A Detailed Guide About Semi-Metallic Vs. Ceramic Pads

Post date:



What are ceramic brake pads?

Ceramics pads are the most expensive among the options for replacement brake pads. The ceramic brake pads last the longest. Using ceramic materials mixed with copper fibers, these brake discs are stable over a wide range of temperatures and produce minor brake dust. 

They provide a firm brake pedal and are gentle on the brake system simultaneously.

The downside of ceramic brake pads, aside from their high cost, is that they don’t absorb heat well in extreme braking circumstances (this can cause excessive heat and wear to the rest of the brake system), and they don’t work as well in the cold. For a comfortable and quiet daily commute, ceramic brake pads are the best option (despite their high price).

What are Semi-Metallic brake pads?

Semi-metallic brake pads may be a better choice when you drive an extreme vehicle or if you have excessive driving habits. These metal pads are durable, heat resistant, and provide the most excellent stopping power because they are made with a high percentage of steel, iron, copper, and other metals. 

Moreover, they work well over a wide temperature range and absorb heat well, thus keeping brake systems cooler. In general, semi-metallic pads last longer than organic ones but not as long as ceramic ones, and they are more expensive than organic ones.

Between 30 and 70 percent of semi-metallic brake pads, also referred to as “metallic” brake pads, are made of metals like copper, iron, steel, or other composites. Graphite lubricant and other long-lasting filler materials are frequently added to finish the production process. Semi-metallic brake pads are suitable for a range of applications, including daily driving and racing.

Semi-metallic vs. ceramic brake pads

While it is true that nearly 30% of new auto manufacturers are now using ceramic brake pads, this should not mean that every vehicle should undergo a brake pad replacement. Ceramic and semi-metallic brake pads have some advantages, but there are also some drawbacks in each case.

First, you must understand how brake pads are constructed to understand their differences. Ceramic brake pads are usually composed of dense ceramic material with copper fibers. In contrast, semi-metallic brake pads are synthetic resins with embedded metal fibers (usually steel).

Comparison of brake dust

Sellers of ceramic brake pads often boast that their places produce less brake dust than semi-metallic pads. Ceramics indeed make less dust per unit time than semi-metallic brake pads. This is due to the friction mechanism: ceramic brake pads use adherent friction (think adhesive or sticky), while semi-metallic brake pads use abrasive friction (think sandpaper on wood). 

Comparison of durability and cost of brake pads

Ceramic pads are usually more expensive upfront than semi-metallic counterparts, requiring less frequent replacements. You may conclude that ceramic brake pads will cost less overall in the long run regarding the number of pads that will need to be purchased, but this is not accurate. 

There is a false reality in this calculation if you select brake pads that are not capable of performing within the required temperature range, whether ceramic or semi-metallic brake pads, you will encounter problems prematurely.  

Compared to semi-metallic brake pads, ceramic brake pads perform poorly at higher temperatures. 

Ceramic brake pads are prone to fading or overheating in more aggressive applications. In this case, the friction material will be transferred to the rotor in uneven deposits. People are all too familiar with the pulsation issues created by irregular deposits. 

Additionally, use a high-performance pad (usually an abrasive semi-metallic compound) but do not use the brake pads within the intended temperature range. You will also run into this problem. This makes it essential to know what combination of rotors and pads will work with your application and your use.  

To begin with, go with a brake pad compound designed for your car (what the manufacturer recommends). Based on your driving style and application, you will need to adjust what combination of rotors and pads to use.

Comparison of brake noise

Ceramic brake pad manufacturers also claim that brake noise will be reduced by installing ceramic brakes into your vehicle. As opposed to semi-metallic pads, the pad material vibrates at frequencies outside the normal range of human hearing. Several factors can indeed cause brake pad noise.  

Differences in performance

In general, ceramic brake pads perform well at a wide range of temperatures, ideal for daily use. Semi-metallic brake pads are recommended in sports vehicles, trucks, and fleet vehicles. For high performance, semi-metallic brake pads are better than other abrasive pads.

What Are The Best Brake Pads For Your Vehicle?

Choosing the best brake pads for your vehicle can be difficult as there are many factors to consider, such as driving conditions, vehicle make and model, and personal preferences. The best brake pads for your vehicle will depend on how you use your vehicle, with performance and durability being the most important factors to consider. For high-performance vehicles and those used for racing or heavy-duty towing, a high-performance brake pad with a high metal content, such as a semi-metallic brake pad, maybe the best choice. Ceramic brake pads offer a good balance between performance and quiet operation, with low dust production for daily driving. Ultimately, the best brake pads for your vehicle will be the ones that meet your specific needs and provide the performance and durability you require.

But when making a choice, one must keep in mind that brake pads are meant for other purposes and vehicles, just as all cars are made differently and have different features. Thorough research is therefore necessary before making a decision.

It is vital to understand how brake pads work and their functions. Moreover, it is equally important to know what brake pad material will be most suitable for your automobile/driving purpose.

In doing your research on this topic, you will quickly realize that one cannot be considered the best brake pad. However, you can choose the brake pad that is most suitable for you.

You will not be disappointed with Ceramic pads, for instance, if you are looking forward to a comfortable driving experience. If, however, you drive a sports car or expect a soulful performance from your vehicle, you should consider a semi-metallic brake pad.
