What should be noted in the daily inspection and maintenance of brake pads? Brake shoes commonly known as brake pads, belong to the wearing parts, in use will gradually wear to the limit position, must be changed, otherwise it will reduce the braking effect is not beautiful, and even lead to peace. Brake pads are about life safety, must be treated with caution.
The whole eve adopts the drum brake structure after the front drum, the wear and tear of the brake tile is generally faster, and the use time after braking is longer, the following aspects should be paid attention to in the daily inspection and maintenance.
Under the premise of normal operation, every 5000 kilometres of brake tile inspection time, not only to continue to find the thickness of the left side, but also to check the wear condition of the shoes, the degree of wear and tear is the same, whether or not it can be free to return, etc., and found that the abnormalities must be free in a timely manner.
Brake shoes are usually made of iron linings and friction materials, so there is no need to wait for the friction material sector to wear shoes. Jetta sedan front brake shoes, for example, its thickness is 14 mm, and the limit of the thickness of the variation of 7 mm, which is more than 3 mm of the iron plate thickness and the thickness of the friction material of about 4 mm. Some vehicles are equipped with brake shoe alarm function, once the wear limit is reached, the instrument will alarm to remind the change of shoes. It is necessary to change the shoes to the limit, even if they are used for a period of time, it will reduce the braking effect and affect driving safety.
When you want to change the supply of brake pads of the original parts, only then can the braking effect between the brake disc and the brake disc is not beautiful, it is best to change the school to change the shoes must be backed on the top of the brake wheel with a special tool. Can not use other pry bar hard pressure back, this is easy to make the caliper lead screw bending, so that the brake stuck.
After replacement, you must step on the brake a few feet to eliminate the gap between the shoe and the brake disc, so that the first foot has no brakes and is easy to present something. After replacing the brake shoes, they must be worn for 200 kilometres to achieve the best braking effect.
