What are brake discs? What does the brake disc mean

The brake disc (brake disc) is a very important part of the braking system, a good brake disc brakes stably, no noise, no shaking. The material of the brake disc is made of China's gray cast iron 250 standard, referred to as HT250, which is equivalent to the American G3000 standard. Brake disc is a cast product, due to the influence of climatic factors, the north is too cold, the south is too hot, so most of the production bases of brake disc are distributed in Shandong, Hebei, Shanxi this latitude area in China. Hope.

1. Solid brake disc.

A physical brake disc is a metal disc used for braking. This type of brake disc has a simple structure and is cheap. However, the heat dissipation effect is poor, so the thermal braking effect is relatively poor.

2. Ordinary ventilation type.

The normal ventilated type is an improvement on the basis of the physical brake disc. The heat dissipation performance has been enhanced, and the braking effect is more stable, which is currently used in most cars.

3. Perforated brake discs.

The perforated brake disc has better cooling, shortens the braking distance, and has a more stable braking effect, which is generally suitable for high-end cars.

4. Scribing brake discs.

The dust and debris attached to the brake disc can be discharged, and the rainwater can also be discharged when the road surface is wet in rainy days, so that the car will not be affected by excessive rain on the brake disc.

5. Ceramic composite brake disc.

It is made of a mixture of carbon fiber, graphite and silicon, whether it is hot or cold braking, it has better braking performance and longer service life, and is generally used on high-end cars or high-end sports cars.

Brake pads, also called brake discs, are used to rub against brake pads to decelerate.

Brake disc drum brake principle Drum brake is composed of brake floor, brake cylinder, brake shoe and other related connecting rods, springs, pins and brake drums. It is the use of hydraulic pressure to push the brake pads installed in the brake drum outward, so that the brake pads and the inner surface of the brake drum with the rotation of the wheels are rubbed, and the braking effect is produced. Drum pose.

Disc Disc Brake Principle Disc brake consists of a brake disc connected to the wheel and a brake caliper on the edge of the disc. When braking, the high-pressure brake fluid pushes the brake pad to clamp the brake disc to produce a braking effect. Disc brakes work on a disc that you pinch with your thumb and forefinger.

Hello! The brake disc, simply put, is a round disc that rotates when the car is moving. If the brake caliper clamps the brake disc and generates braking force, it clamps the brake disc to slow down or stop when the brake is pressed.

Brake discs brake well and are easier to maintain than drum brakes.

The brakes are currently available in disc and drum brakes, as well as air brakes.

Regarding the braking system of automobiles, the common braking devices at present mainly include drum brakes and disc brakes, among which disc brakes are sometimes called disc brakes, which are divided into ordinary disc brakes and ventilated disc brakes. In addition, sports cars like some luxury brands will also be equipped with more advanced "ceramic Zen brake discs", which of course also falls under the category of "disc brakes". One of the key components of a "disc brake" is the brake disc, which clamps the brake disc that rotates with the tires with a stationary brake pad, creating friction that reduces the wheel speed of the car.

Disc brakes consist of brake discs attached to the wheels and calipers with buckets blazing over the rims of the brake discs. When braking, the high-pressure brake fluid pushes the brake pad to clamp the brake disc, which creates a braking effect. The working principle of a disc brake can be described as a disc.

When pinching the dial with your thumb and forefinger, the dial will stop turning. With the continuous improvement of vehicle performance and driving speed, disc brakes have become the mainstream of the current braking system to increase the braking stability of the vehicle at high speeds. Disc brakes have excellent heat dissipation performance due to the fact that the brake discs of disc brakes are exposed to empty air.

When the vehicle brakes suddenly at high speed or brakes multiple times in a short period of time, the braking performance is not easy to decline, which can make the vehicle obtain better braking effect and improve the safety of the vehicle. And due to the fast response and high-frequency braking ability of disc brakes, many cars use disc brakes in combination with systems such as anti-lock braking systems, VSCs, traction control systems, etc., to meet the fast and corresponding needs of such systems.

The plate behind the crown brake disc is a brake disc protector that prevents dirt from entering while driving. There is no specific replacement interval for brake discs. When the mileage of the vehicle reaches 100,000 kilometers, the brake disc of the vehicle should be checked.

If it is damaged or worn to the limit, it should be replaced in time.

Steps to replace the brake disc:

1.Check the degree of wear and tear of the brake discs. During normal maintenance, it is not necessary to replace the brake disc. According to the actual situation, judge whether to replace the brake disc. The brake disc has a notch of more than 3mm and can be replaced.

2.Remove the front tire. To replace the brake discs, remove the two false front tires. You can see that the disc is the car brake disc.

3.Remove and secure the brake caliper screws. The brake discs are mounted on the front wheel bearings and are held in place by brake calipers on the outside. Remove the two 18 screws on the wrong brake and remove the brake caliper. Because there is an oil pipe connection on the brake caliper, lower it slowly to prevent the oil pipe from breaking.

4.Remove the old brake disc. The old brake discs were mounted on the front wheel bearings, which caused rust on the bearings and brake discs.

At this time, you can use a hammer to tap from behind the brake disc, and turn the brake disc as you knock, so that all four sides of the brake disc can be tapped. After a few taps, you can remove the old brake disc.

5.Install new brake discs. After aligning the eyelets of the new brake disc with the eyelets on the bearing, gently tap the inside of the brake disc with a hammer so that it is completely fixed on the bearing;

6.Install the brake caliper. Install the brake caliper in its original position, tighten the two set screws, and use the rotating bearing to observe whether there is any abnormal noise during rotation.

Do BMW 3 Series brake discs need to be replaced immediately?

Hello, I am your exclusive technician Yao Xindong, attentive, careful, dedicated to answering your car questions, for you to find the corresponding problem solutions and solutions! According to your description. Automobile brake disc, is the main component of the braking system, generally made of cast iron, the quality of the quality, directly affect the performance of the brake, send you the best, this needs to be replaced immediately or can be opened, the current 64,000 kilometers, brake pads are almost to the limit.

At this size, you don't need to replace it, if the brake disc is thin, you can directly replace the brake pads.

Change the brake pads first, and next time you need to replace the brake pads, you don't need to replace this thickness at present, BMW 4S shop said that I have reached the limit.

That's totally fine. The standard of the safety manufacturer, everything has to be changed, but it is actually driving. There is no problem at all, what about the brake pads, is it waiting for the alarm to be replaced.

Yes, oh dear, the spark plug and fuel filter element are not changed once every 40,000 kilometers, BMW three series.

Yes, dear.

Today, I will give my friends a brief introduction to the car brake disc, which is the introduction of the car brake disc, and I need to give a brief introduction to my friends.

Good brake disc braking is smooth, no noise, no shaking; The brake disc of a disc brake is a round plate that also runs when the car is moving. Many cars basically have front and rear disc brakes. Because the heat dissipation of disc brakes is better than that of drum brakes, it is not easy to cause thermal degradation in the high-speed braking state, so its high-speed braking effect is good.

That's all for today's brief introduction, how much do you know about brake pads and brake discs?
