Brake discs do not require a detailed procedure as brake pads require.  By following the brake pad bed-in procedure will result in your discs being completely bedded.  If you purchase pre-bedded pads from G-Loc™ then all you need to do is install the pads and hit the brakes 3-5 times (while driving).  This will get the two surfaces (disc and pad) to mate up and put down a transfer layer into the micro-grooves on the discs.  You should always clean a new disc’s surface before installing.  By cleaning the disc surface, you will have completely removed any and all surface residue and debris that might contaminate or damage the brake pads.
