Skylark V6-173 2.8L VIN X 2-bbl (1984)
After the rotor has been sanded, the surfaces must be cleaned with a solvent such as GM Brakes Parts Cleaner #12345754, denatured alcohol, or
equivalent.
THE FINISHED ROTOR SURFACE SHOULD BE AS CLOSE TO THAT OF A NEW ROTOR AS POSSIBLE. FAILURE TO OBTAIN THE BEST
POSSIBLE ROTOR FINISH WILL AFFECT INITIAL BRAKING PERFORMANCE.
CAUTION: ROTORS OR DRUMS SHOULD ALWAYS BE REPLACED IF TURNING WILL RESULT IN A ROTOR OR DRUM THAT DOES
NOT MEET MANUFACTURER SPECIFICATIONS FOR MINIMUM ROTOR THICKNESS OR MAXIMUM DRUM DIAMETER.
NOTICE:
When re-installing the tire and wheel assemblies, it is very important that proper procedures be followed when installing and torquing
the wheel nuts:
A.
Finger start all wheel nuts.
B.
Tighten wheel nuts to specified torque (use the "star", or alternating nut pattern) using a torque wrench.
DO NOT USE AN IMPACT WRENCH. UNEVEN AND/OR EXCESSIVE TORQUING OF THE WHEEL NUTS HAS BEEN FOUND TO
DISTORT ROTORS, RESULTING IN PREMATURE CUSTOMER COMEBACKS FOR BRAKE PULSATION.
3.
After the brake pads have been replaced and/or the rotors have been refinished, it is recommended that the new braking surfaces be
broken in, or burnished, to properly seat them. This can be accomplished by making 20 stops from 30 mph, using medium to firm
pressure. Care should be taken to avoid overheating the brakes.
4.
It is strongly recommended that the correct, specified General Motors replacement part(s) be used when servicing G.M. vehicles.
General Motors does not test non-G.M. parts for proper performance on G.M. vehicles. Therefore, the use of non-G.M. parts may result
in unacceptable vehicle performance. It is also important that the correct G.M. part(s) be used in the correct G.M. application.
