Brake caliper pistons are either chrome-plated steel or phenolic plastic. Both of these are hollow to save weight. The phenolic pistons are excellent heat insulators and thus help prevent heat from degrading or boiling the brake fluid. Study Tips Feedback. Disk Brake Calipers Disc brakes are installed on the front of most passenger cars and are recognized as a better solution for the rear brakes as well.
Fixed and Floating Brake Calipers There are two brake calipers manufacturers install on automobiles and light trucks today. Floating Brake Calipers A floating caliper typically uses one piston to move the inboard pad into contact with the inner side of the rotor. Battery Special.

This is primarily a function of the number of pistons and the surface area of the brake pad where it actually contacts the rotor.
Obviously, a caliper with a greater clamping force is capable of slowing or stopping a vehicle easier and faster than a caliper that has a lower clamping force.
However, when the truck is customized with larger tires and heavy accessories, and when a substantial load of cargo is brought on board, these factory-installed calipers might not be powerful enough to provide the braking power the truck needs. Fortunately, there's a substantial aftermarket for truck calipers. From the manufacturer, a truck might have calipers that provide in the neighborhood of 5, square millimeters 7.
An aftermarket caliper can more than double that surface area, providing the clamping force required by a fully customized vehicle. More than most brake parts, truck brake calipers have to deal with a lot of heat. Heat is bad for brakes because it can lead to brake fade and reduced stopping distances.
Good ventilation in the caliper is essential for continuous, consistent brake performance. In addition, a larger brake rotor or brake disc surface can also help spread the heat over a larger area. Trucks and SUVs aren't the only vehicles that require special brake equipment; however, the calipers in these heavy-weight vehicles do have a difficult job to perform.
Some might even say that truck brake calipers should be considered high-performance brake calipers. In the next section we'll look at some of the features that high-performance brake calipers can offer other vehicles. Disc brakes were originally developed for race cars. Everyone knows that race cars move along at high speeds -- but they also need to decelerate rapidly. In the early days of racing, when most cars were equipped with drum brake systems, brake fade led to a number of on-track mishaps.
Disc brake systems were better ventilated, and as a result, reduced some of the stress that racing and excessive heat. In time, these powerful brakes trickled down to less performance-oriented vehicles.
Now, they're even found on most economy cars. Nonetheless, high-performance cars are still a major market for better and more powerful brakes, and variations on the basic brake caliper design help these brakes provide superior stopping power.
There are certain limitations to just how much the vehicle's brakes and its calipers can do to stop a vehicle; while they may be able to bring the wheels to a stop, it's up to the gripping power of the tires to do the rest, and improved brake parts can't help beyond a certain point.
However, there are several ways in which brake calipers can be and have been improved. Some common features found in performance brake calipers include:. All of these technologies can increase the braking power provided by a caliper.
For smaller cars that typically aren't driven at high speeds, this extra braking power isn't really necessary. However, the faster and more powerful a vehicle is, the more it will benefit from high-performance calipers.

Brake calipers are a vital part of your vehicle's braking system. Brake calipers squeeze the brake pads against the surface of the brake rotor to slow or stop the vehicle. Brake Caliper Tool " ". You may need a brake caliper tool to retract the caliper piston.
This will provide the clearance you'll need to install the new brake pads. Lisa F. Motorcycle Brake Calipers " ". Motorcycle brake calipers may be smaller than the brake calipers on other vehicles, but they provide plenty of stopping power for the relatively lightweight bikes. Truck Brake Calipers " ". Performance Brake Calipers " ".
High-performance cars need big, strong brake calipers that can slow or stop the vehicle from high speeds. Bigger pistons -- The larger the pistons are, and the greater the area over which they come in contact with the brake pads, the more clamping force they have on the rotor. More pistons -- Low-end floating brake calipers have a single piston, on the inboard side. Low-end fixed calipers have a single pair of pistons, flanking the rotor disc.
High-performance calipers can have multiple pins or pairs of pins, mounted on opposing sides of the rotor.
