As the top Michigan semi truck repair service, our team at Best Choice Tire and Service knows all about the complex braking systems semi trucks and trailers use. More importantly, we know how to keep your brakes operating at their optimal potential to keep you safe and minimize repair costs.
Today, heavy duty semi trucks use air brakes as their primary braking system. These were designed specifically for applications that require a lot of stopping power and are generally very reliable. Commonly, “S-cam” brakes, in which the mechanism used to push the shoes against the drums is S-shaped, are used. Less often, wedge and disc brakes may be utilized.
The air brake system uses pressurized air rather than a hydraulic-like brake fluid as seen in most cars and light duty pickup trucks. Because of this, air brakes rely entirely on air pressure to operate properly. If your truck or trailer is not braking normally, a loss of air pressure is a very likely cause.
Additionally, all trucks with air brakes manufactured after March 1, 1998 feature anti-lock braking systems to assist with hard braking. If your truck’s brakes seize up during a hard stop, it’s likely that the ABS system needs immediate repair.
Keeping your brakes operating correctly extends the life of tires and suspension components, as well as keeps you safer on the road. To schedule a repair or maintenance service with one of our expert mechanics, call us today at (810) 875-0593!
