Тормозные диски представляют собой сложный Mechanism made according to precise technical and engineering characteristics. This is a one-piece or prefabricated design that reduces speed, extinguishes energy by using friction and pressing the friction brake pads to the surface of the disk.
The magnitude of the friction force also depends on the propertiesthe disc itself and the material from which the friction linings are made. The greater the mass of the car and the more powerful the acceleration rate of the vehicle, the more thoughtful the braking system should be. One of the popular models on the brake disc market is the brand Delphi.
Materials for the manufacture of brake discs
Among the inexpensive materials with highwear resistance and good frictional properties of cast iron. Such disks have a considerable weight, the weight is twice the ceramic, which increases the load on the suspension. They may break or rust if they are wet, they become very hot. Overheating can cause various technical failures.
Cast iron is not used for the manufacture of brakedrives in racing and motorcycles, in contrast to carbon fiber and carbon fiber. Parts of these materials are lightweight, resistant to temperature changes and retain their frictional properties. The disadvantages include the high cost and demands for preheating.
As for stainless or ordinary steel,The material affects the reduction of frictional properties and reduction of friction. The steel element is wider and not so sensitive to elevated temperatures and ingress of water. Details are being actively developed, are expensive, but very durable and light, have improved braking and friction properties.
The advantages of ceramic discs include:resistance to wear, long service life, the possibility of passing 300,000 kilometers or more. And among the disadvantages are the need for preheating and sensitivity to low temperature. Another disadvantage is that during operation extraneous sounds, noise and squeaking 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 solid perforated surface (non-ventilated).
Среди двух типов имеются диски, в которых ступица bolted to the ring. These two parts of aluminum and cast iron are fixed to each other and can not 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 less weight, low cost of repair work on the replacement of spare parts. For example, you can replace one ring. The advantages of composite disks include: rapid cooling, a low degree of possible deformation and changes.

Description of brake discs Delphi
By production of parts for braking the companyDelphi is focused on quality and tries to match it. The line contains a large number of brake parts, which are designed for the most popular and sought-after car models. This pads, drums, discs.
Studying reviews of the brake discs Delphi, you canunderstand that the company is constantly improving product quality, conducts tests and tests to verify compliance with standards. The manufacturer focuses primarily on smooth and effective braking, improving the compositions, increasing the power of its parts. In the reviews, the description of brake discs Delphi is detailed and understandable to any car owner. These details provide a fast reaction rate, give a feeling of security.
It is important to constantly monitor the statebrake discs and pads, regularly check the wear resistance, smoothness of the specified actions, the state of the calipers and pistons, the presence of grease, which affects the sliding and salting. Failure to check in time may result in creaking, leaks, breaks in the braking system and wear on the brake discs and pads of Delphi. Reviews indicate that testing of brake parts for noise, power and efficiency is performed regularly, the company applies high-quality technology and a large number of new developments aimed at preserving friction properties and quiet response.
Expansion of the line of brake discs Delphi
Applicability brake discs Delphi, reviewscar owners quite high. Currently planned innovation in the line - the use of a special protective coating. The composition of mixed chlorine and zinc silver does not pose a danger to nature, but it perfectly preserves the part, increases wear resistance, protects against corrosion, damage and other external factors that have a negative impact.
Product quality is consistent with thestandards. The mixture covers the entire surface of the disc (including the hub, the outer and inner parts, the ends, the rim), which affects the service life and extends it twice, unlike partially coated parts. The installation of such a disk, as well as its replacement, is done quickly and easily, since the part does not need preliminary cleaning and is oiled with an oil layer.
What are the brake discs Delphi? Feedback from company representatives contains information on models with perforations, fastening bolts, high carbon content.
Benefits
Delphi brake discs have a whole range ofpositive 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 disk, and bevels help reduce noise.
Analyzing Delphi Brake Disc Reviewsmotorists report that the possibility of simultaneous surface treatment is an important advantage of these parts. This greatly reduces the likelihood of differences in the thickness of the disk. The advantages include control of excessive deflection of friction surfaces and good adhesion due to the lower layer, which resists shear and fractional composition, minimizing vibration.
It also appreciates the cleanliness of the surface, through which the pads are better in contact with the disc, providing the power of the braking system.
Reviews
In the reviews of the brake discs Delphi indicated that they wear evenly. The model has proven itself in the market, has formed a trustworthy attitude towards itself and has justified the quality.
According to some reviews, Delphi pads are not alwaysthey promptly react to sudden braking on the highway, they can buzz and raise dust under intense loads and at increased speed, while there is no doubt about the resource. In this case, the pads react to braking better than factory products that can wear down to the metal, despite the time it takes to grind in.
Car owners are pleased with a good grip, lack of heating, affordable price.
