Chevrolet Cobalt Service & Repair Manual: Parking Brake Cable Adjust
Refer to Fig. 1
when performing the following procedure. |
1. |
Apply and fully release the park brake
several times, then verify that the park brake lever releases completely. |
2. |
Turn ON the ignition. Verify the red
brake warning lamp is not illuminated. |
3. |
If the red brake warning lamp is illuminated,
verify the following: The park brake lever is in the fully released
position and against the stop, and there is no slack in the park
brake cables. |
4. |
Turn OFF the ignition. |
5. |
Release the park brake lever boot from
the floor console by applying light pressure inward on the sides
of the boot retainer and pull the boot back. |
6. |
With the park brake lever in the released
position, loosen the adjusting nut (1) enough to completely relieve
tension on the front cable. |
7. |
Raise and support the vehicle, then
raise the vehicle just enough to observe the rear calipers and rotate
the rear tire and wheel assemblies. |
8. |
With all tension relieved from the
park brake cables, rotate the rear tire and wheel assemblies, or
the rear brake rotors if the wheels have been removed. Observe the
amount of effort required for rotation and the amount of drag if
present. |
9. |
Tighten the park brake cable adjusting
nut (1) until all slack is taken out of the front cable. |
10. |
Further tighten the adjusting nut (1)
until one of the park brake levers on the rear calipers is just
lifted off the stop on the caliper housing. |
11. |
Slowly back off the adjusting nut until
the park brake lever just rests on the stop. |
12. |
Back off the adjusting nut one full
turn. |
13. |
Fully apply and release the park brake
lever 3-5 times. |
14. |
Raise the park brake lever three detent
positions and attempt to rotate the rear tire and wheel assemblies,
or the rear brake rotors. If rotating the tire and wheel assemblies,
they should be difficult to rotate, but should not be locked. If
rotating the brake rotors, they should be locked. |
15. |
Raise the park brake lever one additional
detent position and attempt to rotate the rear tire and wheel assemblies,
or the rear brake rotors. The tire and wheel assemblies, or the
rear brake rotors should be locked. |
16. |
Fully release the park brake lever. |
17. |
Verify the park brake is released by
rotating the rear tire and wheel assemblies, or the rear brake rotors.
The rotors should rotate freely and exhibit no brake shoe drag from
the park brake system. |
18. |
With the lever released, if the rotors
required more effort to rotate, or exhibited more drag than noted
previously when all cable tension was relieved, check the park brake
levers on the rear calipers. The levers should be on the stops. |
19. |
If the levers are not against the stops,
loosen the adjusting nut just until the levers rest against the
stops, then repeat steps 13-17. |
20. |
If the rotors still do not rotate freely,
with the park lever fully released, park brake adjustment is not
the cause of any drag in the brake system. |
21. |
Lower the vehicle, and position the
park brake lever boot to the floor console and press the boot retainer
into place to secure. |
22. |
Release the park brake lever. |
