A Nondirectional Surface Must Be Achieved
It is very important that, you make the rotor surface nondirectional by dressing the rotor surfaces with a sanding disc power tool such as AMMCO
8350 Safe Swirl Disc Rotor Grinder using 120 grit aluminum oxide sandpaper. Sand each rotor surface using moderate pressure for a minimum of
60 seconds. An alternate method is to use a sanding, block with 150 grit aluminum oxide sandpaper. With the rotor turning at approximately 150
rpm, sand each rotor surface using moderate pressure for a minimum of 60 seconds. After sanding the rotor, clean each surface with denatured
alcohol or a suitable brake cleaner.
CAUTION: The finished rotor surface should be as close to that of a new rotor as possible. Failure to obtain the best possible rotor finish can
affect initial braking performance.
