Sonata GLS V6-2.7L (2002)
Clean the disc thoroughly and remove all rust.
3. Place a dial gauge approximately 5 mm (0.2 inch) from the outer circumference of the brake disc, and measure the runout of the disc.
Limit: 0.03 mm (0.0012 inch)
NOTE: Tighten the nuts in order to secure the disc to the hub.
FRONT BRAKE DISC RUNOUT CORRECTION
1. If the runout of the brake disc is equivalent to or exceeds the limit specification, replace the disc and hub, and then measure the runout again.
1. Before removing the brake disc, chalk both sides of the wheel stud on the side at which the runout is greatest.
2. Remove the brake disc, and then place a dial gauge as shown in the illustration; then move the hub in the axial direction and measure the
runout.
If the play is equivalent to or exceeds the limit, disassemble the hub knuckle and check each part.
3. If the play does not exceed the limit specification, install the brake disc at a position 180° from the chalk mark, and then check the runout of
the brake disc again.
2. If the run-out cannot be corrected by changing the phase of the brake disc, replace the brake disc or turn the rotor with an on the car type brake
lathe ("MAD. DL-8700PF" or equivalent).
Be sure to follow the exact brake lathe manufacturer instructions. Rotors turned on the vehicle will often have a lower run-out than a new brake
disc.
FRONT BRAKE DISC THICKNESS CHECK
1. Using a micrometer, measure disc thickness at eight positions, approximately 45° apart and 10 mm (0.39 inch) from the outer edge of the disc.
