Brake Pads Pay Attention To Detail At The Time Of Purchase
Brake pads in the car's braking system is the most critical safety parts, all the braking effect is good or bad brake pads play a decisive role, the brake pads generally by the steel plate, bonding insulation layer and friction block, which is Composed of non-heat transfer material, the purpose is to heat. The friction block is composed of friction material, adhesive, brake is squeezed in the brake disc or brake drum on the friction, Brake Pad so as to achieve the purpose of vehicle deceleration brake. Due to friction, the friction block will gradually be worn, in general, the lower the cost the greater the coefficient of the brake pads wear faster. Brake Pad After the use of friction material to replace the brake pads, or steel plate and brake disc will be in direct contact.
Semi-metallic brakes
Basically most of the cars when the factory brake pads are the formula, of course, this brake is the cheapest standard, this brake pad coefficient of friction is generally low friction coefficient of about 0.4 shorter life, but also some manufacturers The friction coefficient of this brake pads to do a high, of course, Brake Pad this is also a disadvantage of prone to noise. Generally in the Japanese car to use this brake is very easy to produce noise This is also inextricably linked with the brake disc.
Small brake pads, the price of this brake pads slightly higher than the semi-metal, this formula brake pads are in the end product, Brake Pad but in the eyes of consumers do not recognize, in fact, the cost of this brake is still very high , It is difficult for consumers to distinguish the difference between this brake pad and semi-metallic brake pads so customers are difficult to choose, Brake Pad this is the reason consumers do not recognize, less metal brake pads for any car.
Now on the market a lot of ceramic brakes, of course, "the name of" the product, different manufacturers do ceramic brakes are not the same, their performance is almost the same as the ceramic brake material, of course, ceramic fiber, All know that the ceramic is very hard wear-resistant, different manufacturers of ceramic brake pads using the raw materials, not the same also led to the price difference between the ceramic brake pads themselves, the price difference also led to the ceramic fiber excellent and poor, of course, this difference In the eyes of consumers can not tell, even if the manufacturers are difficult to distinguish, Brake Pad only after use will know the quality of the better than poor. The real ceramic brakes also contain aramid fiber, in the service life and brake pads performance, are far superior to the above formula brake pads. Of course, the price is more expensive!
When you replace the brake pads when the purchase of qualified products must be in the purchase of some manufacturers to save costs to reduce prices often cut corners Some should be friction surface 1.5cm made of 1.2cm, in the steel back should use 0.5cm But the use of 0.4cm these consumers carefully observed can be used to see the naked eye.
The life of the brake pads, usually according to the owner of the individual braking frequency, road conditions may be. Generally speaking, Brake Pad the brake pads in the driving 5-8 million kilometers or so need to be replaced, if the degree of wear and tear calculated by a third limit.
Here are some special cases to note:
1, novice brakes generally step on the more consumption will be larger.
2, automatic transmission than the manual file fee brake pads, because the automatic shift is to rely on the accelerator pedal and brake pedal.
3, often open the city's car, brake pads will be faster than the highway traffic quickly open. Because often open the city car, often to stop and go, with the brakes will be more. Take the road may take tens of kilometers to slow down or stop, with the opportunity to brake is relatively small.
4, load a large car, brake pads loss. The same speed of the case of slow down the brake, the weight of the car inertia, the need for friction on the brake pads on the large, so wear large.
