Chevrolet Captiva Service & Repair Manual: Brake Rotor Deglaze
| Caution: Whenever brake rotor
has been separated from wheel bearing flange, clean any rust or foreign
material from mating surface of rotor and flange with a suitable hub cleaning
kit. Failure to do this may result in increased lateral runout of rotor
and brake pulsation. |
| Caution: Improperly tightened
wheel bolts or nuts can lead to brake pulsation and rotor damage. In order
to avoid expensive brake repairs, evenly tighten wheel bolts or nuts to
proper torque specification. |
| 1. |
Remove tire and wheel assembly. |
| 3. |
Refinish brake rotors if one or more
of following conditions exist: |
| |
a. |
Brake rotor thickness variation in
excess of .001 inch. |
| |
b. |
Corrosion or pitting that is deeper
than rotor braking surface. |
| |
c. |
Scoring of rotor braking surface with
a groove depth in excess of .060 inch. |
| 4. |
Use a micrometer in order to measure
thinnest point of brake rotor. If thinnest point of brake rotor
exceeds brake rotor minimum thickness, do NOT refinish brake rotor.
Replace brake rotor. |
| 5. |
Deglaze rotor with a 120 grit aluminum
oxide sandpaper and a non-directional rotor finisher, if available,
to create a non-directional braking surface. |
| 6. |
Clean braking surfaces with denatured
alcohol or with a suitable brake cleaner. |
| 7. |
Thoroughly clean rust from brake rotor
flange. |
| 9. |
Install tire and wheel assembly. |
| 10. |
Burnish pads and rotors as follows: |
| |
a. |
Select a smooth road with little or
no traffic. |
| |
b. |
Accelerate vehicle to 30 mph. |
| |
c. |
Apply brakes to bring vehicle to a
stop, using moderate to firm pressure. Do not allow brakes to
lock. |
| |
d. |
Repeat steps two and three until approximately
20 stops have been completed. Allow sufficient cooling periods between
stops in order to properly deglaze brake pads and rotors. |
|
A small amount of denatured alcohol
may be used to ease assembly. Do not use soap.
