Why is the mileage of brake pads used different for each vehicle?

[Catalog:News] [Date:2021-10-22] [Hits:] [Return]

Some vehicles only travel 30000-40000 km, and the brake pads are worn to the limit, but there are still plenty of brake pads after driving 60000 km. Why is the service life of brake pads so different?

In fact, there are many reasons affecting the service life of brake pads: driving habits, driving road conditions, brake pad formula, etc., among which the brake pad formula has the most direct impac

What kinds of materials are common brake pads made of?

1. Semi metallic material formula

About 30% - 65% of the friction materials of semi-metallic brake pads are metal materials, including copper, iron, etc

It is characterized by fast heat dissipation, high temperature resistance and low price

The disadvantage is that the noise when braking will be relatively large, and the metal material will have great wear on the brake disc

At present, the original supporting brake pads used in medium and low-end models are naturally characterized by their low price

2. Low metal material formula

Low metal brake pads belong to the improved version of semi metal, and there is no difference in appearance

The metal composition in the low metal formula is lower than that in the semi metal formula, and the damage to the brake disc is small

At the same time, it can ensure the stability of heat dissipation and friction coefficient at high temperature

High quality low metal formula is often used in medium and high-end models

3. Nao material formula

Nao brake pads are asbestos free organic friction materials, containing aramid fibers and a small amount of metal materials

The advantages of Nao brake pads are short running in period, low noise, less wear to brake discs, less dust and long service life. In addition, the friction coefficient can remain stable at high temperature

The braking force attenuation caused by material melting during long-time or high-speed braking is avoided, which greatly improves the safety

Different brake pad formulations are applicable to different models and have their own advantages. Their advantages and disadvantages cannot be simply evaluated through the formula. The brake pad formula is one of the core competitiveness of each manufacturer. Even if the same formula is used, the performance and service life of brake pads of different manufacturers will be different
