Brake shoes, commonly known as brake pads, are consumables, wear gradually in use, when wear to the extreme position, must be replaced, otherwise it will reduce the effect of braking, and even accidents. The automatic transmission repair manufacturer introduces that brake shoes are vital to safety and must be treated with caution.

大多数轿车采用前盘后鼓式制动器结构，一般情况下前制动蹄片磨损的相对较快，后制动蹄片使用的时间相对较长，在日常的检查维护中应注意以下几个方面：

Most cars adopt the front and rear drum brake structure. Generally speaking, the front brake shoe wears relatively fast and the rear brake shoe is used relatively long. The following aspects should be paid attention to in daily inspection and maintenance:

1.正常行驶条件下每行驶5000对制动蹄片检查一次，不仅要检查剩余的厚度，还要检查蹄片磨损的状态，两边磨损的程度是否一样，回位是否自如等，发现不正常情况必须立即处理。

1. Check the brake shoe every 5,000 kilometers under normal driving conditions, not only to check the remaining thickness, but also to check the wear state of the shoe, both sides of the wear degree is the same, return is comfortable, found that the abnormal situation must be dealt with immediately.

2.制动蹄片一般由铁衬板和摩擦材料两部分组成，一定不要等摩擦材料部分都磨没了才更换蹄片。例如捷达车的前制动蹄片，新片的厚度为14毫米，而更换的极限厚度是7毫米，其中包括3毫米多的铁衬板厚度和近4毫米的摩擦材料厚度。一些车辆带有制动蹄片报警功能，一旦达到了磨损极限，仪表会报警提示更换蹄片。达到了使用极限的蹄片必须更换，即使尚能使用一段时间，也会降低制动的效果，影响行车的。

2. The brake shoe is usually composed of iron liner and friction material. It must not be replaced until the friction material is worn out. For example, the Jetta front brake shoe, the new thickness of 14 mm, and the replacement of the limit thickness of 7 mm, including more than 3 mm thickness of iron liner and nearly 4 mm thickness of friction material. Some vehicles have a brake shoe alarm function, once the wear limit is reached, the instrument will alarm to replace the shoe. The shoe must be replaced to reach the limit of use, even if it can be used for a period of time, it will reduce the effect of braking and affect the safety of driving.

3.更换时要换原厂备件提供的刹车片，只有这样，才能使刹车片和刹车盘之间的制动效果较好，磨损较小。

3. Change the brake pads provided by the spare parts of the original factory. Only in this way can the brake effect between the brake pads and the brake discs be the best and the wear is the least.

4.更换制动蹄片时必须使用专用工具将制动分泵顶回。不能用其他撬棍硬压回，这样易导致制动钳导向螺丝弯曲，使刹车片卡死。

4. when replacing brake shoes, special tools must be used to return the brake sub pump. It can not be hard pressed back by other crowbar, which will easily lead to the bending of the brake guide screws and block the brake pads.

5.更换制动蹄片后，一定要踩几脚刹车，以蹄片与制动盘的间隙，造成一脚没刹车，易出现事故。

5. After replacing the brake shoe, must step on several feet brake, in order to eliminate the gap between the shoe and the brake disc, causing the first foot no brake, easy to occur accidents.

6.变速箱维修厂家介绍制动蹄片更换后，需磨合200方能达到较佳的制动效果，刚换的蹄片须谨慎行驶。

6. Gearbox maintenance manufacturer introduces the replacement of brake shoe, need to run in 200 km to achieve the best braking effect, just changed shoe must be carefully running.
