Honestly, I don't know. The better pads are Isuzu pads from Merlin. From what I understand it is not what they are made of, but the thickness of the pad. But then again, I don't really know. It could be the material as well...
I always forget about Merlin. I have bnought from him before and had a great price and service but everytime I need something elseI forget til someone reminds me. Thanks
