How to test low metal brake pads?

Do you know the detailed testing method of low metal brake pads? Low metal brake pads are the most critical safety parts, all brake effect is good or bad is the brake pads play a decisive role, here to remind the car enthusiasts to protect the brake system. Next is the introduction of the test method for low metal brake pads.

Here is the content list:

• Finger touch judgment

• Observe the grooves

• Judging by the thickness

• Listen to the sound

• The feeling of the foot

• Judging by the dashboard indicator light

Finger touch judgment

It is normal to see many small scratches on low metal brake pads due to frequent friction. However, if the scratches are significantly deeper and form a shape similar to a small groove, use your fingers to touch the edge of the groove. If the edge is sharp, the grooves are deeper and we need to consult the 4S store to see if they need to be replaced.

Observe the grooves

Most low metal brake pads have small grooves in them, known as wear indicator marks. When the low metal brake pads are worn to the point where the grooves are no longer visible, it means that they have reached their wear limit and need to be replaced immediately.

Judging by the thickness

The thickness of low metal brake pads will become thinner and thinner with the constant friction during braking in long-term use. Generally, the service life of low metal brake pads is about 40,000-60,000 kilometers, and the harsh car environment and aggressive driving style will shorten the service life in advance. When the design of the brake caliper of a model makes it impossible to see the brake pads with the naked eye, you can have the maintenance master remove the wheel to check the low metal brake pads when maintaining the vehicle. Both segments of the low metal brake pads have a raised mark, about 2-3 mm thick, which is the thinnest replacement limit for low metal brake pads. If you find that the thickness of the low metal brake pads is almost parallel to the mark, you need to replace the low metal brake pads immediately.

Listen to the sound

If there is an "iron scraping" sound when you tap the brakes (which may also be the effect of the low metal brake pads when they are first installed), the low metal brake pads must be replaced immediately. This is because the limit markings on both sides of the low metal brake pads have rubbed directly against the brake disc, proving that the low metal brake pads have exceeded their limits. In this case, when replacing the low metal brake pads, you should check the brake discs at the same time. When this sound occurs, the brake discs are often damaged (as shown in the picture below).

The feeling of the foot

If you feel a lot of effort when you step on the brake, you often need to press the brake deeper to achieve the previous braking effect, or if you feel the pedal position is low when you take the emergency brake, then it is possible that the low metal brake pads have lost their friction, and must be replaced at this time.

Judging by the dashboard indicator light

If the brake indicator on the dashboard lights up, it means that the brake system of the car is malfunctioning. You should focus on checking whether there is excessive wear on the low metal brake pads. If there is no obvious excessive wear on the low metal brake pads, it may be due to insufficient brake fluid or a problem in the wiring that causes the brake indicator light to be on, so you should go to a 4S store as soon as possible for inspection and repair.

Guangzhou IFK Auto Parts CO., LTD recommends that you send your low metal brake pads for repair as soon as they are detected to be defective. If the brake pads are faulty, your safety will not be guaranteed.
