Brake Pads Appear Uneven Wear Is How Is It?
Mar 15, 2018

Brake pads are consumables that will gradually wear out during use, and must be replaced when worn to the extreme position, otherwise it will reduce the effect of braking and even cause safety accidents.

Under normal circumstances, the front brake shoe wears relatively quickly, and the rear brake shoe uses a relatively long time. In routine maintenance, it should be noted that: Under normal driving conditions, the brake pads are inspected every 5,000 kilometers. It is not only necessary to check the remaining thickness, but also to check the state of wear of the shoes. Is the degree of wear on both sides the same? Freedom, etc., found that abnormal conditions must be dealt with immediately, and the brakes must not be replaced until the friction material is worn out.

The microscopic angle of uneven wear inside and outside is such that brake pads and disc grinding contracts are carried out, and brake pad materials are also softer than discs. No matter how uneven, the brake pads will always fit snugly into the brake disc.

If you are a new film in the old disk, you have to "grind a knife," and after about 50km, it will be fine. If it is only theoretically unfair, and the brakes are not shaking or shaking, then it is not a problem.

 Some vehicles have brake pad alarms. Once the wear limit is reached, the instrument will alarm to replace.

After replacing the brake pads, it is necessary to step on several brakes to eliminate the gap between the brake pads and the brake disc and cause the first leg to fail to brake, which is prone to accidents. In addition, 200 kilometers must be run in order to achieve the best braking effect, just brake pads must be moved carefully. The brake pad consists of two parts: one is a metal base plate and the other is a friction plate. When the brakes are applied, the friction plates contact with the brake discs to generate friction and act as brakes.

Obviously, friction plates will become thinner and thinner. The friction pad part of the new brake pad is generally 10 mm. When 5 mm is left, it is time to consider replacing the brake pad.

The causes of uneven wear inside and outside the brake pads and their treatment:


1 Brake fluid takes a long time, has impurities, or is false, causing the brake pump to return slowly. The brake pads wear out.

2 Brake pump rust, slow movement, resulting in the brake pads do not move, the outer brake pads friction and wear
