A study of physical disc brake effected to braking distance

Abstract

A disc brake is one of important auto parts for motorbike cycle industry which effected directly to life safety. As the result, this project aims to test the performance of the disc brake in order to study the physical disc brake that effects to braking distance and to be an alternative for testing the brake disc. The braking performance tester was designed and created in the single dynamometer which was not over 10 Hp and the 17of inertia .70 kg. m. Referring to testing state of JASO T204:2001 standard, this tester focused on testing the 3 different types of disc brake i.e. normal type, grooving type, and perforated type. The tested temperature was at normal state of the brake disc temperature (60° C - 80° C) and at high state (more than 100° C). The braking force from 9.81 N to 34.33 N at master cylinder was tested. moments was not over 92 The result revealed that at normal temperature, the braking performance of the three disc brakes (normal type, grooving type, and perforated type) was at 17.76, 21.80 and 19.00 per 1 mrespectively. However, the brake performance at high temperature was at 14.41, 18.06 and 18.93 per 1 m. This meant that the most efficient disc brake at normal temperature was grooving type of disc brake which was 22.74% different from normal type of disc brake. Nevertheless; the perforated type of disc brake was the most performance disc brake at high temperature which was different from normal type of disc brake at 25.32% 2 of contact surface areas 2 of contact surface areas respectively2m/s2m/s
