Abstract
Penelitian ini membahas analisis perbandingan kualitas produk kampas rem jenis cakram (disc brake) antara original dengan aftermarket . Analisis dilakukan pada hasil uji tribologi (uji friksi dan keausan), uji kekerasan, komposisi kimia dan struktur mikro untuk mengetahui ketahanan gesekan dan aus serta bahan yang digunakan. Dari hasil uji diperoleh perbandingan kualitas kampas rem original dan aftermarket yang lebih baik adalah original dimana nilai koefisien
friksi 0,14 dibanding 0,11, sedangkan keausan (kondisi normal) 1.35 x 10-7 g/mm2.detik dan 1.22 x 10-6 g/mm2.detik. Dari uji kekerasan diperoleh kampas rem original kekerasan rata-rata 65.567 HVN dan untuk aftermarket adalah 13.983 HVN, untuk hasil uji komposisi kimia dan struktur mikro menunjukan bahwa material kampas rem original menggunakan serat penguat berbahan karbon (C), tembaga (Cu), Besi (Fe) dan Alumunium (Al). Sedangkan bahan serat penguat yang
terdapat pada kampas rem aftermarket adalah asbes, karbon (C), alumunium (Al) dan besi (Fe).
