KOBE –
Another severe accident has occurred on a steep, extended downhill stretch of Prefectural Route 95 in Kobe, the place authorities have repeatedly warned drivers concerning the threat of brake fade, a probably harmful lack of braking energy that may have an effect on unusual passenger vehicles in addition to massive vehicles.
The newest accident occurred on an extended downhill part close to Kobe University, the place a tow truck pulling a big truck crashed right into a utility pole.
The highway descends steeply over an prolonged distance. Viewed from the facet, the elevation drops by about 100 meters between two factors alongside the route.
The similar part has been the scene of repeated accidents. In 2019, 9 folks had been killed or injured in a crash on the prefectural highway.
Following that accident, native police distributed security warnings and maps urging drivers to train warning. The highway was additionally designated as a precedence route for measures towards brake fade.
Brake fade happens when repeated use of the foot brake, notably whereas descending an extended slope, causes parts concerned in braking to turn into extraordinarily scorching. As temperatures rise, the brakes can progressively lose effectiveness.
The phenomenon will not be restricted to massive vehicles and buses and may happen in passenger autos.
Brake fade has beforehand been blamed for deadly accidents in Japan. In 2022, a big chartered bus overturned in Shizuoka Prefecture after its brakes misplaced effectiveness. The bus failed to barter a curve, crashed and overturned, killing one particular person.
Brake fade can develop after steady use of the foot brake over solely a number of hundred meters, which means it could actually happen even on comparatively quick downhill stretches.
High summer time temperatures might additional improve the chance. Because brake fade is attributable to extreme warmth within the braking system, excessive out of doors temperatures could make it harder for the brakes to dissipate warmth.
Drivers are suggested to rely extra closely on engine braking whereas descending steep slopes somewhat than repeatedly making use of the foot brake. This may be performed by shifting from drive right into a decrease gear, similar to second or low, relying on the automobile.
If brake fade happens, drivers ought to progressively shift down via the gears, shifting from drive to second after which to low because the automobile slows. Once the pace has fallen sufficiently, the parking brake may be utilized to assist convey the automobile to a cease.
Drivers mustn’t shift immediately into park whereas the automobile continues to be shifting in an try and cease it. Doing so can injury the transmission and eradicate the flexibility to make use of engine braking, additional lowering the motive force’s potential to sluggish the automobile safely.
