Product Description

Auto Brake Disc 410*36mm Big Brake Rotor Fit Mazda RX7 Front Rim 21

The material of car calipers is wear-resistant and high-strength carbon steel. The hardness of this steel is that it can be used as a brake caliper for a long time without being worn out. Carbon steel is a steel with carbon content less than 1.35% (0.1% - 1.2%), which does not contain other alloy elements except iron, carbon and impurities such as silicon, manganese, phosphorus and sulfur within the limit. The properties of carbon steel mainly depend on the carbon content.

Brake caliper is a caliper device with the functions of decelerating, stopping or maintaining the stopped state of moving wheels. It is generally only used in disc brake system. The working principle of disc brake can be described as a plate. When holding the rotating plate with your thumb and index finger, the plate will also stop rotating. Your thumb and index finger play the role of brake caliper.

Steps for installing automobile brake caliper:

1. Install the brake caliper on the vehicle, and then tighten the fixing bolts to the specified torque;

2. Install the brake hose on the brake caliper and tighten the connecting bolts to the specified torque;

3. Add new brake fluid and exhaust the brake pipeline regularly;

4. Check the rotation resistance of the front disc brake;

5. Finally, install the tire.

First loosen the driving wheel bolt, lift the vehicle and remove the front wheel, loosen the brake hose connector, then install and fix the brake caliper, then connect the brake hose and tighten the bolt.

Installing car brake calipers is a relatively professional procedure. If it's not very strong to do it yourself, it's recommended to install it in the repair shop. The price of installing this is relatively moderate.

How many kilometers do you usually change the brake disc of a car

Braking is directly related to our driving safety. How often do we change the brake disc? In fact, there is no hard answer. After all, everyone's driving habits are different, so the wearing speed of the brake disc is also different. But in terms of normal use, the brake disc usually needs to be changed for tens of thousands of kilometers, and the front and rear brakes are also different.

1, Replace the brake disc every 100000 km

You should know not only how often to change the brake oil and brake pads, but also how often to change the brake pads. Under normal use, the brake pad can be used for up to 6 years, while the brake disc can be used for up to 10 years. It seems that it takes a long time, but the actual situation is not so ideal. Due to the complex road conditions in China, the braking system is adopted.

The actual service life of the brake disc is only about 70000 kilometers. Frequent braking and sudden braking will cause serious wear to the brake disc, so the real service life is often much shorter, but it all depends on everyone's driving habits. How do I know if my brake disc needs to be replaced? In fact, we can understand from these aspects.

2, Conditions for brake disc replacement

1. Abnormal braking noise.

The brake noise is abnormal, mostly because the brake pads are worn to the limit. Touching the brake disc will lead to scratches on the brake disc. At this time, replace the brake pads first. After all, the brake disc is still wear-resistant, but if the abnormal noise has not been eliminated after replacing the brake disc, please explain/

2. See the depth of the pit

There are three pits on the surface of the brake disc, about 1.5 mm. If the pits on both sides are ground flat, it means that the brake disc is thinner than 3mm, which will significantly lengthen the brake pedal travel and weaken the braking force. At this time, the brake disc also needs to be replaced.

3. Look at the brake disc indicator

Under normal conditions, the brake disc indicator is off. When the brake disc is excessively worn or fails, the indicator light will come on. When the brake disc is worn to the limit, the braking effect decreases, which directly affects the driving safety. Therefore, be sure to check the brake disc. After repair, the indicator light will go out.
