Replaced Green Stuff pads on our Dodge Ram 2500, pleased with Yellow Stuff performance with added bite. The performance was immediately noticeable, they still need to be broken in. The new EBC pads come with piston pad seals, previously a seal fitted to the back of the pads was used. Two of the four legs were missing. I called EBC and they sent me two more piston pad seals. Great customer service from EBC Brake!
