The brake pads were changed when I did my L5 engine conversion and the pads served me well in this 4 years of time. The wear of the pads were terrible and the right pad was already wore till the metal and started to make noise when I stepped on the brake pedal. Fortunately the brake disc is still in good shape even though being tortured by the wore out brake pads for almost a week.
I got them replaced by the new brake pads and the process of changing brake pads ain't troublesome. The tools that you needed were spanner, screw driver and a brake piston reset kit. Let's start the D.I.Y process after the jump.
