Eicher Brake Pads....

[TonyHSD]

ABS Discs Yes, I use them in the past with EBC pads, brilliant combination. Only negative for the discs was that they didn’t have anti corrosion paint but in U.K. with that much of a rain even with that paint they still get rusted. Ridex never used. If you changing the discs only you better don’t change them at all, this is wrong wrong wrong. You can change pads only , also not recommended but only discs with old pads ......

The online prices are not a factor or warranty against fake parts, shopping on eBay Amazon can save you a fortune but you need to know from who and how, packing also not guarantee, there are old stocks sometimes with older packages for sale, inside same parts. If you not sure just buy from where you like it, I can only recommend you to get a new pads too and install them properly, cleaning, lubricating, brake fluid change etc. Proper brake job it’s not only about taking an old parts off and putting a new ones. After you change them take it easy on the brakes in the first 500 miles. 
Good luck
