The economy brake kit has been a great seller for those that want good parts at a great price. This kit features rotors very similar to OEM rotors made by OP Parts, which is a quality brand that meets TUV Euro as well as Black Hat International standards of quality. Pads depend on what is in stock, but are generally a mix of either PBR Metal Master or Mintex Redbox for the front, and Pagid or Mintex for the rears. All offer excellent stopping capabilities. There are no problems mixing different pad brands
