 What's the slack adjuster for semi trailer and truck ?

 

In order to ensure sufficient braking force, most of heavy duty trucks and trailers use pneumatic braking system. Because pneumatic braking system can provide more powerful braking force than hydraulic braking. But the same as hydraulic braking, pneumatic braking must also ensure that there is a proper gap between the brake lining and the brake drum in order to exert normal braking force.

Slack adjuster (1)

In an air brake system, the gap between the brake drum and the brake lining is not unchanging. Because the brake lining is a consumable, it will gradually become thinner as it continues to wear and consume, causing the gap between the brake drum and the brake lining to become larger and larger. As the gap increases, the braking force of the truck will be weakened. Therefore, it is necessary to ensure that the gap between the brake lining and the brake drum is within an appropriate range. Too small will cause brake drag, and too large a brake. The motivation is not enough.

The device responsible for adjusting the gap is the Slack adjuster. There are two main types, the most common is the manual Slack adjuster, but now many trucks have begun to use the automatic Slack adjuster.

The manual Slack adjuster is the adjustment arm that manually adjusts the brake gap. It is currently the most commonly used Slack adjuster. It has the advantages of low price and simple maintenance, but it also has some disadvantages. Because the brake gap is controlled by the hand-adjusted arm, and the operation is entirely based on human experience, relatively large errors are prone to occur, which seriously affects driving safety. It also requires the operator to lay under the car to adjust, which is very troublesome.

Advantages of automatic adjustment arm:

 

First, the braking force is stable:

The automatic slack adjuster will not be like the manual adjustment arm. The braking force will be lower and lower after the adjustment . The braking force of the automatic adjustment arm is very stable, because it can control the braking gap within the optimal range at any time, which is safer than the manual slack adjuster.

Second, easy to maintain:

The automatic adjustment arm does not require you to frequently lay down under the narrow car to adjust the brake pads.

 

Third, suitable for ABS:

The automatic slack adjuster is more suitable for use on trucks equipped with the ABS system than the manual adjustment arm, and can maximize the advantages of the ABS system.
