Everything You Need to Know About Brake Discs Used in Commercial Vehicles

Published by:

Brake discs differ between passenger-driven vehicles and commercial vehicles. Take, for instance, their lifespan. Because commercial vehicles usually carry heavier loads and spend more time on the road, the use of brake discs is more intense. You can also expect frequent brake repairs. In short, commercial brake discs have a shorter lifespan than their counterparts.

Nonetheless, brake discs used in commercial vehicles can still be utilized to their full potential. To do so, they must meet a certain set of criteria. And they are as follows:

• Reduced judder and wear: The materials used in the rotors must be stronger. They should be resistant to friction, heat, and wear. These are parts that you do not usually see in lightweight or passenger vehicles. This is because they are both much heavier and bigger than the standard brake disc model. This characteristic criterion for brake discs used in commercial vehicles also ensures low tolerance levels.

• Withstands heat: Technology has contributed a lot to make use of specialized materials for the manufacture of these parts. These specialized materials can disperse friction-induced heat more uniformly and much easier. Under high pressures, uniform dispersion ensures that the shape and surface will not crack or deform.

• Works well under force: As stated, most commercial vehicles are used to carry very heavy loads. Drivers have a harder time stopping them because of their higher momentum. Thus, brake discs should be enhanced accordingly. They should be strong enough to slow down the vehicle while making sure that no breaking or cracking happens from the intense weight.

• Uniform wear: The root cause of uneven wear is many. Perhaps another component is not even or the car may be overloading. When it comes to vehicles, they are expected only to withstand standard weights. Going over the limit could lead to uneven brake disc wear and engine overload. Though discs can be skimmed, it is a practice that can decrease the quality and function of the material.

Now that you know the things that make brake discs fitting for commercial vehicle use, you should also know when these discs become problematic. Problematic discs are not so hard to notice. Below is a list of descriptions of the most common brake disc problems to help you better spot them.

• Blue discs: Discs turn blue when they suffer from high temperatures. Very high temperatures are often caused by constant brake use and heavy stopping. Make sure to check the caliper in case the problem is found there.
• Heat checking: Heat and cold create a pattern that is akin to stretch marks when the discs are put under intense levels of pressure. They also appear when rapid cooling takes place.
• Spots and cracks: If your discs look uneven and patchy, they are caused by excessive heating. You can avoid this by properly applying your brakes minus the sudden stopping.

Safe braking can only be assured if you make it a habit to regularly check your brake discs. Because commercial vehicles are put under a lot of pressure and use, they should be properly maintained and regularly checked. Always remember that more time spent on the road can affect the quality of engine parts and components.
