Specific analysis for the maintenance of brake pads
Brake shoes, commonly known as brake pads, are consumables that will gradually wear out in use, and when worn to the limit position, they must be replaced, otherwise they will reduce the effect of braking and even cause safety accidents. Brake shoes are a matter of life and must be treated with caution.
How to maintain brake pads, it mainly has the following six points:
1. Check the brake shoes every 5000 kilometers under normal driving conditions, not only to check the remaining thickness, but also to check the wear state of the shoes, whether the degree of wear on both sides is the same, whether the return is free, etc., and immediately deal with abnormal situations.
Second, the brake shoe is generally composed of two parts of the iron lining plate and friction material, do not wait for the friction material part to be worn out before replacing the shoe. For example, the front brake shoes of the Jetta car, the thickness of the new film is 14 mm, and the limit thickness of the replacement is 7 mm, including more than 3 mm of iron liner thickness and nearly 4 mm of friction material thickness. Some vehicles have brake shoe alarm function, once the wear limit has been reached, the meter will warn to replace the shoe. The shoe that has reached the limit of use must be replaced, even if it can be used for a period of time, it will reduce the effect of braking and affect the safety of driving.
Third, when replacing the brake pads provided by the original spare parts, only in this way can the braking effect between the brake pads and the brake disc be good and wear is small.
Fourth, when replacing the shoe, special tools must be used to push the brake pump back. Do not use other crowbars to press back hard, which can easily cause the brake caliper guide screw to bend, so that the brake pad stuck.
Five, after the replacement, to step on a few brakes to eliminate the gap between the shoe and the brake disc, resulting in the first foot no brake, prone to accidents.
Six, after the replacement of the brake shoe, it is necessary to run 200 kilometers to achieve the best braking effect, and the newly replaced shoe must be driven carefully.
The above six points are summarized for brake pad maintenance, hoping to help you.
