The brakes must be strong enough to stop the vehicle within a minimum distance in an emergency. The driver must have proper control over the vehicle during emergency braking and vehicle must not skid. The brakes must have good antedate characteristics their effectiveness should not decrease with prolonged application and thus it demand that the cooling of the brakes should be very efficient. Fo...

Driven by the desire for safety and automobile regulations, there has been a movement from the drum brake system, where braking force is not as predictable, to the disc brake system that still continues to this day. This shift is perhaps most noticeable in the heavy vehicle industry. However, despite the improvements in stopping distance, the open nature of the disc brake system makes it more p...

Just, Fabian M.S.E.C.E., Purdue University, December 2013. A Strategy for Minimizing Parkinsonian Noise from a Joystick Controlled Wheeled Mobile Robot . Major Professor: Raymond A. DeCarlo. This thesis investigates movement of an electric wheelchair as a wheeled mobile robot (WMR) with a battery rechargeable through regenerative braking.The WMR has two wheels, each of which can propel or brake...

Worldwide, both brake lamps and tail lamps on motor vehicles are required to be red. Previous studies have not examined the effect of this confound in a complex, high-traffic scenario in a driving simulator or on visuomotor behavior. In the first experiment, drivers detected brake lamps on nine lead vehicles and lane changes on two rear vehicles in a 15 min simulated night time highway drive. A...

Objective: To reanalyse data on the lung content of asbestos fibres among brake mechanics. Methods: I re-analysed data published by Butnor, Roggli and colleagues on the lung content of chrysotile and tremolite asbestos fibres among brake mechanics and controls. Statistics of the distributions were estimated by maximum likelihood to accommodate observations below the detection limit. Mean concen...

Intensive mass and chemical measurements were performed at roadside locations in Reno, Nevada, and Durham/ Research Triangle Park), North Carolina to derive tailpipe, resuspended road dust, and brake-wear emission factors from in-use vehicles. Continuous particulate matter (PM) data were utilized to derive total emission factors while integrated PM data were used to attribute the calculated emi...

Calcium (Cav1 and Cav2) and sodium channels possess homologous CaM-binding motifs, known as IQ motifs in their C termini, which associate with calmodulin (CaM), a universal calcium sensor. Cav3 T-type channels, which serve as pacemakers of the mammalian brain and heart, lack a C-terminal IQ motif. We illustrate that T-type channels associate with CaM using co-immunoprecipitation experiments and...

The main sources of non-exhaust vehicular emissions that contribute to road dust are tire, brake and clutch wear, road surface wear, and other vehicle and road component degradation. This study is an attempt to identify and investigate heavy metals in urban and motorway road dusts as well as in dust from brake linings and tires. Road dust was collected from sections of the A-4 motorway in Polan...

In 1999, National Highway Traffic Safety Administration (NHTSA) researchers theorized that substantial improvements could be made in the braking performance of medium and heavy trucks. Therefore, NHTSA initiated a multi-year research program to learn what improvements in stopping performance could be achieved using advanced, but currently available, brake technology for medium and heavy trucks....
