Bendix goes beyond dynamometer testing

To ensure both safety and reliability and meet the demands of vehicle manufacturers’ original equipment requirements, braking technology expert Bendix goes well above and beyond dynamometer testing.

Bendix laboratory engineers constantly test friction characteristics, durability, effects of brake pads on the life of rotors, dimensional stability, reactions to extreme cold and heat plus noise – both audible and inaudible to the human ear.

As a major supplier to local and international car and truck manufacturers and the aftermarket, these comprehensive evaluations and designed to meet and exceed government and OE customers’ requirements on an on-going basis, Bendix announced.

“Experimental and current friction material testing is both ongoing and rigorous with dynamometer testing includes the effectiveness of the material, wear evaluation, torque and pressure control, temperature with extended burnish, compressibility and temperature extremes,” according to a recent press release. “This is followed with road and racetrack testing covering aspects such as high speed fade, driver assessment, judder assessment, delaminating, rear wheel brake lock up, city and county driving conditions, graunch noise, drum drag and general performance.”

The brake system development dynamometer testing engineering standard establishes a procedure for testing passenger vehicle, light commercial and light off-road vehicle braking to determine temperature – outer pad, inner pad and rotor, deceleration, line pressure, dynamometer speed, fluid displacement, stopping distance, brake application time and cooling air velocity. Friction material and disc thicknesses are measured and carefully monitored against established protocols and the test history is plotted.

The vehicle noise test procedure for testing the brake system of passenger vehicles, light commercial and light off-road vehicles is designed to establish the propensity for the brake system including suspension, calliper, rotor, knuckle and friction material to generate noise.

Road tests are conducted under full load conditions as well as unloaded with just the technician on-board and all components must meet stringent parameters.

“These exhaustive tests not only ensure safety and reliability for the motorists but provide a high degree of confidence and trust for the mechanic who fits this world renowned brand of brake components,” according to Bendix.
