操作说明
检查你的 1989 奔驰 190D 的制动液非常简单，建议每月进行一次。 在一些 奔驰车型 上，用户手册建议在检查制动液液位之前，踩踏制动踏板 25 次，但请务必查阅您的 1989 190D 用户手册，确认是否适用于您的车辆。 除了检查制动液液位，还应观察 190D 中制动液的颜色。如果颜色发暗，或者距上次更换已超过 2 年，应考虑更换，以延长价格昂贵的内部部件的使用寿命。如果需要为 190D 添加制动液，务必查阅车主手册，确认应添加的正确类型；可能是 DOT 3、DOT 4，或称为硅基制动液的 DOT 5。 请务必丢弃使用超过一年的制动液瓶装——制动液会从空气中吸收水分，液体中的水蒸气会迅速导致190D的制动管路生锈。

Checking the brake fluid in your 1989 Mercedes-Benz 190D is easy and should be done once a month. On some Mercedes-Benzs, the owners manual suggests pumping the brake pedal 25 times before looking at the fluid level, be sure to check your owners manual to see if this applies to your 1989 190D. In addition to checking the brake fluid level, you want to look at the color of the brake fluid in your 190D - if it is dark in color or it has been more than 2 years since you have changed it, you should consider having it changed - this will help make the internal components (which are expensive) last much longer.If you need to add fluid to your 190D, it is important to check your owners manual for the correct type to add - it likely be either DOT 3, DOT 4 or DOT 5, also known as silicone brake fluid. Be sure to discard bottles of brake fluid that are over a year old - brake fluid sucks the moisture out of the air and the water vapor in the fluid can quickly rust out the brake lines in your 190D.
