Investigation and Resolution of Vehicle Brake Judder 2020-01-1609
One of the major discomforts while driving any medium to heavy commercial vehicle is brake judder. Brake juddering can be defined as vibrations felt on steering wheel or brake pedal or cabin floor, when brakes are applied at certain speeds and pressures. The frequencies of this judder lie as high as 500 Hz to as low as 10Hz. The brake juddering can be caused by a number of factors because of which providing universal solution only from brakes point of view is difficult. Some of the causes are related to part fitment, part quality, material selection, manufacturing process, Design consideration, environmental factors, peripheral aggregates etc.
This paper gives us a brief idea about resolution of juddering problem in intermediate commercial vehicle by DOE method, and this methodology can be applied in heavy commercial vehicles also. This paper gives reader an insight about step by step root cause analysis of brake juddering on actual vehicle and an approach in resolving the juddering problem.
