Key Points For Car Brake Cylinders

1.The most important part of brake cylinder body parts is the surface roughness inside of it,the surface roughness shall be strictly controlled at Ra0.4um,if not,the friction force between the pistions and wheel cylinder casting parts will be bigger,so it will directly affect the working life of brake cylinders,and it will also cause oil leaking.

2.Another key size of brake cylinders is the space between the pistons and wheel cylinders casting parts,the allowable tolerance of pistions is -0.04mm to -0.07mm,and the allowable tolerance of wheel cylinders is +0.052mm,these sizes shall be strictly controlled,otherwise it will affect the work schedule of pistions and the gas tightness inside of the brake cylinders casting parts.

3.The sizes control between the EPDM rubber boots is also very important.According to different codes of brake cylinders,there are different sizes of boot slots,so we produce the boots on the baiscs of various sizes of boot slots,if not,the boots can't guarantee a good gas tightness,which will cause brake fluids leakage.



Production Techniques For Car Brake Cylinders

As to guarantee that each of our brake cylinder can meet the OE standards,we bought the most advanced CNC machines to manufactur the accurate sizes of different brake cylinders casting parts,especially the surface finishing inside of them,also we have the full-automatic machines to make these installing holes with accurat sizes.All of our production lines are controlled by computers,which can help us to make better quality control system,so our brake cylinders will never let you down.



Test Programs For Car Brake Cylinders

In order to make sure that each of our brake cylinder can meet the quality standards of clients,we have developed different kinds of test programs.There are five test programs of brake cylinders that are the most effective methods to value the quality of a brake cylinder,they are the test of size and appearance,the hardness test,the strength of extension test,metallography detection and the durability test,together all these tests can not only check the outside sppearance and sizes of our brake cylinders,but also guarantee some important features of brake cylinders,such as the extension strength,the metallpgraphy detection is a kind of test to ensure that the internal chemical components of the brake cylinders is up to the international standards.



Stylish Packings For Car Brake Cylinders
