If you are in the position to choose which brake pads to mount on your vehicle, you should know that you will find several types in the market.
When we are about to close the purchase of our future vehicle. I think we can count on our hands the number of people who notice what the brake system that equips your car is. It may seem like a trivial matter, but if we are not aware of what is causing our vehicle to slow down, we can be disgusted on a couple of occasions. During an emergency braking or when we go to the workshop to replace some part of the system braking.
Disc brakes and drum brakes
First of all, we have to be clear that two braking systems can find in a vehicle. Starting with the most rudimentary, we will find the drum brakes, increasingly in disuse because in new vehicles it is difficult today to find them except in the lower ranges. This type of brakes began to lose prominence as the power of the vehicles increased so that the need for even more effective braking became imperative.
The drum brakes fulfilled their mission until they were no longer necessary. It not only for their braking capacity against disc brakes but also for other qualities that relegated them against the previous ones. The poor ability to dissipate heat generated in the braking. Also, the low capacity to eliminate the water or the humidity of its interior, which could lead to scares when being reduced its capacity to realize incorrect braking conditions.
The simplest is the solid discs that we will normally find in smaller and lighter vehicles. In an intermediate step and as a more used measure are the ventilated brake discs. They are not more than two discs joined with die-cut in its body to improve its cooling. While in an upper step, we will find an evolution of the previous ones that have another type of die-cut. It also serves to channel the air and that we will find mounted on high-performance vehicles as the king of all carbon-ceramics is found. It intended for large sports due to its components, lightness, and braking capacity.
Types of brake pads
As you know, disc brakes make use of pads that brake our vehicle and can make different compounds. These pads mounted on another component of the braking system called calipers. They press the pads against the disc using their pistons when we step on the brake pedal to stop the vehicle. These pills with the passing of the kilometers will lose thickness, so sooner or later, we will have the time to go to our workshop to replace them.
Normally in the workshop, you go to, they will reinstall the pads marked by the manufacturer. But if you are to choose it on your own or want to know what it is that you are installing, you should know that you can find various types of brake pads in the market. Which will vary in their characteristics depending on the type of vehicle and our driving:
- Semi-metallic brake pads: These pads characterized by containing around 30% and 65% steel wool, copper, or iron powder mixed with inorganic fillers. With these pads, you will gain in duration and will perform an efficient heat transfer. It will be especially efficient in aggressive conductions, or that requires a great effort, especially when it heats up, but they will be inefficient in cold conditions.
- Organic brake pads: These brake pads are manufactured by mixing components such as glass fibers, rubber, Kevlar, and carbon. Thanks to these pads, we will ensure effective braking in virtually any situation. In addition to being the quietest, but they have faster wear and create more dirt on the tires, and, also, they can melt into very aggressive or extreme driving.
- NAO brake pads: They are very similar to the previous ones, but differ by the incorporation of a small amount of metal, between 10% and 30%, thus improving braking and heat dissipation. Logically, having this amount to older metal, they will be louder and also generate more dirt on the tires.
- Ceramic brake pads: thanks to ceramic fibers, bonding agents, non-ferrous materials, and very small amounts of metal. These pickups will sound like high-performance vehicles, the use in them is no coincidence, and they allow very effective and superior braking compared to the previous ones. As well as being quieter and cleaner, but as you can imagine, they are the ones that most cost will be for our pocket.
