How long does it take to change the brake pads (how much does BMW change the brake pads)

The car replacement of the brake pads is about an hour. The operation steps are as follows:



1. Prepare the jack, then lift the car, and then remove the tire.
2. Then remove the screw of the brake caliper, then remove the brake caliper, and remove the old brake pads.
3. Next, you need to push the brake piston back, and then install a new brake pad.
4. After putting the brake calipes back, you need to screw the caliper screw back to the required torque, and then put it back to the tire.
5. After the brake pads on both sides are replaced, you will see the brake oil in the brake oil pot overflow. For this phenomenon, you need to step on a few more brakes, and the liquid surface needs to be kept between MAX and MIM. The main reason for stepping on the brake is to improve the gap between the brake pads and brake discs, so that the pump piston is reset.
6. Finally, check the brake oil pump to see if it can work normally. After confirming that there is no problem, the brake pads have been replaced.



A few hundred yuan.


Domestic brake pads are cheap, and the quality is also available. There is no problem to use. The first-class domestic brake pads (BMW) are about 180-220; the imported is expensive. Our, Germany Taominon, Spain ReMSA, the price is relatively high, about 400-500.



also called the brake skin. In the car's brake system, the brake pads are the most critical safety parts. The quality of all brake effects is a decisive role in the brake pads, so good brake pads are the protector of people and cars.




Brake Lining is generally composed of steel plates, bonding thermal insulation layers and friction blocks. The steel plate should be painted to prevent rust. To ensure quality.


The insulation layer is composed of non -heat transfer materials, the purpose is to heat up. The friction block consists of friction materials and adhesives. It is squeezed on the brake disc or the brake drum during braking to produce friction during the brake, so as to achieve the purpose of the vehicle deceleration and brakes. Due to friction, the friction block will gradually be worn. Generally speaking, the lower the cost of the brake pads, the faster the cost.

NAO brake pads are good, but the price is more expensive. NAO brake pads are impact -free and non -metal. The abrasion -resistant and noise is small. The most important thing is environmental protection. The braking coefficient is high and environmentally friendly. Nowadays, there are no semi -metals, but most of the ceramics. NAO brake pads have small brake noise, less gray, and environmentally friendly friction materials.


currently add a lot of copper to the disk NaO. However, NAO currently has the disadvantages of high temperature decline. The characteristics of NAO brake pads determine the metal content. The first to be proposed by this concept is Japan, so their technology is relatively mature.

NAO means None Asbestos Organic, which is aspaonomy -free organic friction material, which contains metal ingredients. Having brake pads is a special metal -free type. In the process of studying the NAO brake pads, I found that the high temperature and heat decline cannot be avoided, but the developing formula of my research and development formula is relatively stable. The amount of wear between 0.36-0.4 is not large.


Setting the gap while contacting the brake pads is because there is a gap in the brake pads just changed. To change the brake pads, you must pump the sub -back first. The phenomenon.



Note: The wear between the brake disc and the brake pads is definitely not uniform, because the material used in the brake pads is not a pure metal block, but a metal carbon ceramic mixture. One -one, the surface is smooth, so the brake disc was grinded, and the groove appeared.


After changing the new brake pads, because the new brake pads are flat and smooth, there will be poor contact when they come into contact with the brake disc with a slight groove. The raised part of the brake disc surface is contacting the brake film, so that the contact area between the two will become gap.


Each model is different, it is not the same.

About 80 percent of the rear wheel brakes with Honda 125 series, Suzuki 125 series, Qianjiang 125, Qianjiang 150 and other motorcycle rear wheel brake pads, and very small parts of the agricultural small three car brake pads. It is usually iron brackets. The brake face is riveted with rivets. The front wheel brake hoofs and many light motorcycles such as Jinan Light Riding 50, New Continent 50, Suzuki 50, Construction-Yamaha 50, Jialing 50, Honda 50 and other universal.


Drum brake is fixed with the tire and rotated at the same speed. Drum brakes are composed of brake bottom plates, brake split pumps, brake hoofs and other related links, springs, tip nails, and brake drums. It is currently only used in the rear wheels. The cost of drum brakes is low and absolutely more powerful, and it is used in the rear wheels of small cars. However, its abrasion rate is high, so the overall cost is higher at the same time.





Simply put, the drum brake is the use of the static brake pads in the brake drum to rub the brake drum with the wheel rotation, so as to generate friction to make the wheel rotation speed Reduce brake device. When stepping on the brake pedal, the force of the feet will make the piston in the brake pump push the brake oil forward and put pressure on the oil circuit.     Pressure is transmitted to the brake split pistol of each wheels through the brake oil. The piston of the brake split pump pushes the brake pads outward, rubbing the inner side of the brake pads and the brake drum Speed \u200b\u200bto achieve the purpose of braking.
