increases the load on the suspension. They can break or rust when exposed to moisture, they get very hot. Overheating can cause various technicalbreakdowns.
Cast iron is not used for the manufacture of brake discs in racing and motorcycles, unlike carbon fiber and carbon fiber. Parts made of these materials are light, resistant to temperature changes and retain their frictional properties. The disadvantages include high cost and demanding preheating.
As for stainless steel or ordinary steel, the material has the effect of reducing friction properties and reducing friction. The steel element is wider and not as sensitive to elevated temperatures and water ingress. Parts are being actively developed, are expensive, but very strong and light, have improved braking and frictional properties.
The advantages of ceramic discs include: wear resistance, long service life, the ability to cover 300,000 kilometers or more. And among the shortcomings can be identified the need for preheating and sensitivity to low temperatures. Another disadvantage is that extraneous sounds, noise and creaking are possible during operation.
Typology of brake parts
Brake discs can have cavities between two plates (ventilated) or be in the form of a single 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 pieces of aluminum and cast iron are fixed together and cannot be loosened freely, 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 on the replacement of spare parts. For example, you can replace one ring. The advantages of compound discs include: fast cooling, low degree of possible deformation and change.
Priorities should be based on driving style. As a rule, radial discs do well with sharp and aggressive styling. Non-ventilated elements are used less often, and the composite vented version is used for moderate loads.
Delphi brand description

Description of Delphi brake discs
When manufacturing brake parts, Delphi focuses on quality and strives to match it. The line contains a largethe number of brake parts that are designed for the most popular and sought-after car models. These are pads, drums, discs.
Reading reviews of Delphi brake discs, you can understand that the company is constantly improving product quality, testing and testing to ensure compliance with standards. The manufacturer focuses, first of all, on smooth and efficient braking, improving the compositions, and increasing the power of its parts. In the reviews, the description of Delphi brake discs is detailed and understandable to any car owner. These details provide a fast reaction speed, give a sense of security.
It is important to constantly monitor the condition of the brake discs and pads, regularly check the wear resistance, the smoothness of the specified actions, the condition of the calipers and pistons, the presence of lubrication, which affects slip and clogging. Late inspection can lead to squeaking, leaks, breakdown of the brake system and wear of Delphi brake discs and pads. Reviews indicate that brake parts are regularly tested for noise, power and efficiency, with high quality technology and a large number of new developments aimed at maintaining frictional properties and quiet response.
Expansion of Delphi brake disc line
The applicability of Delphi brake discs, according to car owners, is quite high. At the moment, an innovation is planned in the line - the use of a special protectivecoatings. The composition of mixed chlorine and silver zinc does not pose a danger to nature, but perfectly preserves the part, increases wear resistance, protects against corrosion, damage and other external factors that have a negative impact.
Product quality meets the required standards. The mixture completely covers the surfaces of the disc (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 to be cleaned and is lubricated with an oil layer.
What are the Delphi brake discs? Reviews from company representatives contain information about models with perforations, 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 quieter, reduces wear, and reduces dirt and dust ingress. Special slots protect the friction material from cracking and remove moisture from the disc surface, while bevels help reduce noise.
Analyzing reviews of Delphi brake discs, motorists report that an important advantage of these parts is the possibility of simultaneous surface treatment. This greatly reducesthe likelihood of differences in disc thickness. Benefits include control of excessive deflection of friction surfaces and good traction due to the bottom layer that resists shear and fractionation, minimizing vibration.
Also commended is the cleanliness of the surface, which allows the pads to better contact the disc, providing brake power.
Reviews
Reviews of Delphi brake discs indicate that they wear out evenly. The model has proven itself in the market, has formed a trusting attitude towards itself and justified the quality.
According to some reviews, Delphi pads do not always respond quickly to sudden braking on the highway, they can hum and raise dust under heavy loads and at high speeds, while the resource is beyond doubt. At the same time, the pads respond to braking better than factory products, which can wear down to metal, despite the time spent on grinding in.
Car owners are pleased with good grip, no heating, affordable price.
Comparison of Delphi brake discs and pads with other brands
On special forums you can read reviews about Delphi brake discs. Motorists who have already purchased spare parts or are just planning a purchase leave an opinion about the manufacturer of these parts. Compared to other brands (Bilstein, TRW, Ferodo, Brembo, Zimmermann, Kayaba, etc.), Delphi discs are characterized by uniformwear.
Why change Delphi brake discs? User reviews indicate replacement conditions that equate to the following indicators: two pad changes to one disc change. Delphi brake discs are softer than other brands, and in most cases there is no squeaking or whistling when they are installed.
