APPLICABILITY: ALL 1983 THROUGH 1985 SUBARU VEHICLE DATE 01-31-85

SUBJECT: BRAKE ROTOR RESURFACING
Please be advised that resurfacing of brake rotors is considered an acceptable procedure for warranty repair when performed by an authorized Subaru Dealer, using the following guidelines.

NOTE: This policy does not apply in an area where state or local law prohibits brake rotor resurfacing. State or local laws regulating rotor resurfacing must be adhered to when servicing a Subaru vehicle.

Resurfacing of a brake rotor to a thickness less than the usable limit, as noted in the applicable Subaru Service Manual, is not an acceptable repair.

For your information, the usable limits are as below:

ROTOR TYPE YEAR THICKNESS (MIN)

SOLID ROTORS (Front) 1983 (0.394 in.)
VENTILATED ROTORS (Front) 1983 and 1984 (0.610 in.)
VENTILATED ROTORS (Front) 1985 (0.630 in.)
SOLID ROTORS (Rear) 1985 (0.335 in.)

Because of the various types of brake resurfacing equipment available, we recommend that each Dealer become completely familiar with their respective unit and its operational characteristics and procedures.

Subaru brake rotors must be resurfaced within the run out/parallelism tolerances below, to ensure satisfactory results.

ROTOR TYPE RUN OUT (MAX) PARALLELISM (MAX)

ALL (0.004 in.) (0.0008 in.)

When performing brake rotor resurfacing under the terms of the Subaru Limited Warranty, refer to the brake system section (group 5) of the applicable Flat Rate Failure Code Manual for the appropriate operation numbers, times, and failure codes.
