A few days ago, I went to the 4S aftermarket shop for maintenance and was told that the front brake pads were badly worn, and now only 3 mm thickness is left.

The car has been driven for more than 17,000 kilometers, and the brakes are not very hard, and usually drive gently, so why is it so badly worn?

Is there something wrong with it?

I need to change the brake pads, what kind is more suitable for the Cruz?

What is the price?

1. the degree of wear and tear is mainly directly related to the material of the brake disc and brake pads, so the uneven material of the brake pads is a possibility.

2. often turning brakes, the left and right wheels are not balanced, which will also lead to inconsistent wear.

3. One side of the brake disc may be deformed.

4. The brake distributor pump does not return to the same position.

5. Large difference in the length of the left and right brake fluid pipes

6. The telescopic rod is sealed by a rubber sealing sleeve, but if water or lack of lubrication is present, the rod cannot be freely telescoped, the outer piece of the brake pad cannot leave the brake disc, and the brake pad will wear extra.

7. The braking time of the left and right brakes is not consistent

8. Suspension problem

9. ABS control strategy has problems, resulting in unequal pressure in the pipeline, resulting in uneven.

10. The brake itself is a problem, the brake caliper piston responds badly, resulting in long-time wear.

11. Four wheel alignment problem

12. the entire brake system pipeline is not smooth, resulting in uneven brake fluid flow.

The original brake pad is too soft, change to a better high-temperature resistant brake pad

Causes of severe brake pad wear.

Bad quality of brake pads leading to non-wear resistance.

Driving habits and exercising road conditions are related, and daily congestion will lead to rapid wear.

The correct method of car brake pads maintenance

Under normal driving conditions, brake shoes should be checked once every 5,000 kilometers, not only to check the remaining thickness, but also to check the state of wear of the shoes, whether the degree of wear is the same on both sides, and whether the return position is free, etc. Abnormal conditions must be dealt with immediately.

Brake shoes generally consist of two parts: iron lining and friction material, so do not replace the shoes until the friction material is worn out.

For example, the front brake shoes of the Jetta, the thickness of the new piece is 14 mm, and the limit of the replacement thickness is 7 mm, including more than 3 mm of iron lining plate thickness and nearly 4 mm of friction material thickness.

Some vehicles have a brake shoe alarm function, once the wear limit is reached, the instrument will alarm to prompt the replacement of shoes. Reached the use limit of the shoes must be replaced, even if it can still be used for a period of time, will reduce the effectiveness of braking, affecting the safety of driving.

Only in this way can the brake pads and brake discs have the best braking effect and the least wear.

When replacing the shoes, you must use a special tool to push back the brake distributor pump. You cannot use other pry bars to press back, which will easily lead to the brake caliper guide screw bending and making the brake pads stuck.

After replacing, be sure to step on the brakes a few feet to eliminate the gap between the shoes and the brake disc, resulting in the first foot without brakes, prone to accidents.

After the brake shoes are replaced, they need to be broken in for 200 km to achieve the best braking effect, and the shoes just replaced must be driven with caution.
