Recently, the German Saif (SAF) has introduced a new pneumatic disc brake, the P89 pneumatic disc brake. This air disc brake is not as heavy as a drum brake, and the production cost is not too high. . The P89 air disc brake has a powerful rotor that resists thermal deformation for up to 7 years of maintenance. The use of the new P89 air disc brakes will reduce maintenance costs compared to the use of drum brakes, and the upgrade of P89 air disc brakes will extend the maintenance cycle to 7 years.

Disc brakes have a shorter braking distance and a longer maintenance cycle than drum brakes. The P89 air disc brakes cost more than $1,500 to install on a trailer, but they cost less than drum brakes for later use. The P89 Plus is an upgraded configuration that includes a more powerful bimetal rotor that is effective against thermal distortions and a 7-year long maintenance cycle.
The precision bearing spacers of the SAF-P89 pneumatic disc brake are mounted between the inner and outer bearings to precisely control the maximum bearing life. Through a large number of product tests and long-term tests in Europe, it has been shown that the P89 upgraded bearing system can increase four times the bearing life. The SAF-P89 pneumatic disc brake will be put into production in July and soon the trailer equipped with the SAF-P89 pneumatic disc brakes will be seen driving on the road.
