How can I order BERINGER parts ?
->You can order directly from our distributors and Service Centers
->Call us or send an e-mail to firstname.lastname@example.org at any time and we will return some ideas.
I have a technical question. Who can help ?
->Our Service Centers are able to answer many technical questions, but for a precise technical or engineering question, please contact BERINGER directly.
Why are most BERINGER wheels made for tubeless tires?
->Tubeless has many advantages compared to tube type:
- safer (less risk of puncture)
- weight saving (a tube weights around 1 to 2 lbs)
- cost effective (no tube means no tube to buy)
These are the same reasons why nowadays you find tubeless wheels on cars, motorcycles, and all commercial airplanes. Tubeless designs have specific design to be airtight (most designs use o-rings) and precise machining to ensure proper contact between tire and wheel.
How can I choose the correct wheels, tires and brakes?
1. First, select your tires according to your use: What kinds of runways: grass, concrete, unimproved?
2. Match the wheel to the tires. (See our tire-wheel application chart in the catalog.)
The brakes you need will depend mostly on the weight of the aircraft and the landing speed, though tire size can come into play at the extremes of the size ranges: to get close, use the formula to calculate the Kinetic energy needed (see the catalogue page 9). Many popular setups are already listed in the kit list of the catalogue.
How do I know the type of brake fluid to fill my brake system ?
->The type of brake fluid to use is most of the time written directly on the brake caliper and on master
cylinders. DOT4 usually has yellow to amber color and MINERAL (“Mil spec” or “aviation”) brake fluid is
red. If you have any doubt please contact BERINGER.
I filled my brake system with the wrong brake fluid what can I do ?
-> The wrong brake fluid will damage the seals after only few minutes of contact. This is potentially dangerous because after a short period your brakes can lock or leak or stop working properly. If you have put the wrong fluid into the system, you will have to change all the seals of the entire system. (Note: this is true, regardless which brand of brake parts you use.) If you have a BERINGER system, ask BERINGER for repair kits or send the parts back to BERINGER service for repair.
If I switch to BERINGER Wheels &Brakes do I also need to change my master cylinders ?
-> If they are compatible with the brake fluid then you still need to check the hydraulic ratio: with our brakes we recommend using master cylinders with a piston bore of 1/2" (9/16” maximum). If the bore of the master cylinders is too big, they cannot produce enough pressure to provide enough braking torque on the wheels. Some master cylinders are so crude (or just so old) that the inherent smoothness and feel of BERINGER calipers can be masked in operation; for this reason, we recommend using only BERINGER master cylinders.
I want to improve my Wheel &Brake system but BERINGER prices are too high.
-> BERINGER systems are a little more expensive than ordinary products but thanks to their exceptional reliability and life, the operating cost is much more economical. It is often possible to pay back your investment in 1 or 2 years, with brake components that last, lines that don’t leak, pads that have 3-5 times the life of legacy pads, quicker and simpler pad replacements, no tube expenses, no bearing maintenance, and (with ALIR), fewer flat-spotted tires and straighter, shorter stops. And all that time, you are enjoying better, smoother braking.(And BERINGER wheels save weight and look good, too.)
