4B-22 Front Brakes:
Callout
Disc Brake Rotor
Tip:
1. If installing a new brake rotor, clean the friction surfaces of the brake rotor with denatured alcohol.
2. If reinstalling the original brake rotor, mark the relationship of the rotor to the wheel hub.
3. Using the J 42450-A, thoroughly clean any rust or corrosion from the mating surface of the hub/
axle flange.
4. Using the J 41013, thoroughly clean any rust or corrosion from the mating surface of the rotor to
the hub/axle flange.

5. If the brake rotor is to be machined, check the thickness variation measurement. Refer to "Brake
Rotor Thickness Variation Measurement: ".
6. After installing the brake rotor, measure the assembled lateral runout (LRO) of the brake rotor.
Refer to "Brake Rotor Assembled Lateral Runout Correction: ".
7. If the brake rotor assembled LRO measurement exceeds specification, bring the LRO to within
specification. Refer to "Brake Rotor Assembled Lateral Runout Correction: " - Indexing.
8. If the brake rotor was refinished or replaced, burnish the pads and rotors. Refer to "Brake Pad and
Rotor Burnishing: ".
Brake Rotor Surface and Wear Inspection
WARNING
!
Refer to "Brake Dust Caution: ".
1. If the inboard friction surface of the brake rotor is not
accessible, reposition and support the caliper with
the brake pads. Refer to "Front Disc Brake Pads
Replacement" and/or "Rear Disc Brake Pads
Replacement: ".
2. Clean the friction surfaces of the brake rotor with
denatured alcohol, or an equivalent approved brake
cleaner.
3. Inspect the friction surfaces of the brake rotor for the
following Braking Surface Conditions:
– Heavy rust and/or pitting
Light surface rust can be removed with an
abrasive disc. Heavy surface rust and/or pitting
must be removed by refinishing the rotor.
– Cracks and/or heat spots
– Excessive blueing discoloration
4. If the friction surfaces of the brake rotor exhibit one
or more of the Braking Surface Conditions, the rotor
requires refinishing or replacement.
Component Name
5. Using a micrometer calibrated in thousandths-of-a-
millimeter, or ten-thousandths-of-an-inch, measure
and record the scoring depth of any grooves present
on the rotor friction surfaces.
6. Compare the groove scoring depth recorded to the
following specification:
Specification
Brake rotor maximum allowable scoring: 1.50
mm (0.059 in)
7. If the brake rotor scoring depth exceeds the
specification, or if an excessive amount of scoring is
present, the rotor requires refinishing or
replacement.
