How about starting it.


Hayes has been developing industry leading braking systems for nearly 20 years. In 1997, we changed the face of mountain biking forever with the first viable hydraulic braking system—the Hayes Mag. The Mag was a good start and has continued to set the design standard for most brake offerings today.

Since that first brake, Hayes has continuously refined our product based on the performance demands of riders and the need for reliability and serviceability. We know that a design has achieved perfection not when there is nothing left to add, but when there is nothing left to take away.

Reinventing through research, development and testing.

The right brake for your application is the brake that’s been proven to perform. At Hayes Disc Brake, we’re meticulous about research, development and testingit’s what has earned us a reputation in this industry: When the CAD work is complete, our engineers begin simulation work on our products. FEA software is used to analyze the stress and heat impact to our designs.

Our R&D department employs the latest technology and software to analyze the noise and vibration characteristics of our systems. And throughout the various stages of development, our expansive machine shop lets us turn designs into completely functional prototypes.

Whether it’s testing prototypes or auditing production brakes, we have a wide array of equipment to ensure our systems perform. Dynamometers are used to analyze our brake systems and evaluate both rotor and brake pad performance. It doesn’t stop at performance. Our dynamometers are capable of simulating wet and muddy trail conditions, and provide us with an accurate measure of pressure, force, temperature, speed and torque.

The R&D lab is also outfitted with an electro-dynamic shaker for simulating the bumps, rocks, roots and drops on a trail. To ensure product performance and reliability, each brake system we design completes a countless amount of life cycle testing. These tests utilize the latest in PLC technology and sensors to control, monitor, and record system performance. On any given test, we may monitor brake pressure, clamp force or input force. We also complete a large amount of environmental cycle testing in three, large, PLC-controlled environmental chambers with temperature ranges from -40°F to 350°F.

Outside of the R&D lab, Hayes has a fleet of hard tolls and M suspension bikes at our disposal for field testing. Portable data acquisition units and sensors track “real life” conditions. We also have pro racers and riders from around the world riding our products and providing feedback. From South America to Europe to B.C., we are hooked up with some of the best riders in the world.
