If the rotor surface is deeply scored or warped, or
there is a complaint of brake roughness or brake
pedal pulsation, the rotor should be refaced using a
hub-mounted
on-car
brake
lathe
(Fig.
103),
or
replaced.
The use of a hub-mounted on-car brake lathe is
highly recommended to eliminate the possibility of
excessive runout. It trues the brake rotor to the vehi-
cle’s hub and bearing.
NOTE: All rotors have markings for minimum allow-
able thickness cast on an un-machined surface of
the rotor (Fig. 104) or stamped into the hat section.
Minimum
thickness
specifications
can
also
be
found in the specification table in this section.
(Refer to 5 - BRAKES/HYDRAULIC/MECHANICAL/
ROTOR - SPECIFICATIONS)
Minimum allowable thickness is the minimum
thickness which the brake rotor machined surface
may be cut to.
CAUTION: Do not machine the rotor if it will cause
the rotor to fall below minimum thickness.
Before lathe installation, verify the brake rotor
face and the hub adapters are free of any chips, rust,
or contamination.
When mounting and using the brake lathe, strict
attention to the brake lathe manufacturer’s operating
instructions is required.
Machine both sides of the brake rotor at the same
time. Cutting both sides at the same time minimizes
the possibility of a tapered or uneven cut.
When refacing a rotor, the required TIR (Total
Indicator Reading) and thickness variation limits
MUST BE MAINTAINED. Extreme care in the oper-
ation of rotor turning equipment is required. Specifi-
cations for brake rotor machining can be found in
this
sections
specification
table.

REMOVAL
REMOVAL - FRONT BRAKE ROTOR
NOTE: Before proceeding, (Refer to 5 - BRAKES -
WARNING)(Refer to 5 - BRAKES - CAUTION).
(1) Raise the vehicle. (Refer to LUBRICATION &
MAINTENANCE/HOISTING - STANDARD PROCE-
DURE)
(2) Remove the front tire and wheel assembly.
(3) Slide the caliper outward in an effort to retract
the caliper piston into its bore.
(4) Remove the two bolts securing disc brake cali-
per adapter to the steering knuckle (Fig. 105).
(5) Remove the disc brake caliper and adapter
from the knuckle as an assembly. Hang the assembly
out of the way using wire or a bungee cord. Use care
not to overextend the brake hose when doing this.
(6) Remove the clips retaining the brake rotor to
the wheel studs.
(7) Remove the brake rotor.
REMOVAL - REAR BRAKE ROTOR
NOTE: Before proceeding, (Refer to 5 - BRAKES -
WARNING)(Refer to 5 - BRAKES - CAUTION).
(1) Raise the vehicle. (Refer to LUBRICATION &
MAINTENANCE/HOISTING - STANDARD PROCE-
DURE)
