I remember a story on the news a while back, brake pads coming in from china were being madeof compressed grass, sawdust and cat litter! For some reason, they were catching fire soon after being fitted... But at least were cheap I: Not sure about anyone else, but i think the cost od discs and pads are realitively inexpensive anyway. I did my brothers fiesta the other week. I bought mintex discs and pads from the local spares centre. Discs were £16 a pair. Pads were £12 set of 4. Not sure its worth looking to find a cheap version! Just stick with a brand you have heard of and you cant go far wrong.
With some people the difference between whats cost effrective and whats worth it is vastly different.
Unknown brand budget brakes are a gamble and saving a few quid could be risky. To me OE spec by known names is cost effective as you know you have quality, they are up to the job but not expensive. Super drilled and grooved mega temperature discs with a ultra racing compound pads that still work when the disc glows with heat to me is a waste of money. Others will say they are better than standard so its worth it. They may cost 4 times as much but they will say you cant put a price on safety. You choice at the end of the day!
