What are the reasons for the soft brakes of a truck? How often should truck brake fluid be changed?

A truck is an indispensable means of transport for goods. However, some friends often feel the brakes are soft when driving a truck. What are the reasons for the soft brakes of the truck? How often should truck brake fluid be changed? Let's take a look at these questions together!

What are the reasons for the soft brakes of a truck?

1. The brake oil pipe on the truck is inhaled. It is necessary to know that the brake oil is the medium transmitted by the brake system. If air enters the hose, the brake fluid will be insufficient under high pressure, resulting in significantly less braking power. Therefore, we need to exhaust the braking system in time.

2. The quality of the brake fluid used by the truck is poor, resulting in a low boiling point, so there will be bubbles when braking. Once the bubbles appear, the truck brakes will become very soft.

3. The sub-pump or master cylinder on the truck is faulty. Once there is a problem with one of these two parts, it cannot guarantee sufficient oil pressure. Once the oil pressure is unstable, the brakes of the truck will become soft.

How often should truck brake fluid be changed?

The brake fluid of the truck needs to be replaced every 20,000 kilometers or 2 years of continuous use. For things like brake oil, it must be replaced on time. If it is not replaced in time, it will cause the brake oil to be cloudy, the boiling point will drop, the effect will be worse, and the brake will fail.

Because the brake oil system will always wear and tear, and at the same time, the brake oil will absorb the moisture in the air, causing oxidation and deterioration, which will easily lead to the deterioration and expiration of the brake oil, and the use effect will become worse.
