Auto Brake Disc 400*36mm Rotor Floating Disc For Nissan GTR R35

We have these size auto brake disc:285*24/295*24/324*10/330*10/330*24/345*28/345*32/355*12/355*22/355*28/355*32/362*32/360*36/360*28/370*22/370*36/380*28/380*32/
380*34/380*36/390*34/390*36/400*34/405*34/405*36/410*36/420*40mm

1. Production technology: there are many kinds of brake discs, which are characterized by thin wall, and the disc and center are formed by sand core. For different types of brake discs, there are differences in disc diameter, disc thickness and two disc gap dimensions, and the thickness and height of disc hub are also different. The brake disc structure of single-layer disc is relatively simple. The casting weight is mostly 6-18kg.

2. Technical requirements: the outer contour of the casting shall be processed completely, and there shall be no casting defects such as shrinkage porosity, air hole and sand hole after finishing. The metallographic structure is medium flake type and graphite type, with uniform structure, Small section sensitivity (especially the small hardness difference) III. production process: most domestic manufacturers use clay sand Wet Mold, manual template mold and fat oil sand core. Individual manufacturers or individual varieties of castings use tree coated sand hot core box process, and some manufacturers also produce turntables on the molding line. Cupola is mostly used for smelting, and cupola and electric furnace are also used for combined smelting. Inoculation and treatment are carried out before the furnace The chemical composition of molten iron can be measured quickly so that it can be adjusted at any time.

How long do you use it to replace auto brake discs

Theoretically, the maximum wear limit of the brake disc is 2mm, and a new brake disc must be replaced after use. However, in actual use, most car owners do not strictly implement this standard. The replacement frequency shall also be measured according to their driving habits. The general measurement standards are as follows:

1. Look at the replacement frequency of brake pads. If the replacement frequency of the brake pads is very high, it is recommended to check the thickness of the brake discs. After all, if you spend more money on the pads, you use a lot of brakes, so you should check the brake discs regularly.

2. It is determined according to the wear condition: in addition to the normal wear of the brake disc, there is also the wear caused by the quality of the brake pad or brake disc and foreign matters during normal use. If the brake disc is worn by foreign matters, there are some deep grooves, Or if there is deviation in the wear of the disk surface (some places are thin and some places are thick), it is recommended to replace it, because the poor wear and deviation will directly affect our safe driving.
