Types of Airplane Brakes for Small Planes
When it comes to aircraft brakes, kit plane builders can choose from a number of different options. From single or dual brakes to floating disc brakes, each type of aircraft braking system is slightly different in terms of installation, price tag, and performance. The first step to choosing the right airplane brakes for your kit build is to understand the nuances of each option.
Single Disc
Single disc brakes use just one disc, which rotates in unison with the wheel. When the pilot engages the brakes, brake pads press against both sides of the brake disc, slowing the rotation of both the disc and the wheel.
Single disc brakes are quite simple, with fewer parts than other types of aircraft disc brakes. This type of aircraft braking system is sufficient for many light, small aircraft.
Dual Disc
Dual disc brakes use a pair of discs to generate more braking friction compared to single aircraft disc brakes. The two discs are connected by a center carrier.
Dual disc braking systems are usually more expensive than single disc systems. However, two discs translates aircraft disc brakes to more braking power, so the higher price tag does come with increased performance.
Floating Disc Brakes
The brake disc in a floating disc braking system “floats” between pucks located on the inside and outside of the brake caliper. When the pilot engages the airplane’s brakes, the pucks move together, pressing brake pads to both sides of the disc and applying even friction and heat. This slows the rotation of the airplane’s wheels.
One attractive feature of floating disc brakes is easier installation. Because the brake disc “floats,” there is no exact right position required for proper installation and function. This is attractive to builders who are new to kit planes or simply prefer an easier installation.
The Importance of Choosing the Right Aircraft Brake
Choosing the right aircraft braking system depends on everything from budget and skillset to available real estate inside the plane. For example, a single floating disc system has a low parts count and is simple to install, which may be attractive to many kit builders. However, these systems take up more space in the aircraft than others, which may be limiting. A dual floating disc system delivers more stopping ability in a smaller package, a tremendous advantage when space is limited, but the installation process is more involved.
Here are some of the critical factors to consider when choosing an aircraft braking system:
Safety
Of course, basic safety is the primary concern when choosing airplane brakes. It is critical to choose an aircraft braking system that provides enough braking friction to reliably stop the airplane. This extends beyond general taxiing and routine takeoffs and landings. Aircraft braking systems must be able to reliably stop the aircraft in the event of a rejected takeoff or other emergency situation. Choosing quality aircraft brakes that meet applicable regulations and have a proven track record of reliable performance is a top priority.
Performance
Beyond basic safety requirements, the performance specs of airplane brakes can vary. For example, a dual disc system offers double the stopping power, which may be important to some pilots due to personal preference or intended service environment. Determining your priorities and desires regarding brake performance is key to choosing the right airplane brakes for you.
Durability
Aircraft brakes experience tremendous amounts of heat and friction while in service, especially when decelerating from high speeds during landing. Harsh operating conditions, including frequent takeoffs and landings or short runway use, can put additional stress and wear on these systems. While regular maintenance and component replacement are expected due to the demanding nature of aircraft braking, choosing a braking system with durable materials may extend the service life of key components.
Builder Skills
As previously mentioned, some types of airplane brakes are easier to install than others. Kit builders should factor their own skills into their purchasing decisions and determine whether they can install the brakes themselves or will need to request or hire help.
