Vehicle Reassembly - Pro-Cut PFM 9.2 DRO Technical Manual

MACHINING ROTORS

VEHICLE REASSEMBLY

Be sure to torque all lug nuts to manufacturer's specification with a torque wrench or other calibrated tool. Excess
or uneven torque can deflect the rotor and actually induce additional run-out, destroying the accuracy of the rotor
matching process.
When machining (and any optional sanding) is complete on both sides, all debris must be removed and rotor sur-
faces completely cleaned with soap and water. Cast iron dust left on the rotor can cause brake noise. All surfaces
should be cleaned of chips and dust. Special care should be used in making sure that ABS sensors are free of
debris. Reassemble the brakes and wheels to the manufacturer's specifications.
HELPFUL HINTS FOR CUTTING ROTORS USING A PRO-CUT LATHE
– Inspect cutting tip edge for wear and damage.
– Be Sure that the gib is properly adjusted on the slide plate.
– Be sure that the vehicle is in neutral
– Remove the wheel and caliper on both sides of the vehicle and stabilize the opposing rotor so it does not rock.
– Be sure that the Emergency Brake is released.
– If ambient temperature is well below freezing and the vehicle is all-wheel drive, warm vehicle up by driving
for 5 minutes.
– If cutting a vehicle with limited slip, disconnect the drive shaft if resistance is too great.
– If there is an electronic traction control control switch, turn it to 'off'.
