In the development of current vehicle capabilities required an effective braking system, has a little wear, and
safety riding. The objective of the research is to determine wear and braking distance because of braking load and
speed motorcycle Honda supra X125 cc. This research used the speed of 50 km/h, 60 km/h, and 70 km/h. Braking load
used to be 4 kg, 5 kg, and 6 kg. The test was done by dynamic method and the research was done in two stages; testing
in the field and measuring brake wear in the lab using a profile projector. Testing the hardness of brake was done to
know hardness brake before and after testing due to the effect of wear, braking time, and braking distance.From testing
it was found that increasing of braking load, resulted in increasing wear. The smallest wear was 6 x 10-5 mm/sea at a
speed of 50 km/h, braking load of 4 kg, and braking time of 15.94 seconds. Increasing the speed resulted in increasing
braking distances with the smallest of braking distance was 55 meters at the breaking load of 6 kg, the speed of 50
km/h and braking time 9.93 seconds. The hardness of brake lining, increased after the brake lining wear testing. The
hardness before the test was 95.8 HRN and after the test was 100.4 HRN.
