Types of brake calipers

Motorcycle brake pliers

Motorcycles are smaller than cars, so they need less braking power. Nevertheless, in some ways, the ability of a motorcycle to slow down or stop is more important than other vehicles. You might ask that? Well, even small fender benders can be fatal because the driver is not basically protected. It is important to avoid accidents when riding a motorcycle. But what kind of brake pliers do motorcycles need?

The answer is relatively simple and light. Unlike larger calipers used in some cars and trucks, motorcycle brake callipers must be kept small to avoid overwhelming the bicycle and impeding cyclists. Motorcycle brake pliers are usually made of light materials (such as aluminum), and aluminum also has

It increases the advantage of rust prevention. Some motorcycles are bigger and more powerful than other motorcycles. Obviously, these bikes need more braking. A lot of smaller ones

The lower powered bikes still use drum brakes, but most large bikes now have disc brakes – especially on the front wheels. In order to increase the braking force, the calipers on the more powerful motorcycles usually have multiple pistons. Some have two or even to four pistons, while others may have up to twelve pistons in a single caliper. Most motorcycles actually have greater braking force than absolutely necessary due to their light weight – but as we mentioned earlier, it is not a bad idea when you are riding fast, unprotected vehicles.

On motorcycles, the front calipers are fixed to the front fork – the metal assembly holds the front wheels and suspension in place and supports the handlebars. Until recently, the calipers were fixed to the front fork with bolts extending at right angles to the rotor. In recent years, with the increasing popularity of radial disc brakes, a technology that has been used in racing cars, the calipers are fixed farther away from the fork by bolts parallel to the rotor surface. These radial mounted calipers reduce the vibration of the traditional calipers in the fork.

Because they are often more exposed than car calipers, and calipers may be the most noticeable of all motorcycle brake components. Therefore, the appearance of motorcycle calipers may be important for many riders. In fact, brake caliper paint can be obtained from the car store and can be used to customize the motorcycle brake caliper. Of course, the same paint can be used on car calipers. However, experts suggest that chromium should not be placed on the caliper. Chrome plating may be attractive but can cause the calipers to retain heat, resulting in unnecessary brake attenuation.

Truck brake caliper

Undeniable: trucks and SUVs are large – in some cases too large. With the increase of size, momentum increases. This means that trucks and SUVs need more braking than cars. So where can they get the brake force they need? Truck brake caliper. The brake force of the calipers depends on the clamping force – the force that the calipers can apply to the rotor surface. This depends mainly on the number of pistons and the surface area of the brake pads (where they actually contact the rotor). Obviously, the brake caliper with larger clamping force can make the vehicle slow down or stop faster than the brake caliper with lower clamping force.

Many trucks are shipped with basic floating calipers that provide sufficient clamping force to the vehicle when they are delivered to the dealer. However, if larger tires and heavier accessories are customized for the truck and a large number of cargo is put on board, the calipers installed in these factories may not be sufficient to provide the brake force required by the truck. Fortunately, there is a large after-sales market for calipers. In the view of the manufacturer, trucks may have calipers, which have a surface area of about 5000 square millimeters (7.8 square inches) between the piston and the rotor. The surface area of the after-sales callipers can be more than doubled to provide the clamping force required for fully customized vehicles.

Truck brake pliers are more than most brake parts, and they must bear a lot of heat. Heat is not good for the brake, because heat can cause the brake to decay and shorten the brake distance. Good ventilation of the calipers is essential for continuous, consistent braking performance. In addition, larger brake rotor (or disc) surfaces can also help spread heat to larger areas.

Trucks and off-road vehicles are not the only vehicles that require special braking equipment. However, the calipers of these heavy vehicles are indeed difficult to implement. It has even been said that truck brake tongs should be considered high performance.

High performance brake caliper

Disc brakes were originally developed for racing. Everyone knows that cars will drive at high speeds – but they also need to slow down quickly. In the early days of racing, most cars were equipped with drum brake system, which resulted in many track accidents. The disc brake system is well ventilated, thus reducing some of the pressure caused by racing and overheating

Accumulation can cause – which reduces (but cannot eliminate) brake attenuation. Over time, these powerful brakes gradually infiltrate into vehicles with weak performance. Now, they can even be found in most economic cars. Nevertheless, high performance vehicles remain the main market for better and stronger brakes, and the changes in the basic caliper design help these brakes provide excellent braking force.

There are some restrictions on how many brakes and their brake pliers can stop the vehicle. Although they may stop the wheels, the grip of the tires depends on the grip of the tires, and the improved brake components are not helpful. However, there are several ways to improve the brake callipers. Some of the common features of high performance brake caliper include:

Larger Pistons – the larger the pistons are, and the larger the area they contact the brake pads, the greater the clamping force they have on the rotor.

More pistons – the low end floating caliper has a piston on the inside. The low end fixed callipers have only one pair of pistons, located on both sides of the rotor disc. High performance calipers can have multiple pins or pairs of pins that are mounted on the opposite side of the rotor. Six piston model is more and more common, even twelve piston model is not unheard of. The increase in the number of pistons is also used to increase the clamping force of the calipers.

Less heat retention – in a sense, your brakes can be seen as devices that convert motion into heat. As the car slows down, all of these kinetic energy must flow to a certain place, and most of it is consumed in the form of heat. If you want to change the angle, all friction between the brake pad and the rotor will generate heat, just like a match produces heat. If too much heat is accumulated, the brake will begin to decay or fail. Therefore, the better the ventilation of the brake caliper, the better their performance. Similarly, the larger the surface of the brake rotor, the more heat is emitted.

As the surface of the rotor increases, the clamping force of the piston must be increased to prevent the brake from decay. If the caliper has more than one piston (or pairs of pistons), the surface of the brake piston is initially heated by the piston pushing towards the brake pad at the front edge of the caliper, which makes the rotor surface heat when it is rotated back to the piston. Therefore, if the piston is closer to the rear edge of the caliper, it can improve its performance. So differential caliper should use smaller piston in front and larger piston in rear.

All of these technologies can improve the braking power provided by the caliper. For small cars that are usually not running at high speed, this extra braking power is not really necessary. However, the faster the vehicle is, the more powerful it will benefit from high-performance calipers.
