In this issue, brake pad manufacturers will introduce several common types of brake pad formulas on the market. We hope they can be helpful to you. If you are interested, let's take a look together!

The world is divided into three formula systems. One type is a low metal formula, which is like that of Mercedes Benz and BMW, with high friction coefficient, short lifespan, fast grinding discs, but ultra sensitive brakes; One type is a relatively common semi metal formula, which has strong universality, represented by the original American cars. The friction coefficient is moderate, and the normal service life can reach 30000 to 70000 kilometers, with less ash falling and low wear on the disc. The last type is ceramic formula, which is characterized by outstanding high-temperature braking ability. Under high temperature conditions such as continuous emergency braking and downhill braking at high mountains, its friction coefficient remains stable, while it does not fall off dust, has a long lifespan, and has almost zero wear on the disc. Ceramic formulas have also become the mainstream of later market development due to their environmental characteristics. As for many high carbon formulas, carbon fiber formulas, etc. on the market now, they should all be defined by manufacturers themselves.

Which of the three formulas is better?

Answer: In terms of the performance indicator of safe braking of brake pads, all three formulas are good and can be used. Considering safety, social development direction, economy, and environmental protection, ceramics are superior to semi metals and semi metals are superior to low metals.

How to identify these three formulas?

Answer: Semi metal, as the name suggests, contains nearly half of the metal fibers. You will see a lot of metal fibers on the surface, which seems very hard; Low metals contain less metal fibers, and most have large black graphite particles or other large fillers, resulting in a relatively coarse structure; The ceramic formula has a delicate structure and is generally subjected to high-temperature ablation, with a layer of carbonization on the surface. There are many fine cracks on the side of the friction material.
