Abstract
Excellent control of braking system in automobile is the essential for safety of braking
performance. The brake disc is affected by type of friction material of brake pad. The
determination of mechanical interaction that happen between brake disc of automobile and brake
pads are very important in design consideration of braking system of automobiles.
For this investigation, the TOYOTA HIACE minibus taxi of 12 seats that used in Ethiopia City
is taken as a sample. While, the problem occurred in this automobile is most of time failure of
brake pads when braking is applied, and wear and fade of brake disc is occurred. Due to this kind
of problem some time accident is happen; so the cause of this kind of problem happens in brake
disc and brake pad of automobiles of TOYOTA HIACE minibus taxi that used in Ethiopian City
is the idealization of selection of good performance friction material of brake pad with
corresponding brake disc. Further, due to lack of consideration for selecting best friction material
of brake pad with environmental friendliness, in the case of TOYOTA HIACE automobiles dust
is produced from friction material of brake pad during braking time affect the aquatic life. Thus,
the study of mechanical properties of brake disc with interface of brake pad by finite element
method with the help of ANSYS software and experimental investigation of friction materials of
brake disc used in local City taxi is very important regarding to best braking performance of
automobiles and environmental protection.
Hence, as result obtain from analysis of finite element method with the help of software and
experimental result of laboratory test; for safe environmental protection, reducing (or) free of
Copper in brake pad of automobile especially in brake pad of TOYOTA-HIACE minibus 5L.
And the use of Al-MMC brake disc with Ceramic brake pad is best for braking performance of
automobiles rather than other interface.
