STANDARD PROCEDURES - DISC ROTOR
MACHINING
The disc brake rotor can be machined if scored or
worn. The lathe must machine both sides of the rotor
simultaneously with dual cutter heads. The rotor
mounting surface must be clean before placing on the
lathe. Equipment capable of machining only one side
at a time may produce a tapered rotor.
NOTE: A hub mounted on-vehicle lathe is recom-
mended. This type of lathe trues the rotor to the
vehicles hub/bearing.
Variation
CAUTION: Brake rotors that do not meet minimum
thickness specifications before or after machining
must be replaced.
