Key Points For Car Wheel Cylinders

1.The most important part of wheel  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 wheel cylinders,and it will also cause oil leaking.
2.Another key size of wheel 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 wheel cylinders casting parts.
3.The sizes control between the EPDM rubber boots is also very important.According to different codes of wheel 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.
