“…The brake distances from each test speed from the dry surface were shown in Table 2 including results from other works of literature. The underbone motorcycles were tested by Ariffin et al (2017) and this study, while high-performance motorcycles were tested by Dinges and Hoover (2018), Dunn et al (2012) and Green (2006). When compared between the underbone and the high-performance motorcycles, it was clear that the high-performance motorcycles achieved higher decelerations.…”

“…Green (2006) compared the stopping distance performance among total six motorcycles which were equipped with conventional brake systems, combined brake systems (CBS) and anti-lock brake systems (ABS) at some specific speeds. Ariffin et al (2017) compared the braking performance of common motorcycles in the Malaysia market under emergencies. The results from these studies are still not enough to construct the recommended safe stopping distance for a motorcycle which covers all speed range.…”

Rear-end collision is one of the top accidents for the motorcycle in ASEAN countries because the motorcyclists always keep their following distances too short. There are no specific safe distances suggested for motorcycle especially in an emergency braking situation. This study proposed a model based on the piecewise linear model of motorcycle braking deceleration profile and kinematic equations for calculating the stopping distances in a worst-case scenario. The calculated results were compared to the braking experiment and test results from other studies. The information from this study can be useful to relevant authorities such as driving institutes and enforcement agencies in order to setup a safety measure for the motorcyclists.

“…A study shows that by using drum brake systems on both wheels, the stopping distance of Honda EX5 is 14.31 m for riders without passengers. Similarly, Yamaha LC that uses disc brakes as the braking system has 13.36 m stopping distance for the same conditions [27]. Braking distance is closely related to braking time.…”

“…Stopping distance is the distance required for a vehicle to from starting braking until it completely stops. Stopping distance depends on several factors: vehicle characteristics (drag coefficient, vehicle weight), speed, and road conditions [26] and the type of brake and vehicle [27]. The stopping distance is directly proportional to the braking time.…”

Experimental study of the effect of brake drum cooling grooves on motorcycle braking performance

et al. 2022

Some important indicators in the braking system performance on a motorcycle are the braking temperature and stopping distance. High temperatures due to frictional heat in the drum brake can decrease the braking force and cause a slip. To improve braking performance, an effective strategy is needed to reduce the drum temperature and shorten the stopping distance. This study aims to analyze the effect of cooling grooves on the standard brake drum to decrease the drum brake temperature and the length of stopping distance. The measurements were compared to the standard drum brake as a reference, and two types of the modified ones to increase the braking performance by adding the slant-grooved and a straight grooved on brake drum. Braking is performed by providing a compressive load of two kg on the brake pedal for three cases of motorbike speed: 20, 40, and 60 km/hour. The results show that the brake drum with straight cooling grooves provides better braking performance compared to other drum brakes. For a speed of 60 km/h, the temperature of the straight grooved brake is 3.5 ºC. The stopping distance is 29.1 % shorter compared to the standard one. It shows that adding cooling grooves on drum brake can increase the effectiveness of motorcycle braking performance at various speeds. The results show that the brake drum with straight cooling grooves provides better braking performance compared to other drum brakes

“…To the best of the author's knowledge, only a few references in the literature examined the braking performance of Malaysian riders. Ariffin et al [11] conducted braking test at the dry path with the speed of 50 km/h using different low cc motorcycles. It was found that the highest deceleration of 0.85g was achieved using both front and rear brakes on the motorcycle equipped with a disc and drum.…”

The complexity of motorcycle braking systems remains in the different applications of brakes using both hands and legs. In comparison to passenger vehicle systems that use brake pedals to slow down, motorcycles usually have independent front and rear braking. Furthermore, motorcycles have a high center of mass with a short wheelbase. This may result in loss of control during harsh braking. Thus, the motorcyclist's braking technique is important in producing safe braking. The objective of this project is to understand the difference between the braking technique of people who have attended defensive riding training (trained) with those people who did not attend (untrained). Both trained and untrained riders used higher rear braking force than front braking force at all test speeds. The trained riders improved the front braking force by 26.8% and reduced the rear braking force by 18.2% when the test speed changed from 30 km/h to 50 km/h. Thus, the deceleration produced by trained riders linearly increased with the increment of speed. On the other hand, untrained riders improved front and rear braking force by 15.6% and 3.4% respectively from 30 km/h to 40km/h. No change in braking force was found when the speed increased from 40 to 50 km/h, thus producing similar deceleration at both speeds respectively. This may increase the risk to the rider because, at higher speeds, the motorcycle produces a higher braking distance and time if a similar force is applied. Further analysis shows that trained riders used deceleration in the range of 0.40-0.49 at the speed of 30 km/h, and adjusted the motorcycle deceleration to 0.60-0.69 at the test speed of 40 and 50 km/h. Nevertheless, the untrained riders produced deceleration in the range of 0.5-0.59 in all test speeds.
