MAY CORRECTLY IDENTIFY THE SWITCH REQUIRING ADJUSTMENT. ALL COPIES OF 89-178-5 SHOULD BE DISCARDED.
Some vehicles may experience a condition of light brake drag while driving. These conditions have been found to be more noticeable on vehicles which
have an anti-lock brake system.
This may be caused by improper brake switch adjustment. If the brake switch is not adjusted properly, the switch may push on the brake pedal and cause
the brake to remain partially applied.
If a vehicle exhibits any of the above conditions, perform the following functional brake switch adjustment check:
Passenger Cars Only:
The following steps should be used to check brake switch adjustment:
1.
Remove the driver-side hush panel (refer to Figure 1).
2.
Gently pull back on the brake pedal until no audible clicks are heard. The switch will be moved in the tubular retainer providing adjustment.
3.
Replace the hush panel.
4.
Verify that the brake drag condition is no longer present and that the cruise control and brake lights function properly.
