The brake disc is one of the mostresponsible parts in the design of any car. The safety of traffic depends on its serviceability. In today's article, we will examine which brake discs ("Ford Focus" 2nd generation including) exist, how to determine wear and what to look for when buying new items.
Several factors influence this.First, the operating conditions of the vehicle. For example, with frequent trips in the rain (in regions such as the Leningrad region), the disk can easily deform as a result of the impact on the next puddle.
"Ford Focus" of the second generation is supplied with elements designed for a resource of 200 thousand kilometers. However, with "Schumacher" driving this figure can easily be divided into 3.
How can I determine if a brake disc replacement is necessary? "Ford Focus" 2, like other cars on the European market, has the following symptoms of wear:
Однако не всегда по этим признакам можно determine the fault. The most accurate answer to the question of whether replacement of the rear brake discs "Ford Focus" 2, will help visual diagnostics. For more accurate results, use a caliper or micrometer to measure the residual thickness of the metal.
So, if the brake discs are on Ford Focus 2(restyling was carried out or not, it does not matter) have the deformations described above, they are urgently subject to replacement. First of all, when buying, you should pay attention to the material, because the element is constantly exposed to thermal loads.
To date, there are two types of elements:
The first type of disc consists of two plates.The latter may have perforations and incisions. Unlike the vented, the second type is a solid construction. In some cases, it is also provided with incisions.
The perforation itself can be either through, orjust in-depth. In the first case, the hole effectively removes heat and burnout products (the friction material of the pads). However, this design has a significant drawback - low strength. With intensive operation, the disc simply crashes.
Что касается второго типа с углубленной perforation, it is more reliable, since the hole is drilled not through, but only partially. In terms of efficiency, these products are almost inferior to their counterparts. For such brake discs "Ford Focus" 2 will say thank you himself, giving complete comfort from driving.
These elements can be integral and compositestructure. In the first case, the disc will be cast and processed from one part of the metal. The second type is a sort of "hodgepodge", which includes a cast iron ring, bolts and an aluminum hub.
Many motorists claim thatunventilated disks - this is the last century. This is partly true. But again, it is worth starting from the mass and power of the car. If this is a small-size "Focus" 1.4, which is used in a sparing, "vegetable" mode, it is not necessary to install perforated brake discs.
"Ford Focus" 2 modifications RS is equipped with a powerful2.5-liter engine. Therefore, when replacing the drive on such a car, one should definitely buy perforated elements. Such a car is already "in stock" designed for aggressive driving, and therefore the selection of disks requires special attention.
"Ford Focus" 2nd generation can be supplied andsuch elements. They, unlike analogues, have several types of ventilation ducts. The price of the product depends on their quantity, depth and method of application. Models of the budget class use direct channels. Such elements are suitable for semisportive driving. For sudden and frequent stops, they are unsuitable - they quickly overheat.
Это более дорогой вариант вентилируемых дисков.Here, the ventilation holes are twisted from the center of the hub to the rear of the car. Thanks to this design, the channels provide effective air loosening, which increases the degree of cooling of the disc. Radial elements are excellent for sharp and frequent stops, without causing overheating and deformation.
Often we are offered to buy goods on a veryattractive price. Sometimes this is really a discount from the store, but most often - a banal deception of the buyer. Under the brand name, you buy a frank "china". Buying new brake discs (Ford Focus 2 including), you need to carefully consider the choice.
Visually, it is possible to distinguish the way a disk is processed.If it is a perforated version, its working surface must be covered with small grooves. In production, such elements are poured into a large form, and then sharpened on a machine. The forgery is cast entirely from the mold, without further processing. With this method of production, the reliability of the element is significantly reduced. The risk of cracks and other deformations increases many times.
The next factor is the thickness.If you compare this indicator with the original and fake, then the latter is much smaller. Unfair producers often save on materials. They are not stopped even by the fact that such a disk is dangerous to exploit. The main goal is to get the maximum profit with minimal investments, selling frank junk at an affordable price.
Итак, вы выбрали и установили новые диски brake. Ford Focus 2 should then be run. At this time, you can not make sharp maneuvers and braking. Grinding element is about 200-300 kilometers. Further the element is used in the normal mode of loads. Experts recommend changing discs with pads, even if their wear is minimal. It is desirable that they were the same brand. Also do not forget to pump the brakes before leaving. The liquid itself should be changed every 2 years, as it absorbs moisture strongly.
