What does front ventilated disc/rear disc mean?

[Desiree]

Ventilated disc, simply put, is a type of automotive disc brake. The ventilated disc plays a crucial role in vehicles. Below is the relevant information: 1. Definition of ventilated disc: As the name suggests, the ventilated disc has a ventilation effect, which means that the centrifugal force generated during professional use can create air convection, achieving heat dissipation. This is determined by the special structure of the disc. From the surface, there are many holes leading to the center on the circumference. These holes are manufactured through a special process, which is why the heat dissipation effect is much better than that of ordinary discs. Due to manufacturing processes and cost considerations, front ventilated discs and rear ordinary discs are commonly used in mid-range and entry-level cars. 2. Types of automotive disc brakes: There are two types of automotive disc brakes: solid disc brakes and ventilated disc brakes. The braking principle is the same, but the manufacturing process and braking effects are different.
