Adjustment
Assemble the brake booster pushrod to the brake pedal assembly in order
to adjust the release switch assembly and the stoplamp switch assembly. An
incorrect adjustment may cause the cruise control system to work improperly.
Refer to
Stop Lamp Switch Replacement
in Brakes for more information about the stoplamp
switch adjustment.
Notice: Proper stoplamp switch adjustment is essential. Improper stoplamp switch
adjustment could cause brake drag and excessive brake lining wear.
Adjust the following components:
Important: Do not press the brake pedal assembly.
- Insert the cruise release switch assembly and stoplamp switch assembly
into the retainers until fully seated against the brake pedal bracket.
- Twist the switch in order to lock the switch into the desired
position.
- Measure the distance from the end of the threads on the switch
to the bracket. Ensure that the clearance is 1.55 to 1.7 mm (1/16 in).
Perform steps 1 and 2 again if necessary.
- Inspect for properly adjusted release switch assembly and for
stoplamp switch assembly using the following brake pedal assembly travel distance.
- The release switch assembly and the stoplamp switch assembly contacts
must be open at 3.5 to 12.5 mm (1/8 to 1/2 in)
brake pedal assembly travel. This is according to measurement at
the centerline of the brake pedal assembly pad. Nominal actuation
of the stoplamp switch assembly contacts is about 4.5 mm
(3/16 in) after the cruise control switch assembly contacts
close.
