What kind of iron is the car brake pad, and what is the iron cover behind the brake pad called

There are two types of brake pads: metallic brake pads and carbon-ceramic brake pads. Brake pads are also called brake pads, in the braking system of automobiles, brake pads are key safety parts, and all brake effects are decisive for brake pads.

Brake pads are generally made up of steel plates, bonded insulation, and friction blocks. The working principle of brakes mainly comes from friction, using the friction between brake pads and brake discs and tires and the ground to convert the kinetic energy of the vehicle into the heat energy of friction to stop the car. A good and efficient braking system must be able to provide stable, sufficient and controllable braking force, and have good hydraulic transmission and heat dissipation capacity to ensure that the force exerted by the driver from the brake pedal can be fully and effectively transmitted to the master cylinder and each sub-cylinder, so as to avoid hydraulic failure and brake decline caused by high heat.

I really don't know this, but I want to remind you that when you step on the brakes, if the brake shoes make a sound, this is an alarm, this is the brake shoes are going to be polished, and they should be replaced immediately, because in a few days you can't hear it even if you step on the brakes, at this time the brakes are almost worn out, and when you step on the brakes when you are not fast, you can't feel that the brake shoes are about to be worn out, but if you are emergency braking, then the car can't stop, which is why some cars fail to brake during emergency braking, in fact, it is not brake failure, There are no brake shoes anymore. In order to save money, some drivers do not replace the brake shoes in time.

Some fake brake shoes do not have an alarm when they are about to be polished, which requires you to pay attention to how many kilometers the car has run, and when it is almost this kilometer, if you feel that the brakes are not stopped immediately, replace them immediately.

Brake pads are not simply made with iron. See Materials: Asbestos brake pads, "semi-metallic" hybrid brake pads, asbestos-free organic brake pads (NAO), and ceramic brake pads used in racing cars.

Not iron. Composition of raw materials for brake pads.

Generally, it is divided into four parts: binders, reinforcing fibers, friction performance modifiers, and fillers

Asbestos-free organic brake material, a new type of nao raw material. Wait.

It's not iron, it's iron. It is asbestos plus other materials.

1. It works. The two brake pads are clamped like clips for drying clothes through elastic wires.

on, let the brake pads with the brake discs.

Always at the appropriate angle of the front section slightly tighter, so as to overcome the tendency of the brake Yuling old car plate to lean back due to friction when braking, and achieve uniform wear.

2. The second is the ingenious design so that it has the function of passive alarm device, when the brake pad is worn, the thickness is reduced, the steel wire will gradually approach the brake disc, before the wear to the safety line, the steel town rising wire will contact with the edge of the brake disc to make a harsh friction sound, so as to play a reminder role, and even if the steel wire is broken, the replacement cost is relatively low.

The iron sheet gasket on the back of the brake pad is called the sound insulation sheet, also called the silencer damper pad, each brake pad has two pads (one is flat, and the outside side has an edge, stuck on the brake pad), the role can not be underestimated, called the silencer shock absorber, designed to prevent the brake from making abnormal noise, used to eliminate the shaking of the car and the brake pad? Resonant noise.

If it is not installed, it may ring after a while.

This iron plate is in the repair kit of the sub-cylinder, and the muffler does not belong to the component parts of the brake pad, but is the component of the sub-cylinder.

There is also a piece of iron under the stainless steel color in the picture, a flat, black (a total of two pieces) <>

Hello! This thing is generally called a wall panel. Be careful not to lose your shape when replacing your tire. If it is deformed, it is easy to make abnormal noises. [If you have a problem with the car, ask the car master.] 4S shop professional technician, 10 minutes to solve. 】

Hello, sub-cylinder, tighten the brake pad device, I hope it can help you. [If you have a problem with the car, ask the car master.] 4S shop professional technician, 10 minutes to solve. 】

Hello, there is a problem with the car called the dust sheet,,, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

Iron Sheet Wu is a warning effect.

The braking system is when the brake pedal is pressed, the brake fluid in the brake master cylinder is pressed, and the liquid transmits the pressure through the pipeline to the piston of the brake caliper of each wheel, and the piston drives the brake caliper to clamp the brake disc, creating a huge friction force to slow down the vehicle.

If in the process of daily driving, the brake hears a harsh metal whistling sound, at this time you should pay attention, this is the alarm iron plate on the brake pad has begun to wear out the brake disc, so there will be this kind of sharp metal sound.
